Measurement of 90Sr in bone ash.
Bone is a critical organ for the accumulation of many radionuclides, including 90Sr. A bone ash has been prepared by NIST to become a standard reference material and the assaying of the 90Sr activity concentration is reported. A radiochemical procedure, based on extraction chromatography using a crown ether, has been developed to separate Sr from the bone ash. The natural Sr content of the bone ash has been determined by isotope dilution inductively coupled plasma mass spectrometry. The 90Sr activity concentration has been measured by low-level liquid scintillation counting.
