Abstract
A personal radiation dosemeter comprising a radiation detector means coupled to an electronic measurement circuit arranged in combination therewith to generate signals representative of an amount of radiation detected by the radiation detector. The radiation detector means is arranged to be screened from ambient light and is further provided with a light source optically coupled to the radiation detector and arranged to operate under control of a test control circuit to generate light of a wavelength which may be detected by said radiation detector. This arrangement provides, in combination with said electronic measurement circuit an integrity test for said radiation detector means.
