Correction for radon distribution in solid/liquid and air phases in gamma-ray spectrometry

Appl Radiat Isot. 2012 Sep;70(9):2119-23. doi: 10.1016/j.apradiso.2012.02.080. Epub 2012 Mar 2.

Abstract

The effect of radon diffusion and distribution between a (226)Ra matrix and the top air gap inside sample containers for gamma-ray spectrometry was studied. Containers filled at almost 100% or just 70% of total capacity yielded correction factors of about 7% and 20% respectively. Applying these correction factors allowed activity values calculated from (226)Ra or radon decay products to agree within 2%.
