Abstract
In the indoor,with the help of Falcon portable HPGe gamma spectrometer provided by CANBER-RA,by using the relative measurement method,we make a radionuclide analysis on the core (mainly238U).The ex-perimental material is the standard material for the national level two uranium ore.In the experiment,five samples of238U were measured,and the content of238U in the samples was measured by the "Donghua Institute of engineer-ing and engineering analysis and testing research center".There are some errors in the results and chemical analy-sis of the238U results obtained from the analysis of five samples with known contents.The experimental results show that in measurement of the content in core of238U samples,compared with the chemical method,gamma ray spectrometry method can be more accurate.关键词
