Abstract  

This paper presents the results of the application of a fast rabbit system and a high thermal neutron flux to neutron activation analysis of selenium in environmental samples. The short-lived radionuclide77mSe, (17.5s) is used for analysis. Results are presented for selenium in sea-water and rain-water, in biological reference materials, in food-stuffs and milk powder, in human hair and human blood-serum.

Abstract  

A correction procedure is presented for the residual bias due to dead time losses in thermal INAA based on short-lived radionuclides. It is based on a linear least-squares fitting, starting from three pre-chosen (average) half-lives.
