摘要: The present work investigated the radioactivity level of granitoid plutons and its effect on groundwaters in southeast part Eskisehir. Fourteen granitic samples from Kaymaz Sivrihisar 11 groundwater near vicinity pluton were analyzed. activity concentrations measured for (238)U (232)Th ranged 43.59+/-2 to 651.80+/-24 Bq/kg, 51.16+/-3 351.94+/-13 respectively. obtained (40)K varied 418.50+/-17 1618.03+/-66 Bq/kg. absorbed dose rates air outdoors 87.14 531.81 nGy/h. All results are higher than those Sivrihisar. U (ave. 16.6 ppm) Th 49.9 values average magmatic rocks composition. These consistent with high pluton. gross-alpha activities 0.009 1.64 Bq/l gross-beta 0.006 0.89 Bq/l. highest value was found sample taken (222)Rn 0.060 0.557
