Beschreibung
Zusammenfassung:	This invention relates to radiation indicators (10) which indicate the exposure of an electrical component (12) to ultra-violet (u.v.) radiation (11). With reference to Figure 1, a radiation indicator (10), comprising means receptive to incident ultra-violet radiation of energy greater than a predetermined threshold energy (Ethres), is coupled to an electrical component (12) susceptible to malfunction from the effects of said radiation. The means receptive to said radiation visibly changes (14) in some way in response to the radiation and indicates a likelihood that the device will malfunction.
