Title:
酸化ベリリウム及び／又は四ホウ酸リチウムの使用によって体組織に近い実効原子番号を有する、自由中性子を検出するための複合材料；線量計；自由中性子を捕獲又は検出する方法
Document Type and Number:
Japanese Patent JP7066819
Kind Code:
B2
Abstract:
A method as well as a composite material for detecting free neutrons are disclosed that include a converter material, which is configured to generate in response to a capture of neutrons a secondary radiation, and a detector material, which is configured to store an information relating to the secondary radiation and to release it again in a later evaluation by optically stimulated luminance. The converter material and the detector material each are present in a plurality of particles, which are jointly present in the composite material as material mixture. In order to improve the detection of neutrons with regard to a person dosimetry, that is the estimation of a dose absorbed by a human, it is envisaged that the detector material is formed from beryllium oxide and/or the converter material is formed from lithium tetraborate.
