Radiation dosimetry sol or gel and radiation dosimeter comprising same as material for radiation dosimetry

Abstract

A radiation dosimetry sol or gel, and a radiation dosimeter containing the sol or the gel as a material for radiation dosimetry. A radiation dosimetry sol or gel including a compound (A) having an excitation light-induced fluorescence property that is changed by a radiolysis product of water; and a silicate salt (B). A radiation dosimetry sol or gel including a compound (A) having an excitation light-induced fluorescence property that is changed by a radiolysis product of water; a silicate salt (B); a water-soluble organic polymer (C) having an organic acid salt structure or an organic acid anion structure; and a dispersant (D) for the silicate salt (B). A radiation dosimeter including, as a material for radiation dosimetry, the above-mentioned radiation dosimetry sol or gel.
