39 Operator s Manual RadSeeker CS/CL Overview Operation from External Supply The instrument can be operated from an external AC or DC source using the appropriate supplied power adapters. Protection from reverse polarity, over voltage, and electrical noise are provided. External power sources include: A 12 VDC power supply (supplied) operated from a vehicle electrical system A regulated 12 VDC power supply operating from utility power (supplied) Over-range Indicators Neutron saturation: indicated when neutron count rate exceeds the neutron detector s saturation level of 30,000 counts per second. The neutron count will display as 1.8 million counts per second (30,000 cps) when the count is at or above this rate. Gamma saturation: indicated when gamma count rate exceeds the detector s saturation level of 500,000 counts per second. The system will power down the detectors, both gamma and neutron, to prevent damage to the instrument when the gamma saturation level of 500,000 cps is reached. The operator should move to an area of decreased radiation, and can then re enable the detectors Dose Rate Range The minimum gamma dose rate reading is 1 μrem/hr or 0.01 μsv/hr, depending on the setting of dose rate units (Rem or Sievert). The maximum dose rate displayed is limited by the gamma saturation count rate level (refer to Over range Indicators on page 2 17). Beyond this count rate, the detectors will shut off. The following tables illustrate the approximate sample dose rates that will occur for the indicated source at the saturation rate of 500,000 cps RadSeeker CL Table 2 6 Dose Rate Range (LaBr 3 ) Source Maximum Dose (μsv/hr) Maximum Dose (mrem/hr) Am Cs Co Revision B, August Technical Specifications

ANSI N42.34 provides instructions for converting exposure rate (R/h) to dose equivalent rate (Sv/hr or rem/hr). Applicable conversion factors are found in ISO The following conversions will be used to correct exposure rates from 137 Cs sources to dose equivalent rate. Deep Dose Equivalent (rem/hr) = Exposure Rate (R/hr) * C k * C x Where: C k = 1.21 rem/rad for 137 Cs, H p (10) (ISO 4037 Table 33) C x = rad/r This yields: 1 rem/hr = 1.06 R/h FWHM Specifications NaI detector better than 7.5% at 662KeV (RadSeeker CS) LaBr 3 detector better than 3.5% at 662KeV (RadSeeker CL) Technical Specifications 2 18 Revision B, August 2011

41 Operator s Manual RadSeeker CS/CL Overview Detector Peak Efficiency Efficiency (%) Peak RadSeeker CS RadSeeker CL 122 KeV KeV KeV KeV KeV Confidence Of Identification The QFN (Quality Factor Number) recorded in the ICD2 files for each isotope is the variable used to measure the confidence associated with isotope identification. For an isotope to be considered identified it must have a QFN value greater than 0.04, however, depending on the QFN associated with the isotope the confidence of identification is classified as either: low, medium or high. The QFN thresholds used for the confidence classification are based on quantitatively determined values that ensure that there are the maximum number of correct answers and minimizing the number of false negatives. These values have been generated based on ROC curves generated from the extensive set of identifications for many source scenarios. The current chosen values are provided in Table 2 8. Table 2 8 Isotope identification confidence classifications and the related QFN thresholds Value Confidence Low Medium > 0.4 High Based on our regression data set the statistical confidence in the Identification using the chosen QFN ranges have been calculated for the RadSeeker detectors and are shown in Table 2 9. Table 2 9 Relationship between confidence categories and the percentage of true identifications Confidence QFN Range Percentage True Low Medium High Revision B, August Technical Specifications

42 Figure 2 10 shows how the number of false identifications and the percentage of true identifications vary with QFN value in the regression data set. The figure can be used to obtain a measure of confidence of an identification of an isotope with a given QFN value. Figure 2-10 A plot of QFN value against the percentage of false identifications and the number of correct identifications NOTE: RadSeeker CS/CL does not have a standby mode. Time to start an identification sequence from the a screen saver mode is instantaneous (1 2 seconds) Data File Formats Three files are created with each identification. The three files are referred to as Interface Control Document (ICD); ICD1, ICD2 and N The ICD1 and ICD2 file formats adhere to a DNDO standard and end with _U.n42 and _AA_01.n42 respectively. The N42.42 files adhere to the 2011 Draft ANSI N42.42 standard and end with N42.n42. Technical Specifications 2 20 Revision B, August 2011

