Research Outline

In order to evaluate the safety management for workers in nuclear power-related facilities and their impact on the surrounding area, the development of radionuclide analysis methods in biological and environmental samples is an important issue. However, the accidents at TEPCO's Fukushima Daiichi Nuclear Power Station and the Japan Atomic Energy Agency show that the latest research trends have not been implemented the site. In this research, we will advance both technical development and implementation of solid phase extraction and ICP mass spectrometry. In addition to the development of analytical technique by developing automatic analyzing system, we aim to establish international standards for analytical methods. 
Environmental water samples such as river water and tap water, which are important for evaluating oral exposure, and biological samples such as nails, hair, and urine samples are analyzed to estimate the amount taken up into the body. The analytical method developed in collaboration with the National Physical Laboratory in UK will be proposed as a new international standard by the International Organization for Standardization. The automated chemical separation system will be developed, which can ensure the reliability of analysis results and promote implementation of proposed methods.
