Abstract
Ionising radiation dosimeter comprising a flexible support coated with a colourless tetrazolium salt (I) which yields a formazane dye on exposure, in a binder. (I) is pref. of formula nwhere R2 and R3 are each aryl or heterocyclic gps. R' is H, alkyl, aryl, heterocyclic gp. OH, COOH, SO3H, SH or NO2 pref. R' and R2 and R3 are all phenyl Y is an anion pref. Cr-). Binder may be gelatin, PVA, cellulose acetobutyrate, or polyvinyl pyrolidone; support is pref. cellulose triacetate or polyethylene terephthalate.
