The uranium content of several human tooth, bone and soft tissue samples was determined by the fission tract method. The average uranium content in teeth, bones and soft tissues were 6.7, 8.4 and 64 ppb ash, respectively. The distribution of uranium in bones is less uniform than that of teeth, and the uranium content of soft tissues is generally higher than that of teeth and bone. The presence of thorium does not interfere with the uranium determination in most cases.
采用裂变径迹法测定了几个人类牙齿、骨骼和软组织样本中的铀含量。牙齿、骨骼和软组织中的平均铀含量分别为6.7、8.4和64 ppb（灰分）。铀在骨骼中的分布不如在牙齿中均匀，软组织中的铀含量通常高于牙齿和骨骼。在大多数情况下，钍的存在不会干扰铀的测定。
