Health physics in JAERI No.36. (April 1, 1993 ∼ March 31, 1994)

In the annual report No.36(fiscal 1993) are described the activities of health physics in Tokai Research Establishment, Naka Fusion Research Establishment, Takasaki Radiation Chemistry Research Establishment, Oarai Research Establishment, Mutsu Establishment and Nuclear Ship Mutsu. In all the establishments, radiation monitoring in nuclear facilities, individual monitoring, environmental monitoring and maintenance of monitoring instruments were carried out as in the previous years. There were no occupational exposure exceeding the effective dose equivalent limit and no release of radioactive gaseous and liquid wastes beyond the release limits specified in the regulations. In the environment, no abnormal radioactivity was detected attributable to the facilities. Technology developments were made as in the previous years for improving the techniques and methods of monitoring of individuals, facilities and environment, and also radiation measurement instrumentation. The research works were carried out in various fields such as radiation dosimetry, environmental monitoring, and so forth. (author)
