Description
Summary:Determination technique of radon exhalation rate (RER) from soils in field measured by track detector CR-39 was developed. For this purpose, the method “Russian dolls” (matrieshka) was created and used, consisting of three cylindrical plastic chambers and located inside each other. Entrance mouths of chambers are installed in opposite directions to make an artificial barrier up on the path of 220 Rn. Field measurements of the RER from soils were within 16.4–22.1 Bq/m 2 h, that are 160 and 220 times more than laboratory measurement. The RER values from soils as laboratory and field measurements have been compared with the data of other authors.
