描述
Exposure Range (gamma and x-rays)
Energy Dependence:
±10% maximum change in sensitivity for x and gamma ray energies from 16 keV to 8 MeV.
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.
Operational Characteristics
A maximum change in sensitivity of ±10% may occur under any probable combination of the following:
A) Temperature range below -20°C (-4°F) or above +50°C (122°F)
B) Greater than 50,000 foot altitude for one month
C) Relative humidity greater than 95% Highly resistant to shock and vibration.Accuracy
±10% of true dose for Cs-137 or Co-60 gamma.
Rate Response
Dosimeters are dose rate independent.
