Instant Radiation Exposure Detection
The RADView™ PD dosimeter badge from GDS, is a credit card size radiation dosimeter incorporating a self-developing radiochromic film to provide visual measurement of absorbed radiation dose. The film develops a distinctive and characteristic color upon exposure to ionizing radiation, becoming progressively darker in proportion to absorbed dose.
RADView PD dosimeters are unaffected by brief exposures to sunlight or normal room light. The films are water resistant, tissue equivalent, energy independent and dose-rate independent. The badges do not require calibration or maintenance, have no electronics or batteries, and are small and light. The RADView PD can be read visually by the wearer at the incident scene.
Accuracy is within 5% and combined accuracy and precision is within 10% in testing performed with a National Institute of Standards and Technologies (NIST) traceable calibration facility. The visual readout does not require darkroom or processing equipment.
Under most conditions, the dosimeter can be worn for one year before replacement. A quick visual observation of a RADView PD dosimeter allows anyone to assess the absorbed dose.
