Table 1-1 Measured 90Sr concentration in 0.1 g of cattle bone and tooth using the proposed ICP-MS and radiometric methods
Comparable radioactivity concentrations of 90Sr in 0.1 g of hard tissues were found using the proposed and conventional radiometric methods. Further, the proposed method using ICP-MS had a lower detection limit than did the radiometric method.