49 Operator s Manual Basic Operation Chapter 3 Basic Operation WARNING! The primary purpose of the RadSeeker CS/CL is to detect and identify radioactive material. This is a detection instrument that is designed to recognize and identify small signals from the energy profiles of isotopes. This is not a safety device or a personal safety monitor. 3.1 Pre-Check The detector needs to be above 4 F ( 20 C) for the unit to start up. The normal operating temperature is 25 F ( 32 C) to 122 F (50 C). For extreme conditions allow extra time for the detector to acclimatize. Before setting off for the inspection site, you should collect the accessories you need. The detector should always be transported in its carrying case. Refer to Transporting the RadSeeker CS/CL on page Dirt can make the detector s screen difficult to read, or make it slippery to handle. It is best to begin any assignment with clean equipment. Refer to Cleaning the RadSeeker CS/CL on page For most applications, you will use the batteries to power the detector. You need to take enough charged batteries to complete the job. Revision B, August Pre-Check

50 3.2 Startup To start the RadSeeker CS/CL: 1. Press and hold the Power key for 3 5 seconds. Look for the green and red LED s. Release the Power key as soon as they light up. 1 Figure Select key RadSeeker CS/CL Unit The startup splash screen opens. Figure 3-2 Startup Splash Screen Startup 3-2 Revision B, August 2011

51 Operator s Manual Basic Operation 2. After the operating system has loaded, the application starts and the unit automatically runs through a self test cycle. NOTE: The self test includes operating the LEDs, the beeper, and the vibrator. Figure 3-3 Self-Test in Progress 3. The RadSeeker CS/CL starts its self calibration process during the self tests. NOTE: The unit can take up to two minutes to become fully operational, from a powered off state. 4. After the self tests complete successfully, a (Pass/Fail) message is displayed on the screen, and written to the system log. If a component fails, the warning message will scroll across the bottom of the screen. Figure 3-4 Self-Test Passed but Still Calibrating NOTE: If the unit reports a Low Battery condition, replace the battery. Attach the detector to external power before swapping the batteries. Revision B, August Startup

52 After completion of the Self Test the unit begins stabilizing. The status area displays Stabilizing until the completion of the self calibration process (approximately 30 seconds). Figure 3-5 Detector Stabilizing 5. Upon completion of the self test and system stabilization, the display switches to the Detect and continues to collect a new background. After completion the invalid background message is turned Off. Figure 3-6 Detect Mode Startup 3-4 Revision B, August 2011

53 Operator s Manual Basic Operation 6. If any of the self tests fail, the system generates an alarm and displays an appropriate message. Figure 3-7 Self-Test Failure 7. Acknowledge the alarm by pressing the Select key. Follow any instructions provided in the error message. Figure 3-8 Self-Test Failure - System Message NOTE: The results (Pass/Fail) are displayed on the screen and written to the system log. Failure messages scroll across the bottom until the system has determined the problem no longer exists. NOTE: If the unit reports a Low Battery error, replace the battery. Refer to Removal and Replacement of the Battery on page If errors prevent the use of the unit, report it to the service department. Revision B, August Startup

54 3.2.1 Stabilizing The RadSeekerʹs gamma detector is calibrated at the factory prior to shipping. The calibration parameters are stored in the unit, and with normal use, the RadSeeker will not require any periodic recalibration over the lifetime of its components. Changes in operating environment (such as temperature, electromagnetic fields, etc) can cause a gamma detector to drift around its calibration point, reducing performance. In order to compensate for these effects, the RadSeeker incorporates a patented method of stabilization that continually keeps the unitʹs calibration accurate. The stabilization system uses a small (<200Bq) internal sealed Na 22 source. 1. On startup, the RadSeeker finds the 511keV peak from this source, adjusts the system so that the peak is located correctly at 511keV on the energy scale, then locks onto it, checking every 30 seconds or so and making fine adjustments to keep it in place. 2. Should the peak make a drastic shift, the RadSeeker recognizes this fact and goes into ʺStabilizingʺ mode, preventing the operator from performing an identification during a time when the systemʹs performance may be affected. 3. Once stabilization is reacquired, the unit returns to ʺDetectʺ mode. The advantage of this approach is that the system is thoroughly checked using an actual gamma source, and yet because gammas from this source are collected in a separate spectrum, there is very little of this source seen in the main spectrum that is collected for identification. NOTE: NOTE: If the RadSeeker is exposed to a very strong magnetic field, it may lose stabilization for a period of 30 to 60 seconds but will re stabilize. Once the unit is no longer subject to the field it will go through the same stabilization cycle. The service life of the handheld unit is 8 years. If the service life of the handheld unit is extended, the stabilization module will have to be replaced which replaces the Na 22 source. 3.3 Manual Shutdown To shutdown the RadSeeker CS/CL: CAUTION! Never remove the battery, or pull the plug to shutdown the unit. This may cause loss of data or corruption of the software. 1. Press and hold the Select key for 5 seconds. The display shows the shutdown message. NOTE: In the event the application is not running correctly (for example, the display or key pad is unresponsive), press and hold the Select key for 15 seconds to force the RadSeeker CS/CL to shutdown. Manual Shutdown 3-6 Revision B, August 2011

