Determination of selenium in glass by a radioactivation method

JSGT 1958 V42 T084-T087

To determine the total quantity of selenium left in a glass after addition of a decolourizer, samples of the glass with and without the selenium additive were irradiated together in a nuclear reactor. By comparing the resulting y-radiations with a differential type of scintillation spectrometer, selenium contents of 10 parts per million were readily determined. This use of inactive tracers revealed by radioactivation analysis is of wide potential application in production processes where radioactivity in the product has to be avoided.
