Abstract
The objective of this work is to carry out indoor radon measurements in the uranium regions of Poli and Lolodorf in which lie the uranium deposits of Kitongo and Lolodorf, prior to their impending exploitation. The indoor radon concentration was measured in 103 and 50 dwellings located respectively in Poli and Lolodorf using E-PERM electret chamber detectors. Indoor radon distributions in Poli and Lolodorf follow the lognormal law. Radon concentrations range respectively in Poli and Lolodorf between 29 and 2240 Bq mâ3 and 24-4390 Bq mâ3 with corresponding median values of 165 Bq mâ3 and 331 Bq mâ3. Corresponding arithmetic and geometric means are respectively 294 Bq mâ3 and 200 Bq mâ3 for the uranium region of Poli, 687 Bq mâ3 and 318 Bq mâ3 for the uranium region of Lolodorf. For the uranium region of Poli, 80% of dwellings have radon concentration above the reference level of 100 Bq mâ3 and 20% of dwellings show a radon concentration above 300 Bq mâ3. For the uranium region of Lolodorf, 80% of dwellings have radon concentration above 100 Bq mâ3 and 50% of dwellings show a radon concentration above 300 Bq mâ3. Thus radon monitoring and mitigation plan are required to better protect people against harmful effects of radon.
