ABSTRACT: This work presents a preliminary study on groundwater samples carried out from selected groundwaters of some localities of Yaounde, Cameroon. Radon concentration was ranged from 0.11 Bq∙l-1 to 1 Bq∙l-1, with an average of 0.48 Bq∙l-1. The comparison between the physico-chemical parameters and the radon concentrations in groundwater showed a good correlation between these radon concentrations and the values of Electroconductivity (EC). The annual effective dose due to ingestion of radon in water ranged from 0.30 μSv∙y-1 to 7.90 μSv∙y-1 with an average of 1.93 μSv∙y-1. The obtained results of this study were shown that the concentrations of radon in groundwaters and annual effective doses due to ingestion of this groundwater were below the references recommended by WHO.
