title: Non-destructive neutron activation analysis of aluminium and phosphorus in bone biopsies.
abstract: The level of aluminium and phosphorus in bone was measured by neutron activation analysis via the short lived radionuclide 28Al. The contribution of both elements to the 28Al activity could in each case by determined after the samples had been irradiated twice, once with a cadmium shield around the irradiaion 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.
