Dynamics of radon and its decay products inside an accumulative chamber

Research output: Contribution to journalArticle

Abstract

The calculations of radon and its decay products accumulation dynamics inside a chamber designed for measurements of radon flux density from the soil surface were carried out in the present work. Dynamics of alpha-, beta-particles and gamma-ray yields under decay of accumulated radionuclide nuclei was calculated based on the accumulated activity. Ion production rate inside the accumulative chamber due to ionizing radiation of different types was estimated. Thoron and its decay products accumulation regularities inside the accumulative chamber were also estimated and potential effect of thoron on measurement results (if counting regime is used) was analyzed in detail. Dynamic equations of the studied radiation characteristics, their solutions and obtained results analysis are presented.
