Document Type and Number:
WIPO Patent Application WO/2019/069853
Kind Code:
A1
Abstract:
[Problem] To provide a radiation dosimetry sol or gel and a radiation dosimeter using the same as a material for radiation dosimetry. [Solution] A radiation dosimetry sol or gel characterized by including a compound (A) having a fluorescence characteristic in response to excitation light that is changed by a radiolysis product of water, and a silicate (B). A radiation dosimetry sol or gel including a compound (A) having a fluorescence characteristic in response to excitation light that is changed by a radiolysis product of water, a silicate (B), a water-soluble organic polymer (C) having an organic acid salt structure or organic acid anion structure, and a dispersant (D) for the silicate (B). A radiation dosimeter comprising the radiation dosimetry sol or gel as a material for radiation dosimetry.
