Direct Reading Pocket Dosimeters
Model 138 shown
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.
Dosimeters are extremely sensitive instruments. Although they are constructed for rugged use, they should receive the same care as a wristwatch. Since dosimeters are hermetically sealed at the factory, they cannot be repaired or adjusted in the field. Therefore, if instrument malfunctioning is experienced, the instrument should be returned to the factory or your dealer.
Dosimeters may be maintained in operating condition simply by cleaning the eyepiece lens and the charging switch insulator with clean water and a cloth that is free of lint and grit. Make sure the charging switch insulator is absolutely free of lint and moisture at all times.
Caution: Do not insert any sharp objects into, or tamper with parts in the charging switch recess. Irreparable damage may be done.
We recommend a yearly calibration of the Direct-Reading Dosimeter which is generally consistent with good health physics practices. More frequent calibration may be necessary should the user’s license require a shorter calibration.
The Direct-Reading Dosimeter is a pocket-sized instrument used to measure x-ray and gamma exposure.

needed in harsh environments to prevent scratching of the lens.Our instruments do not contain any radiation sources, they detect
radiation only.
