Methodology to determine the efficiency of a beta emitter gases monitor

Creators

Description

This work presents a methodology developed to determinate the efficiency of air monitors used to measure the concentration of beta emitters noble gases in nuclear power stations. Efficiency values, obtained by means of theoretical computation are compared with experimental values. The experimental part of the work was performed using three different point beta source, to simulate small amounts of gas uniformly distributed in small volume. The comparison shows that theoretical an experimental values agree within 4,2 % for 90Sr + 90Y, 204Tl and 45Ca beta sources. (author)
