Abstract:
1. A gel dosimeter for measuring radiation dose comprising: water, as solvent or disperse medium: clay particles; recording material precursor having an atom or ion, wherein the atom or ion changes a valence number by reacting with both of a radical and a molecular radical derivative the radical being any of radicals to be generated from the water ionized by irradiation with radiation rays, and the molecular radical derivative being a molecule to be formed from the radicals that are bonded with each other; and a radical derivative blocking substance, wherein the radical derivative blocking substance prevents a substance identical to the molecular radical derivative from remaining, wherein the water, the clay particles, and the recording material precursor are dissolved or dispersed with each other, wherein the gel dosimeter is free from a substance identical to the molecular radical derivative before being irradiated with radiation rays, wherein the gel dosimeter ha lost fluidity by the time irradiation with radiation rays occurs, wherein the molecular radical derivative is oxygen, and wherein the radical derivative blocking substance is a gas that does not contain oxygen.
