Non-destructive Neutron Activation Analysis of Aluminium and Phosphorus in Bone Biopsies

Summary: The level of aluminium and phosphorus in bone was measured by neutron activation analysis via the short lived radionuclide 28A1. The contribution of both elements to the 28A1 activity could in each case by determined after the samples had been irradiated twice, once with a cadmium shield around the irradiation position. The samples were analysed non-destructively and may later be used for further tests. Limits for the quantitative determination of aluminium and phosphorus in usual bone biopsies were calculated
