Uranium backup pro tape serial2/15/2023 ![]() Over the years, several analytical separation methods and techniques have been employed for these types of analyses. The bioassay of urine and fecal samples has been used since the 1940s to determine an individual's uptake of uranium and actinide elements such as americium and plutonium. KeywordsUranium–Urine–Alpha spectrometry–Isotopic analysis–Bioassay With 48h of counting, the minimum detectable activity concentrations were determined to be 0.43, 0.21 and 0.42mBq/L The 232U tracer was utilized for chemical recovery correction, and an average recovery of 76.2☘.1% was found for 1400mL urine Replicate spike and procedural blank samples were prepared and measured to validate the procedure. Alpha spectrometry is used for isotopic uranium analysis after preparation of a thin-layer counting source by ceriumįluoride micro-precipitation. Uranium is co-precipitated with hydrous titanium oxide (HTiO) from urine matrix, and is then purified by anion exchange chromatographicĬolumn. New radiochemical separation procedure has been developed to provide isotopic uranium analysis in urine samples. Urine assay is the preferred method for monitoring accidental or chronic internal intake of uranium into the human body. ![]()
