GEL DOSEMETER FOR RADIATION DOSE MEASUREMENT AND MANUFACTURING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a gel dosemeter for measuring three dimensional dose distribution.SOLUTION: The gel dosemeter for radiation dose measurement is prepared including: water which is solvent or dispersion medium; clay fine particles swelling with water; and a recording substance precursors, which are solved or dispersed each other. The recording substance precursor contains atoms or ions which reacts with radicals of anyone generated by being ionized from water by irradiation of radiation and molecular radical inducing substance as a molecular generated by radicals combining with each other and changes atomicity. Before being irradiated with radiation, no substance identical to the molecular radical inducing substance remains in the gel dosemeter and has no flowability.