55 Operator s Manual Basic Operation Figure 3-9 Select Key Auto Shutdown This occurs when connected to the power supply, and the unit is idle for 5 min. This feature is disabled by default and can be enabled/disabled in Advanced Mode, refer to Advanced System Configuration on page 6 9. a. The software recognizes that the unit is plugged in, and may have been left On unintentionally. It gives a 30 second count down and then shuts down. or b. If the unit is connected to the USB, instead of a full shutdown, it only shuts Off the gamma and neutron detectors. Press Select (the middle key) to reactivate the detectors. NOTE: If the USB is disconnected the RadSeeker may continue to run as though it is still connected. Cycle the Power (turn Off then On) to restore normal functionality. 3.4 Detection The system displays the real time count rate from the detector subsystem for both neutron and gamma radiation with no input necessary from the user. In Detect mode, the unit shows the count data and dose rate values on the right hand side of the display and the time plot on the left hand side. The display provides a historical graph of the intensity of the source. To localize the radiation source(s), use the graph to determine if the source is getting closer or further away. Revision B, August Detection

56 Additionally, the unit has an Audible Dose rate Indicator (ADI) which provides an auditory equivalent to the visual historical graph. To activate: 1. Press ADI On from the Detect screen. The ADI is now active. The unit will begin to beep at 10 μrem/hr above the ADI activation dose rate. For example, if the ADI is activated when the dose rate is 2 μrem/hr, the unit will beep at 12 μrem/hr. As the unit gets closer to a source, the beeping will increase in frequency. Conversely, as the unit moves away from a source, the beeping frequency will decrease. NOTE: The ADI sound is only audible in the Detect mode. If the user goes to ID Mode, or any other mode from Detect, the sound stops. Also, any Alert or Alarm disables the ADI sound. 1 2 Figure 3-10 Audible Dose Rate Indicator button 1. ADI ON 2. ADI OFF 2. To turn off the ADI, press the ADI Off button. Detection 3-8 Revision B, August 2011

57 Operator s Manual Basic Operation Identification To perform an identification: 1. Press the Start ID key on the Detect screen to start the identification process. Figure 3-11 Detect Mode Screen 2. Inspect the target by moving the detector slowly across the surfaces of interest in a methodical way. It is best to cover the full width and height of a container, where this is possible. 3. Keep the detector close to the item of interest for best results. Try to stay close, but avoid bumping or banging into the target. The detector is multi directional for gamma radiation. You do not need to point the front of the detector. The neutron detector may provide more sensitivity when vertical or sideways on, because of the long and narrow tube that runs the length of the handle. 4. The detector subsystem collects spectrum data for the default period of 30 seconds. 5. The system collects spectrum data and completes the identification process unless the user cancels the process or forces an early identification. A progress bar provides a visual indication of the data collection time The value to the left of the progress bar is the time of data collection remaining Revision B, August Detection

91 Operator s Manual Normal Mode Chapter 4 Normal Mode 4.1 System Power States The system has two power states: battery power and external power. In each of these power states there are two power modes: For Battery Power: Standby Enabled and Standby Disabled (refer to Standby Power Mode on page 3 21). For External Power: Auto Off Enabled and Auto Off Disabled (refer to External Power on page 4 1). To configure the Standby Power Mode and the Auto Off Power Mode, refer to Advanced System Configuration on page 6 9 for further instructions External Power In the External Power state, the RadSeeker CS/CL either has Auto Off Enabled or Disabled. If enabled: The unit will turn itself Off following a period of inactivity. The user is alerted 30 seconds prior to shutdown and shown the progress of the timer to shutoff. Refer to Figure 4 1. NOTE: The Auto Off interval is a configurable setting. The factory default is five minutes. Figure 4-1 Unit Time to Power Off Revision B, August System Power States

92 If the RadSeeker CS/CL is connected and communicating to a PC via a USB cable, only the detectors, rather than the entire unit, will power Off. Refer to Figure 4 2 and Figure 4 3. Figure 4-2 Detector Power Off The following screen displays with a message to Press Select key to Re Enable Detectors.

