Abstract
Background The World Health Organization (2016) confirms that humans who are exposed to Radon-222 can significantly suffer from risks of lung cancer. Measuring radon concentrations indoors environment, including houses and workplaces, has become a high priority nowadays.
Aim: To assess the radon exposure risk for students and staff in such locations.
Methods: In this research, radon concentrations were measured inside 14 sites at the Girls' Campus - Jouf University - Sakaka City- KSA by using a RAD7 radon detector for the purpose of estimating the possibility of any risks related to exposure to radon inside these sites.
Results: It has been found that the concentration levels of Radon varied from 13.5 +/- 1.8 to 29.2 +/- 2.6 Bq/ m(3) representing an average of 19.5 +/- 2.5 Bq/m(3). The observed total of effective dose per year caused by radon inhalation was found to range from 0.142 to 0.307 mSv/y, with a mean of 0.21 mSv/y.
Conclusion: The study concluded that the concentration levels of radon and the effective doses per year were lower than the recommended limits. Further, the obtained values of the estimated Excess Life Time Cancer Risk (ELCR) revealed low potential hazards resulting from exposure to radon in the studied sites.
