Page 92: Calibrating The System
Appendix A Calibrating the System A. Calibrating the System The iMatic system, like any precision analytical instrument, must be calibrated in order to measure samples with accurate, precise, and reproducible results. The iMatic has features that make calibration easy to set up and repeat. With dedicated calibration procedures, the system can be set up quickly and calibration repeated easily with minimal impact on productivity.

Page 98: Counting Samples
Appendix B Counting Samples B. Counting Samples The primary function of the iMatic is to count user samples and provide accurate alpha and beta results that are Radon and Thoron corrected. In order to count samples accurately and correctly the system must be properly calibrated and procedures must be created that provide the sensitivity requirements of the sample to be analyzed.
Page 99: System Qc Charts
QC Chart Reference C. System QC Charts The iMatic includes a versatile QC Charting function that allows background and efficiency QC information to be tracked over time. The QC Chart features a 90-point moving-window that allows multiple-points-per-day to be included in the chart. The Printer Setup default is 90 characters per line to allow the time-of-day to be included for each measurement.
Page 100: Qc Lockout
Appendix C System QC Charts QC Lockout The QC Lockout feature allows the system to apply a simple test to the Daily Background, Alpha Efficiency, and Beta Efficiency to disable (lockout) the system if results exceed acceptance limits. The QC Lockout feature compares the daily measurement to the QC chart reference parameter.
Page 101: Optimizing The Canberra Iseries For Air Sample Counting
The CANBERRA iSERIES algorithm is discussed in Mirion Technologies (Canberra) literature. An entire algorithm manual is available from Mirion Technologies (Canberra) (part number 9237566). This appendix will not discuss the details of the algorithm in detail beyond what is required to optimize the results. The steps performed by the algorithm are summarized below: 1.
Page 102: Testing The Algorithm
Appendix D Optimizing the CANBERRA iSERIES for Air Sample Counting Testing the Algorithm The recommended testing method is to use real samples that have been collected in the normal manner. A longitudinal study should be conducted on each sample to determine that the activity value observed prior to the radon and/or thoron decay is statistically equivalent to the results after the radon and/or thoron has decayed.
Page 103: Gain Calibration
Figure 6 Transuranic Peaks and Radon Progeny Gain Calibration The CANBERRA iSERIES is shipped from the factory with the system gain calibration having been performed. The gain is set at the factory using an Am-241 radioactive standard source physically identical to the AM50MM available from Mirion Technologies (Canberra).
Page 104 Appendix D Optimizing the CANBERRA iSERIES for Air Sample Counting The GAIN Calibration should only be necessary in the event of: • Change of Hardware • System Master Clear with no restorable personality file available • Radon compensation issues not resolved following the recommendations...
Page 105: Analysis Calibrations
iSERIES Algorithm When performing a GAIN calibration it is crucial that the active face of the standard is exactly 4 mm from the front of the detector. Most “planchet” type standard sources cannot be placed with the active area in the proper location. When using the SH-CAL holder shown in Figure 9 (iSOLO) or the IS-CAL shown in Figure 10 (iMATIC) the AM50MM standard will be placed exactly the correct distance from the detector.
Page 106: Sample Distance
Appendix D Optimizing the CANBERRA iSERIES for Air Sample Counting For the most accurate results, users should obtain standard sources that are as much like the sample collection media as possible. If efficiency standard sources that are unlike the samples in physical makeup or contains radioactive isotopes unlike those likely to be found the sample, a systematic bias will be introduced to the results.

(Po-218) has energy of 6.0 MeV with half-life of 3.05 minutes. Mirion Technologies (Canberra) recommends aging each sample for 10 minutes prior to the start of the first analysis. Practically speaking, this limitation may only apply if the full alpha (Cm-242, Cm-244) region is being used but the recommendation still holds for the other regions as well.
Page 108: Sample Collection Time
Appendix D Optimizing the CANBERRA iSERIES for Air Sample Counting Sample Collection Time Air samples are typically collected for as little as a few minutes to as much as several days. As stated earlier in this application note, early versions of the algorithm assumed that the Thoron progeny (ThC and ThC') were present if the Radon progeny (RaC') existed.

Page 110: Filter Media Selection
Appendix D Optimizing the CANBERRA iSERIES for Air Sample Counting Figure 15 1 Hour PTFE Sample 10 Minutes After Collection Users should be cognizant of the fact that different collection times will yield different responses due to influences. Longer collection times tend to have a higher ratio of thoron progeny to radon progeny until the point at which thoron equilibrium is reached.
Page 111 iSERIES Algorithm Figure 16 One Hour Glass Fiber Filter The activity results show a dramatic difference as well. Table 2 shows the difference in the activity of the compensated results using the two filters. Not only is there a huge difference in the alpha results, but the low tailing of the alpha falling into the beta channel is significant as well.
Page 112: Regions
Appendix D Optimizing the CANBERRA iSERIES for Air Sample Counting In reviewing a recent user's actual field results using a glass fiber filter, the algorithm correctly compensated for 95%+ alpha interference and 90%+ beta interference. Regions Another way to improve the compensated results is to use the alpha region most closely resembling nuclides expected to be found in any contaminated sample.

Page 114 Appendix D Optimizing the CANBERRA iSERIES for Air Sample Counting Figure 17 Incorrect Results with Improper Gain Cal It sometimes happens that a facility is aware that the gain calibration is set incorrectly for their standards, yet they do not possess a proper Am-241 standard to perform a new gain calibration.

Installation of Unit Installing the Detector The iMatic PIPS detector normally installed into the PIPS detector mounting assembly at the factory. The detector should not be removed from the mounting assembly needlessly because of the potential to damage the detector and mounting assembly during installation.
Page 138 Appendix F System Installation Step 2 Carefully open the PIPS detector shipping box and remove the detector being careful not to let the detector slide out of the protective cap. Screw the detector onto the detector installation base by rotating the detector clockwise. Set the base/detector assembly on a sturdy flat surface and remove the protective cap from the PIPS detector.