93 Operator s Manual Normal Mode Normal Mode The normal mode main menu is reached from the detect screen by pressing the key with the Menu label above it. The following sections describe the menu options available in Normal mode. Figure 4-4 Menu List NOTE: Any changes made to the Normal mode configuration are reset back to the factory default settings upon power cycling the unit (powering it Off and back On) Collect New Background To properly interpret the radiation from targets, the detector needs an accurate picture of what is normal. The natural resources and the environment affect background levels, as we move from location to location. Examples of NORM sources: Radon gas, presence of radium and thorium, plant life and other natural radiation emitting sources create an energy signature that is normal for a particular place. As the detector is used in different locations, it is important that the measured background is tailored to the inspection location. The detector assesses the background every 30 seconds, and when the background spectrum needs to be replaced because it is different than the current background, a default setting of 300 seconds (5 minutes) is used for the new spectrum. The value of the background is that it provides a graph of the levels of gamma radiation that can be used as a baseline for measuring differences. This clarifies the radiation contribution of a target that should be compared to the characteristics of known sources. NOTE: When a new background collection is implemented, either from a Manual or Active background process, the Gamma and Neutron background will both be updated. Revision B, August Levels of Functionality

94 To collect a new background: 1. Select Menu from the Detect screen. CAUTION! Do not move while the background collection is in process. 2. Select Collect New Background from the Normal Mode Functions screen. The unit displays the screen shown in Figure 4 5. Pressing the Cancel button stops the new background collection. NOTE: Cancelling the new background collection causes the unit to return to using the background that was in use prior to the start of this collection. Figure 4-5 New Background Collection 3. The system informs the operator when background collection is complete, refer to Figure 4 6. Figure 4-6 Manual Background Complete Levels of Functionality 4 4 Revision B, August 2011

95 Operator s Manual Normal Mode 4. Press the Select key to acknowledge and return to Detect mode. NOTE: If Active Background collection is enabled (refer to Active Background on page 4 5), when a manual background collection is initiated, the Active Background is temporarily suspended during the manual collection time. After the manual background collection is complete and the user chooses Yes/No, the Active Background mode then resumes. This may take up to 5 minutes depending on background. While Active Background is Enabled, then any time the current background appears to be significantly different from the manually collected background, the system will inform the user that it is implementing a new background and that the manually collected background is no longer in use (refer to Figure 4 7). Refer to Active Background on page Active Background The system can be configured to actively collect background without operator initiation. Table 4 1 Active Background During an Analysis The system determines a new background is needed The operator is running through a manual self-test The operator is in the process of conducting an identification Operation The operator is notified for a short period of time (10 seconds). This display situation will appear at any time, similar to an alert or alarm condition. The active background process will wait until the operator has completed the self-test before displaying the new background status. The background process is temporarily halted. 1. Figure 4 7 indicates New Background has been implemented. Figure 4-7 New Background Implemented Message Revision B, August Levels of Functionality

The details of this alarm are written to the system log for later review Active Background Updates When the system is powered On with Active Background ʹenabledʹ, or whenever Active Background is switched from ʹdisabledʹ to ʹenabledʹ, it evaluates the background environment to determine if this background is same as the one it was last using. The message Evaluating Background... always occurs on power up when Active Background is enabled, or anytime the system moves from an area of higher to lower background and needs to reevaluate. During this evaluation time, which can take anywhere from 30 seconds to a few minutes, a notification is shown in the message bar: ʺEvaluating Background Background subtraction not being usedʺ. Refer to Figure 4 9. Levels of Functionality 4 6 Revision B, August 2011

97 Operator s Manual Normal Mode Figure 4-9 Evaluating Background Indication NOTE: The notification will disappear after analysis indicates that the current background is equivalent to the stored background. After a certain time (defined by Active Interval; refer to Background Settings on page 6 7), if the backgrounds do not prove to be similar, the stored background is replaced with the background collected during this time period. The ʺEvaluating Backgroundʺ notification disappears at that time. Background subtraction is disabled whenever the message ʺEvaluating Background Background subtraction not being usedʺ is displayed. While it is possible to perform identifications during this time, for most accurate identification results it is recommended that the operator wait until background evaluation is complete prior to performing identifications. Identifications performed without background subtraction may in some cases include indications of non present radionuclides. ICD files saved during this condition may not have a background spectrum included, and will have a <Background State Invalid=ʺtrueʺ> tag present in the ICD1 file to indicate this condition Adjust Brightness Refer to Adjust Brightness on page 3 16 for further instructions Adjust Volume Refer to Adjust Volume on page 3 17 for further instructions.

