SINQ照射材に残留するHとHeの測定を異なる方法で実施した結果、Heの測定値は異なる測定方法の間でファクター2以内の残留量を得た。TEM材の測定では、既報データと比べて数10パーセントの範囲で検量された。水素の測定値は誤差の範囲であり、有為な値を示すことはできなかった。

Residual hydrogen and helium gases in the materials irradiated in SINQ were measured by two different methods. The results showed that the amount of residual helium gas was within a factor two. For the case of TEM specimens the residual helium gas was scattered within a couple of tens percent in comparison with published data. Residual hydrogen could not be quantified because of measuring accuracy.
