Final Report: Radon: Gas Transport in Soils and its Relation Toradon Availability: Hot Spot Identification and Flow Characteristics Near Structures, May 1, 1996 - September 30, 1997

摘要

There were 3 major objectives being addressed in this research. The first was to coordinate ground-truth quality assurance in the DOE/LBL/EPA cooperative study to determine a methodology to predict the areas where indoor radon concentrations have the highest probability of exceeding 20 pCi/L (750 Bq/md). the second was to examine 2 common types of homes (basement and non-basement) for yearly radon variation by monitoring specific parameters under normal living conditions. The third task was to develop a rapid field method to determine the thoron (Rn-220) content of soils that would complement the rapid method of Rn-222 content that was earlier developed under this proposal.