143 Operator s Manual Alerts and Alarms Chapter 5 Alerts and Alarms 5.1 Types of Alerts and Alarms The RadSeeker CS/CL notifies the operator when Alerts or Alarms happen. An alert is information that may be useful to an operator; an alarm is generally something of more importance that an operator is required to act on. There are three categories of Alerts and Alarms: Threshold Alerts/Alarms inform the operator when some measure of radiation has reached a threshold. These can occur at any time during operation. Identification Alarms inform the operator that radionuclides have been identified as a result of an identification operation. System Alarms can happen at any time and provide the operator with critical information about the functioning of the system, such as low battery conditions or system failures Hysteresis for Threshold Alerts / Alarms When radiation levels hover near a threshold value, repeated alarms could become a nuisance for an operator. For instance, after acknowledging an alarm, if the radiation level dipped below the threshold and then rose again, the operator could be presented with another alarm immediately. To prevent alarms from recurring in rapid succession, a recovery period or ʺhysteresisʺ is applied to some threshold type alarms. Once the threshold is exceeded, the alarm persists for a configurable time period after the underlying condition goes away. The default hysteresis period is 10 seconds; this means that once an alarm occurs, it cannot re occur for 10 seconds after the underlying radiation condition subsides. If the levels go below, then back above the threshold within this time period, it is considered to be a continuation of the previous alarm, rather than a new alarm. The specific alerts/alarms that use this hysteresis mechanism are: Gamma Detection Alert High Gamma Dose Rate Alarm Neutron Detection Alarm Revision B, August Types of Alerts and Alarms

144 5.1.2 Alarm Indicators The system has 4 different alarm indicators. The alarm indicators are: Display (refer to OLED Display on page 2 3) Audible Indicator (beeper and headset, refer to External Power Connection on page 2 9) LEDs (refer to LED Indicators on page 2 11) Tactile Indicator (refer to Tactile Indicator on page 2 11) 5.2 Gamma Detection Alert The gamma detection alert is disabled by default in the RadSeeker CS/CL. This section describes how this feature works when enabled. It may be enabled using Advanced mode. The unit displays an alert when gamma radiation rises over the background by an amount determined by the configurable threshold value. This alert can happen at any time during operation. Figure 5-1 Gamma Detection Alert 1. The unit displays the alert until the user acknowledges it, at which point the unit returns to displaying the Detect screen or whichever screen the unit was operating prior to the alert. Gamma Detection Alert 5 2 Revision B, August 2011

145 Operator s Manual Alerts and Alarms 2. The gamma count rate is highlighted in red for as long as the threshold is exceeded. The times during which the threshold is exceed is also shown in the histogram, indicated by yellow colored bars where the gamma count is above threshold. Figure 5-2 Gamma Detection Alert in Detect Mode The alert messages remain on the screen as long as the gamma gross count remains above the threshold value. The threshold has a hysteresis feature to prevent the system from repeatedly alerting when the count rate near the threshold value. Once the alert occurs, the count rate must return below threshold level and remain there consistently for the ʺhysteresisʺ time in order for the system to alert again. The hysteresis time is configurable in Advanced Mode and defaults to 10 seconds. Revision B, August Gamma Detection Alert

146 5.3 High Gamma Dose Rate Alarm The High Gamma Dose Rate alarm Refer to Figure 5 3 is a personal hazard alarm which triggers when the gamma dose rate exceeds the Advanced Mode configurable threshold value. By default, this threshold is set to a dose rate of 20 mrem/hr. It is adjustable from 1 to 20 mrem/hr from the Advanced Menu. Refer to Adjust Alarm Thresholds on page 6 4. The dose rate is calibrated for Cs 137; dose rates from gamma signals of different energies may be reported with less accuracy. For examples, refer to Dose Rate Range on page Press the Select key to acknowledge the alarm. Figure 5-3 High Gamma Dose Rate Alarm At this point the unit displays the alarm status message at the bottom of the Detect screen. This message remains on the screen as long as the high gamma dose rate condition exists. Figure 5-4 High Gamma Dose Rate in Detect Mode High Gamma Dose Rate Alarm 5 4 Revision B, August 2011

