【摘要】 采用4πβ-γ符合吸收法测量燃耗监测体¹⁴⁴Ce的活度,此种方法准确度较高,且不需要知道衰变纲图的核参数,但是对于大量测量来说,显得太烦琐费时,同时,为提供一种可作比较的方法,对参数法也做了一些工作,并与符合吸收法进行比较,二者在1%左右符合。更多还原

【Abstract】 In this paper a brief description is presented on the measurement of radioactivity of cerium-144 by a 4np-Y coincidence parameter method. The result of measurement compared with that of measurement of radioactivity of cerium -144 by 4np-Y coincidence absorber method, The two results agree quiet well.更多还原
