Abstract
Instrumental procedures for phosphorus and calcium analysis in bone by activation with 14 MeV generated by a Van de Graaff accelerator are p resented. The variation of the neutron flux was followed by a BF3 dete ctor. Mathematical equations used for the normalization of neutron flu x during the irradiation are reported. Calcium analysis was performed by cyclic irradiation. Results obtained for the IAEA reference materia l A3/74 were (15.6 +/- 1.8)% for phosphorus and (31.8 +/- 4.1)% for ca lcium.
