摘要: Assays of alpha- and beta-emitting radionuclides in swipe samples are often required to monitor the presence removable surface contamination for radiological protection control nuclear facilities. Swipe analysis has also proven be a very sensitive analytical technique detect signatures safeguard verification purposes. A new sequential method determination actinide isotopes radiostrontium samples, which utilizes streamlined column separation with stacked anion extraction chromatography resins, been developed. To validate procedure, spike blank were prepared analyzed by inductively coupled mass spectrometry (ICP-MS), alpha liquid scintillation (LS) counting. Low detection limits have achieved isotopic Pu (238Pu, 239Pu, 240Pu, 241Pu), U (234U, 235U, 238U), Am (241Am), Cm (242Cm, 243/244Cm) Sr (90Sr) at ultra-trace concentration levels samples.
