Abstract
Concentration levels and effective exposure dose of radon were determined in mines, industries and dwellings in the
Districts of Tororo and Busia, Eastern Uganda in 60 indoor structures between November 2010 and April 2011,
using activated charcoal canisters and sodium iodide detector. This study was undertaken to assess the radiological
risk of radon exposure in selected areas in Eastern Uganda. The radon concentration levels were found to vary from
28±1 to 97±5 Bqm-3 and the effective dose varied from 0.71±0.03 to 2.44±0.13 mSvy-1, respectively. Over all the
mean radon concentration values reported were all below the United Nations Scientific Committee on the Effects of
Atomic Radiation (UNSCEAR) and International Commission on Radiological Protection (ICRP) recommended
radon action level of 200 Bqm-3. Some average radon concentration values were close 100 Bqm-3 an action level
recommended by World Health Organization (WHO). This means radon levels are still within limits, however
necessary mitigation measures need to be taken so that radon levels are not elevated beyond the mean values
reported in this work.
