…On the other hand, stable isotopes can also be used as tracers, in which case they are called stable isotope tracers. When large amounts of radioactive tracers are required, experiments can be difficult and dangerous to prevent radiation damage, so stable isotopes are used as tracers, and samples containing the tracer are collected during the experiment, and then activated to determine the amount of tracer, in which case they are called activatable tracers. Tracers can be used in two ways: physical tracers and chemical tracers. … *Some of the terminology that mentions "activable tracer" is listed below.

…一方,安定同位体をトレーサーとして使用することもあり,この場合は安定同位体トレーサーと呼ばれる。大量の放射性トレーサー使用を必要とする場合には,放射線障害防止のため実験が困難となり危険も伴うので,安定同位体をトレーサーとして使用し,実験中にトレーサーを含む試料を採取した後,これを放射化してトレーサー量を決定する場合があり,アクチバブル・トレーサーと呼ばれる。 トレーサーの利用法は,物理的トレーサーと化学的トレーサーに大別することができる。… ※「アクチバブル・トレーサー」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
