The purpose of this research was to measure the concentration of radon gas in the school in the city of Kaya and to evaluate the effective dose in the lungs and the risk of cancer. This study used Corentium's AIR THINGS digital radon detector to determine the radon concentration in sixteen (16) schools. The digital radon detector air Things of Corentium was placed in each office for a minimum period of one week and the concentration values were recorded every 24 hours. The values recorded in each school were the short-term average and the long-term average during seven days of measurement. The highest short-term average concentration was 82.11 Bq/m3, and was calculated in School 10 (Lycée Provincial Moussa Kargougou). The maximum radon concentration value measured in the short term in school 10 was 298 Bq/m3. The maximum long-term radon concentration value measured in the school 10 was 63.00 Bq/m3 and below the limit of 100 Bq/m3 recommended by the WHO. The average concentration of radon gas in schools in the city of Kaya was 11.19 ± 5.97 Bq/m3. This concentration was well below the limit recommended by the WHO. http://pubs.sciepub.com/pmc/9/1/2/pmc-9-1-2.pdf radon concentration school absorbed dose effective dose
