Physical Processes Affecting Levels of Radon, Thoron, and Their Decay Products in an Indoor Environment. Final Technical Report

摘要

The objective was to understand the physical processes affecting radon, thoron, and their daughter products in the indoor environment. Specific areas of research were: (1) the importance of thoron and thoron daughters as contributors to indoor radiation dose; (2) transport modeling for radon and thoron; (3) radon and thoron daughter ion-aerosol interactions; (4) indoor-outdoor radon levels and their relation to air exchange processes; and (5) publication and synthesis of research from earlier investigations.
