子体核素 meaning in English

daughter nuclide
daugther nuclide

Since the half - lives of neptunium - 237 and its daughter radionuclides are relatively short comparing to the age of the earth , these radionuclides are not present in the earth nowadays
由于- 237及其子体核素的半衰期远低于地球的年，它们现已不存在于地球上。相反，
The encoding of the data by ann approach is a promising method for the measurement of uranium samples . the determination of the shielded uranium , in particular , by passive gamma - ray detection is a formidable challenge . gamma rays are ideal probes for determining the attributes of uranium in nuclear material transparency monitoring and verification of safeguards regime
2 % ;封装浓缩铀属性的判定一直是nda测量技术中的难点问题，本工作提出了一种辅助探测的方法并给出了高浓铀的判定依据，该方法通过探测232u衰变子体核素208t1的2614 , 75kev特征射线能峰确定铀样品中是否存在232u ,从而判定封装样品是否为高浓铀。
