THE DETERMINATION OF SELENIUM IN BIOLOGICAL MATERIAL BY RADIOACTIVATION
Neutron-activation analysis was applied to the determination of selenium in biological material. Samples were activated in a flux of 10/sup 12/ neutrons per cm/sup 2/ per second for 18 minutes, and a rapid chemical separation was developed for Se/sup 81/. Under these conditions the practical limit of sensitivity was found to be 5 x 10/sup -9/ g. Decontamination from arsenic, bromine, manganese, sodium, and zinc was tested and found to be satisfactory. Selenium contents of fertilizers, tomato tissue, and human blood were measured by the procedure. (auth)
