The advanced PEN direct reading dosimeters are rugged, precision instruments. The quality and reliability are greatly improved over other dosimeters of this type. They measure and directly read, at any time, accumulated dose or quantity of gamma and x-ray exposure. A sturdy metal clip attaches the dosimeter to a pocket or any object to monitor for total radiation exposure. They are hermetically sealed and immersion proof.
Dosimeters are dose rate independent.
At 20 C dosimeters will read background radiation. 20 C. Thereafter, the leakage will decrease to original values. Highly resistant to shock and vibration.
