| SPECIFICATIONS |
| Exposure Range |
- PEN200 : 0 to 200mR (gamma and x-rays).
- PEN5 : 0 to 5R (gamma and x-rays).
|
| Accuracy |
±10% of true dose for Cs-137 or Co-60 gamma. |
| Energy Dependence |
- PEN200 : ±10% maximum change in sensitivity for x and
gamma ray energies from 30 keV to 1.25 MeV.
- PEN5 : ±10% maximum change in sensitivity for x and
gamma ray energies from 30 keV to 2 MeV.
|
| Rate Response |
Dosimeters are dose rate independent. |
| Electrical Leakage |
In the absence of radiation, the dosimeters
leakage or self discharge is less than 0.5% of full scale in 24 hours at
50°C. At 20°C dosimeters will read background radiation. After gross over
exposure totaling up to 2000 R the 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. |
| Weight |
Approx. 19 grams (0.7 oz.) |
