226Ra, 228Ra and 40K radioactivity were analyzed and their radiotoxicity were assessed in drinking water samples collected from groundwater wells in El-Beheira governorate, Northwestern of Egypt. The average activity concentration of 226Ra,228Ra and40Kvalues in the study areas 4.59, 0.583 and 7.187 Bq/l, respectively. Three wells only were complying with WHO (2011) guidance level for 226Ra radionuclides for members of the public (1 Bq/l).The total annual effective doses radiation during water consumption for (226Ra,228Ra and 40K ) in the study areas for adults estimated to range from 0.208 to 3.716 mSvy-1 , which are much higher than the reference level of the committed effective dose recommended by the WHO (0.1 mSvy-1).Properactions must be taken to treatment the groundwater from radionuclides in this areas to protect the population in the study areas. Additionally, Fe, Mn, Zn and Cu trace meals were measured in the same samples and their chemotoxicity were assessment. Theaverage concentrationare0.35, 0.45, 0.08 and 0.05mg/l,respectively.The majority of the studied wells fortrace meals complying with Egyptian permissible limit .Risk assessment due to intake of heavy metals around study areas where hazard quotient and hazard index is less than 1 meaning that no significant risk or systemic toxicity on the exposed population.
