At low HNO3 concentration and dilution factor above 2, 0.1 mol/L DCH18C6/1-octanol extracts very little americium,plutonium and uranium.The distribution ratios of Am、Pu and U increase with the increase of HNO3 concentration in aqueous phase,and decrease with increasing of dilution factor of HLLW.The distribution ratio of extraction of Pu increases with the increase of extractant concentration.
研究结果表明,在低硝酸浓度和较大稀释倍数情况下,DCH18C6对镅、钚、铀的萃取分配比都比较小,并随着水相硝酸浓度的增大而增大,随着模拟高放废液稀释倍数的增大而减小,提高萃取剂浓度会增大四价钚的萃取。

It is important that studying gamma ray spectrometry of field rocks and soil in the earth抯 crust. Their energy range are mainly 30-3000keV, they contain abundant information of natural radioactive nuclides, such as uranium, thorium, potassium, etc, and of artificial radioactive nuclides from nuclear engineering activity, such as cesium, americium, cobalt, etc, and of the results in interaction between gamma ray and earth抯 crust.
国外近年已经生产出大于256道的伽玛射线能谱仪,但由于仪器应用滞后于仪器研究,且仪器稳谱未完全解决,获取全谱信息困难,加之对低能谱段的认识不足等原因,致使野外应用仍然滞留在仅限于测定铀钍钾含量的伽玛能谱测量水平上。
