RADIATION-SENSITIVE COMPOSITION AND DOSIMETER

摘要

PROBLEM TO BE SOLVED: To provide a radiation-sensitive composition usable for detecting radiations and making dose measurements in high accuracy. SOLUTION: This radiation-sensitive composition essentially comprises a thermoirreversible photochromic compound and a compound having condensed polycyclic aromatic structure; wherein the latter compound is preferably a high-molecular compound having condensed polycyclic aromatic structure on the side chain, especially a vinyl polymer, and the thermoirreversible photochromic compound is preferably a diarylethene-based compound. The other objective dosimeter using the above composition is also provided.
