本方法是由环境水中铯-137的分析方法移植过来的,因此只做了尿样前处理、树脂对铯-137的吸附、酸度对吸附铯-137的影响、高低示踪全程回收率、100毫升人尿和试剂本底的实验。该方法包括尿样酸化处理,用金属盐阴离子交换树脂-亚铁氰化钴钾吸附,4-仲丁基-2(α甲苄基)酚(BAMBP)萃取,再用硝酸反萃,制源,用低本底β计 This method is transplanted from the analysis of cesium-137 in environmental water, so only the urine sample pretreatment, the resin adsorption of cesium-137, the effect of acidity on the adsorption of cesium-137, the full traceability of the tracer, 100 Human urine and reagent background experiments. The method comprises the acidification of urine sample, extraction with potassium metal cations of potassium ferrocyanide, extraction with 4-sec-butyl-2 (alpha methylbenzyl) phenol (BAMBP) and subsequent stripping with nitric acid, , With low background β meter
