Abstract
Bone is a critical organ for the accumulation of many radionuclides, i ncluding Sr-90. A bone ash has been prepared by NIST to become a stand ard reference material and the assaying of the Sr-90 activity concentr ation is reported. A radiochemical procedure, based on extraction chro matography using a crown ether, has been developed to separate Sr from the bone ash. The natural Sr content of the bone ash has been determi ned by isotope dilution inductively coupled plasma mass spectrometry. The Sr-90 activity concentration has been measured by low-level liquid scintillation counting. (C) 1998 Elsevier Science Ltd. All rights res erved.
