daughter nuclidesとは 意味・読み方・使い方

To quantitate α-ray emitting nuclides included in a sample extracted from radioactive wastes or the like, the thickness of the measuring sample is set to be sufficiently larger than the range of α-rays, and Rn gas and its daughter nuclide are confined to be within the sample as a solid α-ray measuring sample, in which α-rays emission nuclides are uniformly distributed.例文帳に追加

放射性廃棄物等から採取した試料に含まれるα線放出核種を定量するために、測定用試料厚さをα線の飛程に比べて十分に厚くし、α線放出核種が均一に分布した固体状のα線測定用試料として、試料内部にＲｎガスおよびその娘核種を閉じ込めるようにする。 - 特許庁
