The Radiation Alert Pen Dosimeter is a rugged, precision instrument. It is higher quality and has greater reliability than other dosimeters 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.
| 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