147 Operator s Manual Alerts and Alarms 2. Follow your local Standard Operating Procedure in response to an alarm indicating that the programmed dose rate threshold has been exceeded. 5.4 Gamma Saturation Alarm At any time during operation, if the gamma count rate exceeds the fixed threshold of 500,000 counts per second, the system will issue a Gamma Saturation Alarm. Refer to Figure 5 5. Figure 5-5 Gamma Detector Shutoff At high count rates, the gamma detector could be damaged. In response to this alarm, the system powered down the detectors to prevent possible damage. 1. Press Select to acknowledge the Gamma Saturation Alarm. 2. The system indicates that the detectors have been powered down, and advises the operator to re enable the detectors once the unit has been moved to an area of lesser radiation that is safe for the detector to operate in. Figure 5-6 Gamma Detector Shutoff Revision B, August Gamma Saturation Alarm

148 CAUTION! Move a safe distance from the source. Follow the appropriate SOPs for this type of situation. 3. Press Select to restart the detectors. NOTE: During the time the detectors are powered off, there is no radiation data presented, and no further radiation based alarms are possible. 5.5 Neutron Detection Alarm The Neutron Detection Alarm is triggered by a neutron count exceeding an adjustable threshold over background, as shown in Figure 5 7. The user can configure this threshold value in Advanced mode. Refer to Adjust Alarm Thresholds on page 6 4. When, the neutron count rate exceeds the threshold over background, the N cpm number turns red, and the histogram bars are colored red. Periods below the threshold are shown in the histogram as white. You should follow your SOPs in the handling of neutron alarms. Performing an identification can provide more information on neutron presence. If found, neutrons are listed in the isotopes list. Figure 5-7 Neutron Alarm Display This event also causes the unit to create ICD1/ICD2 files, which captures the event, however the data in these files may not be useful for analysis, as only an instantaneous snapshot of count and dose rates are presented. The intent is only to capture the occurrence of the event and mark the date/time. 1. Press enter to acknowledge the alarm. The system returns to the screen which was in operation when the neutron alarm occurred, which may be the Detect screen (refer to Figure 5 8) or menu screens.

The display continues to show the alarm until the condition is no longer present for the amount of time defined by the Hysteresis setting Neutron Saturation Alarm A Neutron Saturation Alarm is generated by the unit when the neutron detector reaches saturation and the neutron count rate is at the maximum value it can accurately report. The detector can report up to 1.8M cpm, but not above. The neutron detector is not shut off by saturation. After moving away from the source, the count will reduce below the threshold level. Refer to Dose Rate Range on page 2 17 for the neutron gross count. Figure 5-9 Neutron Saturation Alarm Revision B, August Neutron Detection Alarm

150 1. Press enter to acknowledge the alarm. With the alarm acknowledged, the unit returns to the Detect screen. The alarm continues to display at the bottom of the screen until the neutron count falls below the detect threshold level. Figure 5-10 Acknowledged Neutron Saturation Alarm 5.6 Simultaneous Alarms If multiple alarms occur simultaneously, each alarm is acknowledged separately by the user. The highest priority alarm according to Table 5 1 is acknowledged first, followed by the others. Table 5 1 Alert - Alarm Priority Alert / Alarm Condition Alarm Priority Level High Neutron Count (Saturation) 1 High Gamma Dose Rate 2 Threat Radionuclide Identification 3 Neutron Detect 4 Gamma Detection Alert 5 Innocent Radionuclide Identification 6 System Alarm 7 The priority scheme determines which alarm is presented for acknowledgement to the operator when more than one unacknowledged alarms exist. Once the user acknowledges the alarm shown, they are then presented with the next alarm to acknowledge in priority order. Simultaneous Alarms 5 8 Revision B, August 2011

