Title: Ultraviolet radiation dosimeter
IPC: G01J1/50
Filed: 1980-12-10
Abstract: A photochemical UV dosimeter has a photosensitive element which has an action spectrum (response vs wavelength) very close to that of human skin in the erythemal (skin reddening) range of the ultra-violet (ie wavelengths below about 320 nm). The preferred photosensitive element in the dosimeter comprises a photosensitive material, especially a polysulphone, particularly dimethyl polysulphone, having an effective thickness of below about 10 microns, preferably below about 1 micron. The photosensitive element may be dispersed in an inert matrix or, preferably, mounted on a non-photoactive support. In either case the preferred material is polyvinylalcohol or regenerated cellulose strip (cellophane Trade Mark). The photochemical response, as read at 302 nm is independent of dose rate, at least from 0.5 to 2.5 J/cm<2>, and of temperature, from -4 DEG  to 50 DEG C, giving A302 of 0.2 for 1J/cm2 of radiation at 280 +/- 0.5 nm. The action spectrum is independent of dose and closely approximates to that of human skin.
