摘要
采用TRPO萃取—单酰胺(NA)反萃—电沉积制源,以α谱仪测定^(237)Np、^(239+240)Pu、^(241)Am、^(244)Cm等常见核素的活度。该方法在事故应急监测以及液态流出物监测中,对低放废液中上述主要α核素的定性识别和定量分析有较好的应用。
A TRPO （trialkyl phosphine oxides） extraction -NA （single amide） reverse extraction- electrodeposition method was utilized for the preparation of alpha counting sources to determine the activities of some common radionuclides （e. g. ,^237 Np, ^239 ＋240pu, ^241 Am and ^244Cm ） by alpha spectrometry. The results showed that this method could be effectively applied for the qualitative identification and quantitative measurement of the key alpha emitting radionuclides in emergency monitoring and liquid effluent monitoring.
