14705 116 ave Edmonton, AbT5m-3E8www.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.

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

Response Time Comparison

Set Up

Dose Rate = 600mR/hr

Distance to Center of Detector = 11.79”D(inches) = 22.2(mCi/mRhr)ˆ½

Activity of reference SourceCs-137, s/n S1307 on October 27, 2008

= 168.88 mCi

Analog

Actually footage taken at IRSS using a Cs-137(NIST Traceable) source with current activity 168.89mCi

Canadian AdmiralModel CCD-100-10S/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

SOR/R OverviewGeneral 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

SOR/R OverviewGeneral 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

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

Display Messages – Internal Faults

Defective Detector:Remove from serviceReturn 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 for72 hrs,reinstall

Defective Calibration:Calibration data integrityproblem; re-calibrate dosimeter

Defective Componentfor 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. ContactMGPI for help

Drained Battery:Remove battery for 72 hrs; inspect for damage

History

Customizable Alarm/Alarm Warning ThresholdsAudible Alarms and Warnings Have Different Tone

HistoryTime 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 secondsRecords can be electronically saved or printed
