ホウケイ酸ガラスの中性子照射による影響を調査するため、中性子照射後のガラス試料をラマン分光測定及び放射光XAFS測定により評価した。その結果、照射によってSi-O架橋構造や含有元素原子価が変化することを確認した。

To investigate the characterization damage of a borosilicate glass by a neutron irradiation, the glass sample after neutron irradiation was estimated by using the Raman spectrophotometry and the synchrotron XAFS measurement. As a result, we confirmed that the Si-O bridge structure of a borosilicate glass and the containing element valence in the glass were changed by the neutron irradiation.
