为了测量101Tc的核数据,需要得到放化纯的101Tc样品。但101Tc的半衰期(T1/2=14.02min)很短,传统的手动分离方法难以达到快速分离的目的。为此,需要研制101Tc快速分离装置。本工作建立了101Tc的手动分离方法。该方法采用100Mo中子俘获反应生成101Mo,101Moβ-衰变产生101Tc。采用40%α-安息香肟-乙酸乙酯萃取干扰核素Mo,两次萃取后可得放化纯101Tc样品。依据上述分离方法,研制了1套101Tc快速分离装置。该装置由机械部分和远程控制系统组成。
In order to measure 101Tc nuclear data, it is necessary to obtain a radiochemically pure 101Tc sample. However, the half-life of 101Tc (T1 / 2 = 14.02min) is very short, and the traditional manual separation method is difficult to achieve rapid separation. To this end, the need to develop 101Tc rapid separation device. This work established a 101Tc manual separation method. The method uses 100Mo neutron capture reaction to generate 101Mo, 101Moβ-decay to produce 101Tc. Interfering interference nuclide Mo was extracted with 40% α-benzoin-oxime-ethyl acetate, and two pure samples of 101Tc were obtained after twice extraction. According to the above separation method, a set of 101Tc rapid separation device was developed. The device consists of a mechanical part and a remote control system.
