ANALYTICAL METHOD FOR THE DETERMINATION OF BETA-ACTIVITY (TRANSMITTED THROUGH A TOTAL ABSORBER THICKNESS 5mg Al/sq.cm) IN PLUTONIUM PLANT SOLUTIONS AND EFFLUENTS

Technical Report ·
OSTI ID:4238488
A measured portion of the sample is evaporated to dryness on a stainless- steel counting tray. The BETA activity of the residue is measured using standard G.M. eqiupment with a thin-end-window counting tube. The equipment is calibrated against standard strontium90/yttrium-90 sources in equilibrium, prepared from solutions of known strontium-90 content and the observed activity is expressed as d.p.m. Sr/sup 90//Y/sup 90/.
