ラマン分光法によるナトリウム鉄複合酸化物の化学的同定法を利用して高温での過酸化ナトリウムによる鉄の腐食反応のその場観察を試みて、その適用性を調べるとともに、腐食の進行による生成物の時間変化と同定を行った。

Focusing on the cover layer materials (as the Radon Barrier Materials), which could have the effect to restrain the radon from scattering into the air and the effect of the radiation shielding, we produced the radon barrier materials with crude bentonite on an experimental basis, using the rotary type comprehensive unit for grinding and mixing, through which we carried out the evaluation of the characteristics thereof.
