DOSIMETER |
|
|
Model: |
PEN200mR, scale increments of 10mR (manufacturer: SE International, Inc.) |
|
|
- Direct reading dosimeter, rugged precision instrument.
- Designed to satisfy RADIAC METER IM-264/PD, ANSI N 13.5 and N322 requirements.
- Metal clip attaches the dosimeter to a pocket or an object to monitor the total radiation exposure.
- Hermetically sealed and immersion-proof. |
|
Materials: |
Barrel: carbon-fibre-filled, and made of high-strength electrically-conducting plastic with a metal clip. |
|
Size: |
Length: 11cm, diameter: 1.5cm, weight: approximately 19g |
|
Specifications: |
- Energy dependence ±10% maximum change in sensitivity for X and gamma ray energies from 16keV to 8MeV. |
|
|
- Electrical leakage: In the absence of radiation, the dosimeter’s leakage or self-discharge is less than 0.5% of full scale in 24 hours at 50°C. At 20°C, dosimeters will also read background radiation. |
|
|
After a gross overexposure, totalling up to 2000R, leakage is less than 5% of full scale in 48 hours at 20°C. Thereafter, the leakage will decrease to original values. |
|
. |
- Charging voltage: dosimeters are capable of being charged to "zero" with 140 to 195 volts. |
|
Operational Characteristics: |
A maximum ±10% change in sensitivity may occur under any combination of the following: |
|
|
A) Temperatures below -20°C or above +50°C |
|
|
B) Altitudes greater than 50,000 feet, for one month. |
|
|
C) Relative humidity greater than 95%. |
|
|
- Highly resistant to shock and vibrations. |
|
|
- Accuracy: ±10% of true dose for Cs-137 or Co-60 gamma. |
|
|
- Rate response: dosimeters are dose rate independent. |
|
|
-Warranty: 2 years |
