SE International PEN5mSv 펜형 선량계 (increments of .2mSv)

Exposure Range (gamma and x-rays):  increments of 2mSv

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 Cs137 or Co60 gamma.

Rate Response: Dosimeters are dose rate independent.

Enclosure Material: Barrel - carbon fiber-filled, high-strength, electrically-conducting plastic with metal clip.

Weight: Approx. 19 grams (0.7 oz.)
