| 内容記述 | Uranium is one of the heaviest naturally occurring element on earth. 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. | |||||
