Since the genesis of the earth the Radioactivity is present in the all environment compartments (Air, Soils, waters and vegetations). The level of radioactivity is depending to the geological characteristics and the nature of rock (Volcanic or sedimentary rocks). The paper aim to determine a reference level of natural radioactivity presents in groundwater by using a portable Geiger Muller counter. 8 samples of groundwater were collected. Water samples were acidified and evaporated with hotplate at a constant temperature (60°) until obtaining a small volume (1 liter). Conditioned samples were measured with a Portable Geiger Muller counter (10h). The calculated radioactivity was vary from 0,17Bq/l to 0,19Bq/l and the equivalent dose was vary from 20µS/year to 29µS/year. These results indicate that’s groundwater samples have a low radioactivity and are safe for human consumption.
