Dosimetric impact of indoor radon gas on the population from the commune of Yopougon, Abidjan, Côte d’Ivoire
Radon gas is the main natural source of exposure of the population to ionizing rays. Because of its impact on the health, this radioactive gas has become a great concern worldwide. In this study, radon concentrations in the air of some dwellings in Yopougon, one of the commune with the highest popul...

The corresponding annual effective doses obtained vary from 0.66 to 4.37 mSv.y−1. The mean value calculated which is 2.35 mSv.y−1 is higher than the action level (1 mSv.y−1) prescribed by ICRP 103, and also to the limits recommended by the WHO and the International Research on Cancer Center (IRCC).
