在這例子中,
* 釷-234,鏷-234m,…,鉛-206是鈾-238的衰變產物;
* 釷-234是鈾-238的
* 鏷-234m (234 metastable)是鈾-238的[至孫同位素][?]。

在原子核物理学中,衰变产物(也称子核种、子同位素)是指一个放射性核种经过辐射衰变后形成的新核种。辐射衰变通常涉及一连串的衰变过程(称衰变链)。例如,铀-238(U-238)衰变成钍-234(Th-234),钍-234(Th-234)再衰变成镤234(Pa-234),而镤-234(Pa-234)再衰变成…,最终衰变成稳定的铅-206(Pb-206):
在这例子中,
- 钍-234,镤-234m,…,铅-206是铀-238的衰变产物;
- 钍-234是铀-238的子同位素;
- 镤-234m (234 metastable)是铀-238的[至孙同位素][?]。
These might also be referred to as the daughter products of U-238.[1]
