摘要： A gel forming composition for radiation dosimetry, and a high sensitivity and high safety radiation dosimeter using a gel formed from the composition. A gel forming composition for radiation dosimetry comprising a gelator and a compound of Formula (1): (wherein R1 is a hydrogen atom, a halogen atom, an optionally substituted C1-12 alkyl group, etc.; and R2 and R3 are each independently a hydrogen atom, an optionally substituted C1-12 alkyl group, an optionally substituted monovalent C6-12 aromatic group, or R2 and R3 form a 4- to 8-membered ring together with a carbon atom to which R2 and R3 are bonded, and the 4-to 8-membered ring may have 0 to 3 nitrogen atoms, oxygen atoms, or sulfur atoms as a ring atom, provided that R2 and R3 are not simultaneously a hydrogen atom).

摘要： To measure three-dimensional dose distributions with a dosimeter, such as a gel dosimeter. In an embodiment of the present invention, provided is a gel dosimeter having water, as solvent or disperse medium, clay particles that swell with water, and recording material precursor, which are dissolved or dispersed with each other. The recording material precursor has an atom or ion, wherein the atom or ion changes its valence number by reacting with both of a radical and a molecular radical derivative. The radical is to be generated from the water ionized by irradiation of radiation rays, and the molecular radical derivative is a molecule to be formed by bonding the radicals with each other. By the time radiation rays are irradiated, the gel dosimeter has been free from a substance identical to the molecular radical derivative and has lost fluidity.
