针对后处理1AP有机相样品分析,研究建立了一套1AP中U、Pu及总γ分析装置。采用低功率冷阴极管激发U、Pu的L系X射线荧光,电致冷Si-PIN探测器探测。采用NaI探测器测量1AP中总γ放射性强度。对装置进行了密封式设计,将X光管、探测器与样品通过特殊的窗口隔离, For the post-processing 1AP organic phase sample analysis, a set of 1AP U, Pu and total γ analysis device was established. Low-power cold-cathode tubes were used to excite U and Pu L-type X-ray fluorescence and electrosurgical Si-PIN detector. The total radioactivity in 1AP was measured using a NaI detector. The device was sealed design, the X-ray tube, the detector and the sample through a special window isolation,
