DOSIMETER FOR CONTROLLING INDIVIDUAL EXPOSURE

摘要

PURPOSE:To mount a dosimeter on a local part such as a finger by welding a heat luminescence material to a heat-resistant synthetic resin film such as a polyimide resin film through a humidity-resistant and heat-resistant specific copolymer film and providing a dosimeter discrimination part thereon. CONSTITUTION:A perfluoroalkyl vinyl ether copolymer (PFA) film 2 excellent in humidity resistance and heat resistance is thermally welded to a polyimide film or other heat-resistant synthetic resin film 1. A circular heat luminescence material 4 being a radiation responsive material can measure an effective dose equivalent in the thickness of about 70 mum under the surface of the skin using a bio-equivalent Li2B4O7 phosphor and protected by surrounding the periphery thereof by a metal plate 3 and thermally welded to the film 2. a PFA 5 is coated with the material 4 and a bar code or other discriminable number is printed on a dosimeter discrimination part 6. The thickness of the metal plate 4 and other part becoming the shield of the material 4 is set to about 10 - 20 mum and the film 2 is welded on the film 1 to make it possible to mount a dosimeter on a finger.
