X-RAY RECORDING MATERIAL, METHOD FOR PRODUCING X-RAY RECORDING MATERIAL, X-RAY RECORDING MEDIUM, RECORDING METHOD USING X-RAY RECORDING MEDIUM, AND METHOD OF MEASURING X-RAY IRRADIANCE

摘要

PROBLEM TO BE SOLVED: To provide an X-ray recording material that can be used repeatedly and has durability, featuring excellent practical utility, a method for producing the X-ray recording material, an X-ray recording medium, a recording method using the X-ray recording medium, and a method of measuring an X-ray irradiance.SOLUTION: A photochromic material, which is an X-ray recording material of the present invention, has a composition represented by the following formula (a): Ba(MgFeAl)(SiB) O(where 0≤x0.01, 0≤y0.10, 0≤z0.20). The material is based on a barium magnesium silicate having a skeleton of SiO-MgOnetwork structure.SELECTED DRAWING: Figure 1
