The advanced PEN direct reading dosimeters are rugged, precision instruments. They are higher quality and have greater reliability than other dosimeters of this type. They measure and directly read, at any time, accumulated dose (quantity of gamma and x-ray exposure). PEN dosimeters are designed to satisfy military specifications for the RADIAC METER 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. They are hermetically sealed and immersion proof.

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.

Dosi-Lite for Pen Dosimeters

The Dosi-Lite provides illumination for a Direct-Reading Dosimeter in low light conditions which is held directly in front of the eye for viewing. The Dosi-Lite comprises of a light-emitting diode (LED) enclosed in a thimble-shaped flexible plastic casing, which slides onto the end of a dosimeter. When the user squeezes the casing, the leads are brought into contact with the batteries, thereby completing the circuit, lighting the LED, and illuminating the Direct-Reading Dosimeter.

The Dosi-Lite

The Dosi-Lite is designed for personnel that spend extended periods in areas with lighting which is insufficient or inconvenient for reading the Direct-Reading Dosimeter, thus running the risk of being exposed to excessive radiation before taking the next reading. The Dosi-Lite provides a convenient illuminating device for Direct-Reading Dosimeters that fits onto the end of a Direct-Reading Dosimeter.

The Charger for Pen Dosimeters

The Charger

The patented, handheld Charger can charge a variety of direct-reading dosimeters by simply squeezing the lever of a generator. The Charger requires no batteries. By
pulling a trigger, a dosimeter is easily placed in or removed from the charger. The
clamping action holds the dosimeter for you. NSN# 6665-00-856-8813 - CD V-750
