It has been found that a delayed variation process of long duration of the hafnium numbers after irradiation occurs when the dose is greater than 5×106 rads. This variation process can be stopped by lowering the temperature to that of liquid nitrogen and it does not appear when the dose is lower than 4.59×105 rads. The general rule is that the values of the hafnium numbers drop rapidly a...             本文借助铪指数实验研究了30％TBP-煤油-硝酸体系的辐照后效应。发现在上述体系中,当辐照剂量大于5×10~6拉德时,铪指数有一个持续很久的变化过程。这一变化过程能借助液氮的低温使其停止变化。当辐照剂量低于4.59×10~5拉德时就没有这个变化过程。实验证明,除了铪指数的“起始值”外,还存在一个“平衡值”,两者有很大的差别,因此,文献上所提出的0.5N的水相硝酸浓度对生成永久性有害降解产物是最有利的浓度这一结论是不全面的。实验结果表明,有害降解产物是一个含有活泼氢的次级辐解产物。 文摘来源          The extraction of Neptunium (Ⅳ) by ten crown ethers with various substituting groups from nitric acid solution have been investigated.
