Radon emanation in Saskatchewan soils.

Saskatchewan prairie soils in central Canada were studied from areas where many homes are known to exceed the Health Canada indoor radon guideline of 200 Bq m. This study sampled 32 soils from 11 sites, which varied in clay content and presence of bedrock materials. Soils were analyzed for (238)U, (226)Ra, (222)Rn in soil gas, bulk density, moisture, and particle size.
