【摘要】 本文报告了一个刻度源及测量对象都是采用传递样品方式进行的实验室间γ分析比对。文中特别对外源性X射线干扰的影响进行了研究和较详细的叙述。此外,本工作还对影响比对结果的其它因素也做了讨论,它明确指出,那些受外源性特征X射线干扰的特征γ峰不应该被用来测定样品的γ放射性活度。最后,本文还对以往的一些环境辐射调查阐述了一些联想。更多还原

【Abstract】 A comparison on determining activities of 238U and 232Th based on transfer samples is reported in the paper.Especially,disturbance of X-ray from out-sources i.e.non-nucleus-self are studied and more detailed.And other factors that influence this time comparison result are discussed too in the work.In the paper it is pointed out definitely that the characteristic peaks that are disturbed by characteristic X-rays from out-sources ought to be not adopted to determine activities of the samples.In final some associations of ideas for some investigation passed of environment radiation are also described.更多还原
