The Direct-Reading Dosimeters are rugged, precision instruments. They are designed to measure and directly read, at any time accumulated dose of gamma and x-ray radiation exposure. The Direct-Reading Dosimeter is designed to satisfy military specifications for the IM-Series RADIAC METER and ANSI N13.5 and N322 requirements. The sturdy metal clip attaches the dosimeter to a pocket or any object to monitor total radiation exposure. They are hermetically-sealed and immersion proof. The Direct-Reading Dosimeter is a pocket-size, carbon-fiber electroscope with an ion chamber for detecting and indication of integrated exposure to Gamma and X-Ray radiation. It has a thin wall which permits the penetration and detection of radiation. This model comes with a hardened sapphire window that won't scratch even in the toughest of conditions.
