A plastic radiation indicator consisting of a chlorinecontaining polymer and an acid-sensitive dye which changes colors in the solid state according to the variation of pH in the acid region. The chlorine-containing polymer releases hydrogen chloride due to excitation by the radiation irradiated to the polymer, the hydrogen chloride thus released changes the color of the dye present. Since the changes of color correspond to the irradited doses, the radiation indicator can be used in dosimetry. |
