| 摘 要： | 本文报道了对ＩＡＥＡ１１５号安全丛书列出的具有长期放射平衡子体的３３种母体核素各向同性点源总剂量学常数值的计算结果，其中含空气比释放动能率常数、照射量率常数、周围剂量当量率常数和定向剂量当量率常数；提出了未经化学分离的天然铀定义，并计算了相应的剂量学常数值；此外，还对某些核素的衰变链作了适当讨论。

| Abstract: | The paper presents the calculated results of total values of dosimetric constants for isotropic point sources of 33 parent nuclides and their progeny included in secular equilibrium which were listed in IAEA safety series No.115, including air kerma rate constant,exposure rate constant,etc.ambient dose equivalent rate constant and dirctional dose equivalent rate constant.The definiton of natural uranium which is not separated chemically is given, and corresponding dosimetric constants are calculated. Decay chians of some parent nuclides are discussed as well. ( |