155 Operator s Manual Alerts and Alarms 5.9 Degraded Identification Performance for SNM The system is capable of determining certain circumstances where identification performance for Special Nuclear Materials (SNM) may be degraded; this is accomplished by monitoring the background in specific energy regions of interest. If the system detects SNM at any time during the collection of a spectrum for identification, the RadSeeker CS/CL will inform the operator of this condition on the identification results screen. Figure 5 18 shows the banner Degraded SNM ID performance due to increased gamma signal, which indicates the collected spectrum may cause a reduced ability to identify SNM materials present. Figure 5-18 Degraded SNM ID Performance The ICD file saved as a result of such a collection will contain an indication that the unit was operating in a background that may cause degraded identification performance for SNM. Revision B, August Degraded Identification Performance for SNM

156 5.10 Identification of Low-Level Gamma Signals When analyzing a spectrum for identification, the system will evaluate the gamma spectrum for relative strength over the current background. If the system determines that the signal strength could be marginal for performing identification, the user is notified as shown in Figure Figure 5-19 Signal Weak This notification will occur along with any radionuclides that have been identified. It is an indication that for at least one of the identifications, the signal was considered marginal for making that detection. The user may wish to get closer to the signal source and/or add more time in order to obtain a stronger spectrum for analysis. Identification of Low-Level Gamma Signals 5 14 Revision B, August 2011

157 Operator s Manual Alerts and Alarms 5.11 System Alarms All other alarms fall under the system alarm category. These are alarms generated whenever a fault or error condition exists within the device itself. These alarms range from low memory and low battery charge to failure of either detector or other hardware. Figure 5 20 gives an example of a critically low Battery System Alarm when the remaining battery charge falls below the critically low battery threshold. The RadSeeker CS/CL allows the user to set ʺlowʺ and ʺcritically lowʺ thresholds for remaining battery and memory, using the Advanced Mode configuration menu.

Gamma Alert Level: The general scheme that is used in Geminiʹs gamma alerts is to use the number of gammas observed in a short moving window, in conjunction with a fixed background sample to generate gamma detection alerts to indicate the presence of a source. These thresholds can be represented as a standard deviation. This mapping is shown below: GUI standard deviations 0 Off Neutron Alarm Level: Currently, nine threshold levels are available to the user and they can be mapped to false alarm rate estimates, as shown in the tables below. The following tables, provide a general guide to the false alarm rates that can be expected for three different strength backgrounds with the default detector settings. It should be noted, however, that the specific rates that will be observed in practice will vary with the statistics of the background. Note that the false alarm per day which Revision B, August Adjust Alarm Thresholds

164 is equivalent to 1 in 10 hrs is 2.4. Therefore, in order to achieve a more operationally suitable False Detection Probability (1 in 10 hrs) the threshold level should be set at level 7 to cover the range of backgrounds presented here. The minimum and maximum rates in the tables are the 2.5 percent and 97.5 percent points of the posterior distributions of the mean false alarm rates and represent the uncertainties in the estimates of the mean false alarm rates rather than the actual variability in the false alarm rates themselves.

The factory default is 10 seconds. The hysteresis setting (in seconds) determines the amount of time that an alarm/alert condition must remain below its corresponding threshold before a subsequent alarm/alert of that type can be raised again. For example, with a hysteresis of 10 seconds, after a gamma detection alert occurs, the system must recognize 10 seconds of continuous data below the detect alert threshold before it will recognize another gamma detection alert condition Background Settings Use the Background Settings menu to configure various parameters.

Background Subtraction: Can be enabled or disabled; when enabled, the current background spectrum will be scaled and subtracted from a spectrum collected for identification before being analyzed. Active Background: Can be enabled or disabled; when enabled, the system will continuously evaluate the current gamma environment, determine if the background has changed, and collect a new background as needed. This is all automatic and without user intervention; the user is notified whenever the background has been changed. NOTE: The factory default setting for background collection time is 300 seconds. Background subtraction and Active Background features are both enabled as factory defaults. View Background Spectrum: The RadSeeker maintains an internally stored background spectrum, which is collected automatically by the Active Background function (if enabled), and may also be collected manually by the Collect New Background function. This spectrum is used in the background subtraction process during isotope identification; the neutron count collected during the background collection is used as a baseline for the purpose of detecting neutrons and generate neutron alarms. The background gamma spectrum, and number of neutrons seen during background collection, may be viewed by the View Background Spectrum function. A graph displays number of counts (on the y axis, linear) verses the gamma energy (on the x axis, 0 3MeV range). The amount of real time over which this background was collected is indicated by ʺCollection Time,ʺ and the number of neutron counts seen during this time is indicated by ʺNeutrons.ʺ Adjust Alarm Thresholds 6 8 Revision B, August 2011
