一、概述自射线照相技术在十九世纪出现,第二次世界大战后得到较大的发展。1964年已有用自射线照相技术来研究核燃料的报道。燃料的α自射线照相主要用途是在Pu基燃料中把Pu区分出来,或者研究PuO_2与UO_2燃料分布的均匀性等,与宏观照相对比,能发现一些新的情况。自射线照相在燃料中能把Pu区分出来是由于Pu的比放射性高,从表1中可看出,

First, an overview Self-radiography appeared in the nineteenth century, after the Second World War to get greater development. In 1964 there have been reports of using nuclear radiography to study nuclear fuel. The main use of alpha autofluorescence of fuels is to distinguish Pu from Pu-based fuels, or to study the uniformity of PuO_2 and UO_2 fuels. Compared with macro photography, some new situations can be found out. Since radiography can distinguish pu from fuels due to the higher specific radioactivity of Pu, as can be seen from Table 1,
