Dosimeter for Gamma and X radiation
The advanced PEN direct reading dosimeter is rugged, precision instrument
It is higher quality and has greater reliability than other dosimeters of this type
It measure and directly read, at any time, accumulated dose (quantity of gamma and x-ray exposure)
It is designed to satisfy military specifications IM-264/PD and ANSI N 13.5 and N322 requirements
A sturdy metal clip attaches the dosimeter to a pocket or any object to monitor total radiation exposure
It is hermetically sealed and immersion proof
Specifications: Exposure Range (gamma and x-rays)
Scale increments of 10mR 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 dosimeter leakage or self discharge is less than 0.5% of full scale in 24 hours at 50° C
At 20° C dosimeter 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: Dosimeter is 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:
i) Temperature range below -20°C (-4°F) or above +50°C (122°F)
ii) Greater than 50,000 foot altitude for one month
iii) 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: Dosimeter is dose rate independent
Enclosure Material: Barrel - carbon fiber-filled, high-strength, electrically-conducting plastic with metal clip
Weight: 19 grams
Size: Length: 11 cm Diameter: 1.5 cm
MADE IN USA
