2. About IRSS 14705 116 ave Edmonton, Ab T5m-3E8 www.irss.ca Industrial Radiography Supplies and Services Inc. (IR), located in Edmonton Alberta, Canada, is in its first years of operations and has become the leading supplier of RT products in Western Canada. IR’s vision for the future will be to expand into other NDE disciplines and develop an educational center focusing on radiation safety and product training. IR will also become a leader in digital technology working with those companies that are willing to help us develop products that will perform under Western Canada’s unique climate and production techniques.

5. Different models have Different Ranges and are displayed using different scales Digital models have an easy to read display that goes from 0.1mR to 1000R and can with the push of a button can even display the rate as a double check to a survey meter Dosimeter Displays

6. Response Time Comparison

7. Set Up Dose Rate = 600mR/hr Distance to Center of Detector = 11.79” D(inches) = 22.2(mCi/mRhr)ˆ½ Activity of reference Source Cs-137, s/n S1307 on October 27, 2008 = 168.88 mCi

8. Analog Actually footage taken at IRSS using a Cs-137 (NIST Traceable) source with current activity 168.89mCi Canadian Admiral Model CCD-100-10 S/N 02085 Display not scaled with proportional increments, makes it hard to read current field strength at a glance Jumps between 500mR/hr and 700mR/hr Meter set on high scale If on low, the scale range would have to be changed manually by the user

9. Digital Actually footage taken at IRSS using a Cs-137 (NIST Traceable) source with current activity 168.89mCi RDS 30 S/N 270700 Scale range is automatic and requires no user intervention Display easily read Stable Field Measurement

15. SOR/R Overview General Features Solid State (silicon diode) detector Personnel & Area Monitoring capability Linear response to 1000 R/hr Energy Range: 50 keV - 6 MeV Self Testing/Diagnostics (battery, detector) Internal Memory “Histogram” Standard Calculator Battery - over 2000 hrs Multi-Configuration: - Dose, Rate and Time Alarm/Warning - Satellite or Autonomous operation - Hands-Free communication

16. SOR/R Overview General Features Alarm Thresholds - Primary Alarm for Dose and Dose Rate - Pre-Alarms (warnings) for Dose and Dose Rate Histogram – “Events History” - 700 intervals - 10 sec, 1 min, 10 min, 1 hr, 24 hr - Stamps dose increment, date, time at selected time interval; records alarm or error indication automatically

17. SOR/R Overview General Features Optical Detector Check - Expose diode to light source every 10 minutes - Three consecutive failures, detector fault alarm (def det)  Test-to-failure concept! Background Radiation check - 10 uR/hr: one pulse ~ 10 minutes - No counts in pre-determined time: det. Fault Battery (voltage)check every 10 minutes

18. Display Messages – Internal Faults Defective Detector: Remove from service Return for repair/replacement Defective History: Start new histogram using Reader – Entry/Exit Defective Battery: Battery discharged/removed; Change battery, check for short Or defective ground wire Defective EEPROM: Problem accessing data in Memory; remove battery for 72 hrs,reinstall Defective Calibration: Calibration data integrity problem; re-calibrate dosimeter Defective Component for Pulse Counting: Remove from service; return For repair/replacement Defective External Detector/Initialization: External detector calibration value corrupted; Data integrity suspect or corrupted; re- initialize calibration or system parameters. Contact MGPI for help Drained Battery: Remove battery for 72 hrs; inspect for damage

19. History Customizable Alarm/Alarm Warning Thresholds Audible Alarms and Warnings Have Different Tone History Time Stamp- Can be set to record down to an interval of every 10 seconds Detailed Graph- allows user to display and calculate dose increments down to an interval of every 10 seconds Records can be electronically saved or printed Dose and Dose Rate thresholds Have Different Audible Tones

20. New Designs to meet user preferences and demands New Technology can be used in traditional designs In Development

21. ALARA and Safety Advantages Digital Dosimeters display instantaneous, easy to read and accurate dose levels Digital Survey Meters do not need to be adjusted by the user to change scales Digital Survey Meters Digital Dosimeters Digital Dosimeter History reports can be analyzed, saved electronically, and matched to TLD reports Customizable audible alarm thresholds Have a scale going up too 1000R, Dose will not run meter off scale
