Automated neutron-activation analysis of biological material with high radiation levels

Abstract

A method has been developed for the chemical separation and subsequent γ-spectrometric analysis of the alkali metals, the alkaline earths, the rare earths, chromium, hafnium, lanthanum, manganese, phosphorus, scandium and silver in neutron-activated biological material.

The separation steps, which are fully automatic, are based on a combination of ion exchange and partition chromatography and require 40 minutes for their completion.
