Environmental contamination with alpha-emitting nuclides of uranium and transuranium elements is possible during accidents involving nuclear devices or nuclear power plants. There is a concern regarding uranium concentration after the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) accident. Therefore, monitoring of uranium concentration from its different forms, present in river water is of great significance. Japan is divided into 47 prefectures involving more than 30,000 rivers, streams and lakes collectively. In the present work, radioactivity levels of 238U in 38 river water samples were checked from the viewpoint of water quality and radiation protection. Measurement of 238U concentrations were carried out using inductively coupled plasma mass spectrometry (ICP-MS). The detection limit for 238U is 0.03 ng/L in ICP-MS measurements. The concentration of uranium ranges between 0.13 ± 0.002 – 2266.53 ± 0.006 ng/L in our study. Dose effects will be discussed during presentation., 9th International Conference on High Level Environmental Radiation Areas-For Understanding Chronic Low-Dose-Rate Radiation Exposure Health Effects and Social Impacts (ICHLERA 2018)}, title = {DISTRIBUTION OF URANIUM IN SELECTED JAPANESE RIVER WATER}, year = {2018} }
