The RADView™ CT dosimeter badge is smaller than a credit card radiation dosimeter incorporating a self-developing radio chromic 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™ CT 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™ CT can be read visually after a CT scan. Most users would be able to visually estimate the dose to within ±20%. The visual read out does not require darkroom or processing equipment.
International Specialty Products (ISP) holds numerous patents (U.S. Pat. 5,731,112 and others) on the chemical technology and design elements of RADView™ PD dosimeters. Originally developed for the medical industry, the active component in the dosimeter is a micro particulate, radiation sensitive diacetylene monomer dispersed in a polymer matrix and applied to a polyester film base. When the active monomer is exposed to ionizing radiation, a polymerization reaction immediately produces an intensely colored dye polymer that changes the appearance of the dosimeter. The amount of dye produced is proportional to the radiation dose. The dye polymer is cyan blue with a major absorbance peak at 635 nm and a minor peak at 585 nm and appears gray on the badge under the UV filter. The dosimeter will tolerate intermittent UV exposure and temperatures up to 130°F.
Quantity discounts are available for hospitals, clinics, doctors, and insurance companies. RADeCO, a veteran-owned small business, is the worldwide distributor for RADView™ CT dosimeters. More accurate Laboratory read outs and dose evaluations can be provided by the manufacturer, ISP Inc.
