Environmental radiological assessment is an essential process for characterizing human exposure levels in order to limit or reduce the risks associated with exposure to ionizing radiation. The approach involves identifying the transfer pathways of radionuclides and assessing the potential risks to ecosystems and nearby populations. To optimize the use of resources and adapt the level of analysis to the degree of radiological risk, international radiation protection organizations recommend the application of the graded approach in radiological impact studies. This approach consists of adjusting the depth and complexity of the assessment according to the potential significance of the radiological impacts associated with a given activity. Indeed, after energy and efficiency calibration, the peaks identified and correct for background radiation show that the calculated mass activities obtained after peak integration do not indicate any abnormal levels. Thus, the results of this study will contribute to establishing a database for environmental radiological monitoring.
Author Keywords: environment, artisanal activity, mass activity, risk index, radium equivalent.

Abstract: (french)
L’évaluation radiologique environnementale constitue un processus essentiel pour caractériser les niveaux d’exposition de l’homme afin de limiter ou réduire les dangers liés à l’exposition aux rayonnements ionisants. Cette démarche implique d’identifier les voies de transfert des radionucléides et évaluer les risques potentiels pour les écosystèmes et les populations riveraines. Afin d’optimiser l’utilisation des ressources et d’adapter le niveau d’analyse au degré de risque radiologique, les organismes internationaux de radioprotection recommandent l’application de l’approche graduée dans les études d’impact radiologique. Cette approche consiste à ajuster la profondeur et la complexité de l’évaluation en fonction de l’importance potentielle des impacts radiologiques associés à une activité quelconque. En effet, après un étalonnage en énergie et en efficacité, les pics trouvés soustrait du bruit de fond, les activités massiques calculées après intégration des pics ne démontrent pas un niveau anormal. Ainsi, les résultats de cette étude permettront de constituer une base des données pour la surveillance radiologique environnementale.
