Gross [alpha] and [beta] activity concentrations in various water from Karaman, Turkey

Natural activity concentrations in water sources are necessary to assess the effects of exposure to environmental radiation. The purpose of this study is to determine the activity concentrations of gross [alpha] and [beta] in various water samples collected from 30 different locations in Karaman province, Turkey. The estimated values of activities of gross [alpha] and [beta] obtained from water samples vary from 0.006 to 0.125 Bq L^sup -1^and from 0.001 to 0.667 Bq L^sup -1^, respectively. The gross [beta] activities have been found always higher than the corresponding gross [alpha] activities for all samples. The obtained values indicated that concentration levels of [alpha] and [beta] emitting radionuclides in samples have not exceeded WHO recommendations. The results represented here that the AED values are below of recommended reference level (0.1 mSv year^sup -1^) by the WHO for all water samples in this study.
