ABSTRACT
In the present study, the activity concentrations of radon were measured in twenty-seven (27) water samples collected from Villy, a village of west central region which presents uranium anomalies. The associated radiological hazards were then assessed. The radon activity concentrations were in the range of 5.77±0.74 to 441.76±4.45 Bq.L-1 with an average of 157.31±2.30 Bq.L-1. The lower detection limit of the instrument SARAD EQF 3200 is 0.106 Bq.L-1. The average total annual effective dose due to radon was 1.06 mSv.y-1 with the range of 39 µSv.y-1 to 2.99 mSv.y-1. 70.37 % of the measured radon concentrations are found to be higher than 100 Bq.L-1, the reference levels of World Health Organization and European Union but were lower than the European Union action level of 1000 Bq.L-1. Accordingly, it does not pose any significant health hazards to the populace of Villy.
Keywords : Radon, SARAD EQF 3200, Activity concentration, Reference level.
RESUME
Dans la présente étude, les concentrations d’activité du radon ont été mesurées dans vingt-sept (27) échantillons d’eau prélevés à Villy, un village de la région du centre-ouest qui présente des anomalies d’uranium. Les dangers radiologiques associés ont ensuite été évalués. Les concentrations d’activité du radon se situaient entre 5,77±0,74 et 441,76±4,45 Bq.L-1, avec une moyenne de 157,31±2,30 Bq.L-1. La limite inférieure de détection de l’instrument SARAD EQF 3200 est de 0,106 Bq.L-1. La dose efficace annuelle totale moyenne due au radon était de 1,06 mSv.an-1, avec une plage de 39 μSv.an-1 à 2,99 mSv.an-1. 70,37 % des concentrations de radon mesurées sont supérieures à 100 Bq.L-1, niveaux de référence de l’Organisation Mondiale de la Santé et de l’Union Européenne, mais inférieures au seuil d’intervention de l’Union Européenne de 1000 Bq.L-1. En conséquence, il ne pose pas de risques significatifs pour la santé de la population de Villy.
