Direct Reading Dosimeters

Arrow-Tech dosimeters are rugged, precision instruments about the size of a pocket fountain pen, which are used to measure accumulative doses or quantities of gamma & X-ray radiation. A metal clip is used to attach the dosimeter to an individual's pocket or to any available object in an area to be monitored for total radiation exposure.
It is a conductive-fiber electroscope with an ion chamber for detecting and indication integrated exposure to gamma and x-radiation. It has a thin wall which permits the penetration and detection of radiation.

Specifications: Radiation Detected: Gamma and X-ray from 16 KeV to 6 MeV. Ranges: 0 - 200 mR to 0 - 600 R. Detector: Fiber electrometer mounted in an electrically conducting plastic ion chamber. Detector Housing: Very low permeability plastics - hermetically sealed. Accuracy: Within + or - 10% of true exposure.
Rate Response: Dose rate independent for gamma and x-radiation. Electrical Leakage: Less than 0.5% of full scale for 24 hours at 50 degrees C. Temperature Range: -20 degrees C to 50 degrees C. Relative Humidity: Up to 90%. Dimensions: Length 4.5 in. (12.4cm), Diameter: 0.6in (1.5cm). Weight: 1.0 oz. (25 grams)
Finish: Barrell and end caps: Natural matte black. Clips: Metal clips. Warranty: 2 year limited warranty. ANSI Spec: Manufactured to ANSI N322-1997 N13.5.

 If your Dosimeter is going to be used in harsh conditions where scratching of the lens is a concern we recommend a synthetic sapphire window to protect the lens even in the toughest of conditions. The Dosimeter may be zeroed with any of our dosimeter chargers. Calibration Certification Document included.
