Publication number: 20230375725Abstract: Disclosed is a method for determining 224Ra in a sediment by using a pulse ionization chamber emanometer, which belongs to the technical field of analysis and measurement. A pulse ionization chamber emanometer (PIC), a new emanometer, is used. Based on the half-life characteristics of different radon isotopes, one can separate the 220Rn activity from the total counts by dual counting. The resulting 220Rn measurement then can be used to determine the 224Ra activity in sediment according to the principle of secular radioactive equilibrium.Type: ApplicationFiled: July 20, 2022Publication date: November 23, 2023Inventors: Guangquan Chen, Wen Liu, Shibin Zhao, Chunqian Li, Jinjia Guo, Yancheng Wang, Bochao Xu, Xiaofei Yin, Shan Sun
