Abstract
Using the technique of liquid scintillation,32P and45Ca activites were determined in biological samples such as bones, blood, milk and egg shells, white and yolk. Samples were mineralized in 70% HClO4 and 30% H2O2 at 70 °C and measured after addition of the “Aquasol” scintillation liquid. A correction for quenching was made by the method of sample channels ratio. High detection efficiencies were obtained, above 80% for45Ca and about 50% for32P in a second measuring channel. Recoveries amounted to 0.95–1.06 for32P and to 0.93–0.98 for45Ca.
