The use of (229)Th as tracer has become generalised for determination of naturally occurring alpha-emitting thorium isotopes. This paper describes two procedures that allow standardising (229)Th solutions of the order of Bq/g without the need of radiochemical separation of its daughters.
将(229)钍用作示踪剂已被广泛用于测定天然存在的发射α粒子的钍同位素。本文描述了两种方法,可在无需对其子体进行放射化学分离的情况下,对Bq/g量级的(229)钍溶液进行标准化。
