Three facilities (CIEMAT, HMGU and HML) have used their in vivo counters to compare two leg phantoms. One was commercially produced with (241)Am activity artificially added to the bone inserts. The other, the United States Transuranium and Uranium Registries' (USTUR) leg phantom, was manufactured from (241)Am-contaminated bones resulting from an intake. The comparison of the two types of leg phantoms showed that the two phantoms are not similar in their activity distributions. An error in a bone activity estimate could be quite large if the commercial leg phantom is used to estimate what is contained in the USTUR leg phantom and, consequently, a real person. As the latter phantom was created as a result of a real contamination, it is deemed to be the more representative of what would actually happen if a person were internally contaminated with (241)Am.
三个设施（CIEMAT、HMGU 和 HML）使用他们的体内计数器比较了两个腿部模型。一个是商业生产的，其骨插入物中人工添加了（241）Am 活性。另一个是美国超铀元素和铀登记处（USTUR）的腿部模型，由摄入导致的受（241）Am 污染的骨头制成。两种腿部模型的比较表明，这两种模型在活性分布上并不相似。如果使用商业腿部模型来估计 USTUR 腿部模型和相应的实际人包含的骨活度，那么骨活度估计可能会出现很大的误差。由于后一种模型是由于真实污染而创建的，因此它被认为更能代表如果一个人内部受到（241）Am 污染会实际发生的情况。
