Abstract
The determination of phosphorus in milk and bone samples by both radio chemical and instrumental neutron activation analysis is described. Th e radiochemical method consists of thermal neutron irradiation of samp les and standards, sample dissolution, phosphorus precipitation as amm onium phosphomolybdate, use of zinc holdback carrier and counting of t he phosphorus-32 beta-activity. The instrumental method involves therm al neutron irradiation of samples and standards, waiting for a decay t ime and beta-counting. The methods were applied to commercial samples and reference materials.
