Extensive studies on transfer of radionuclides to animals were carried out in the USSR from the 1950s. Few of these studies were published in the international refereed literature or taken into account in international reviews. This paper continues a series of reviews of Russian language literature on radionuclide transfer to animals, providing information on biological half-lives of radionuclides in various animal tissues. The data are compared, where possible, with those reported in other countries. The data are normally quantified using a single or double exponential accounting for different proportions of the loss. For some products, such as milk, biological half-lives tend to be rapid at 1-3 d for most radionuclides and largely described by a single exponential. However, for other animal products biological half-lives can vary widely as they are influenced by many factors such as the age and size of the animal. Experimental protocols, such as the duration of the study, radionuclide administration and/or sample collection protocol also influence the value of biological half-lives estimated.
从20世纪50年代起，苏联就开展了关于放射性核素向动物体内转移的广泛研究。这些研究中很少有发表在国际同行评议文献中，或被纳入国际综述。本文延续了一系列对俄语放射性核素向动物体内转移文献的综述，提供了放射性核素在各种动物组织中的生物半衰期信息。在可能的情况下，将这些数据与其他国家报告的数据进行比较。数据通常使用单指数或双指数进行量化，以考虑不同比例的损失。对于一些产品，如牛奶，大多数放射性核素的生物半衰期往往较快，为1 - 3天，并且在很大程度上由单指数描述。然而，对于其他动物产品，生物半衰期可能因动物的年龄和大小等许多因素而有很大差异。实验方案，如研究持续时间、放射性核素给药和/或样本采集方案，也会影响估计的生物半衰期值。
