Measurement of 236U in human tissue samples using solid phase extraction coupled to ICP-MS

Author affiliations

Abstract

236U is present at ultra-trace levels in typical environmental and biological samples. Typically, it has been measured by highly sensitive techniques, such as accelerator mass spectrometry. This paper reports the measurement of 236U in 20 human tissue samples using a sector field ICP-MS following automated SPE separation. The tissue samples were selected from one USTUR case, representing tissues/organs that are important for internal radiation assessment. Another uranium isotope, 235U, was also measured in the samples. The results for 235U were compared with those obtained by alpha spectrometry. For most cases, results from the two methods were comparable, indicating that the measurement of 236U in the samples is reliable.
