在较强辐射环境下用γ谱分析方法进行核素分析时,若周围环境中的核素与被测样品的核素相同,则将对样品分析产生很大干扰。确定和消除环境中干扰核素的影响是样品定量分析中的重要问题。当被测核素置于容器中时,由于容器对样品γ射线的屏蔽作用,这一问题显得更突出。本实验对上 When the radionuclide analysis is carried out by γ-ray analysis in a strong radiation environment, if the nuclide in the surrounding environment is the same as the nuclide of the sample to be measured, the sample analysis will be greatly disturbed. Determining and eliminating the effects of interfering nuclides in the environment is an important issue in the quantitative analysis of samples. When the test nuclide is placed in a container, the problem is more pronounced due to the shielding effect of the container on the gamma rays of the sample. This experiment is right
