Features & Applications:
The Radiation Alert Pen Dosimeter is a rugged, precision instrument. It is higher quality and has greater reliability than other dosimeter of this type. It measures and directly reads accumulated dose (quantity of gamma and x-ray exposure). It is 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. It is hermetically sealed and immersion proof.
Features:
Spec Summary:
|
Exposure Range (Gamma and
X-rays):
|
0-200 mR
|
|
Energy Dependence:
|
±10% maximum change in sensitivity for
x and gamma ray energies from 30 keV to 1.25 MeV
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 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
