ABSTRACT:
Radiation-sensitive material for use in dosimetry comprises a matrix base, an acid-sensitive dye such as dimethyl yellow, and a halogen-containing substance, the material being capable of producing a halo-acid upon radiolysis. The matrix base is a solid polymer such as poly(methyl methacrylate) and the halogen-containing substance is a solid in which the polymer is insoluble such as hexachloroethane so that the radiation-sensitive material is a solid, self-supporting plastics material.
