Assessment of Radiological Hazards in Drinking Water (Mineral Water) Consumed by the Malian Population Using Gamma Spectrometry

Background: Qualitatively risk to human health is the product of the probability that contaminated water or food will be ingested and the radiological consequence or damage due to the intake. The human being activities can increase the deposition and transportation of naturally occurring radioactive materials (NORM) in the groundwater and surface water bodies. The determination of radionuclide concentration in twelve (12) drinking water in Mali, the calculation of annual effective dose due to their ingestion, the calculation of risk assessment, etc. will permit to the AMARAP to avoid any over exposition (determinist effects) and minimize as well the associated risk due to low doses (stochastic effects). Materials and Methods: The health impact due to ingestion of radionuclides from these drinking waters was evaluated by the determination of activity concentration of radionuclides U-238, Th-232 and K-40 using gamma spectrometry analysis. The concentration of gross alpha/beta counting was also evaluated and the radiological hazards were calculated in in these drinking waters. Results: The range of activity concentrations for U-238 vary from 0.24 ±0.02 to 9.42 ± 0.8 Bq/l, for Th-232 from 0.28 ± 0.02 to 5.54 ± 0.28 Bq/l and for K-40 from 0.44 ± 0.03 to 4.23± 0.23 Bq/l. The highest value of activity concentration for gross αβ radionuclides was reported in samples Emin05 (CRISTALINE) 2,4 Bq/l. The mean values of radiological hazard such as risk assessment (RA) and annual committed effective dose (AED) from this work were within the dose criteria limits given by international organizations (ICRP and UNSCEAR) and national standards. Conclusion: Based on the obtained results in this study, these drinking waters are safe for human consumption even if the risk (stochastic effect) associated with internal exposure due to low dose intakes exists. Based on obtained values, the probability of someone dying of cancer due to the ingestion of these drinking waters is less than 10-5 in the Malian population.
