This annual report describes the activities of Department of Radiation Protection in Nuclear Science Research Institute in the fiscal year 2005. The report covers environmental monitoring around the facilities, radiation protection of workplace and workers, individual monitoring, maintenance of monitoring instruments, and research and development of radiation protection technologies, which were performed at Nuclear Science Research Institute, Tokai Research and Development Center, Japan Atomic Energy Agency. There were no occupational or public exposures exceeding the prescribed dose limits. No effluent releases were recorded exceeding the prescribed limits on the amount and concentration of radioactivity for gaseous release and liquid waste. As for the research and development activities, studies were conducted focusing mainly on the following themes: technological developments on operational radiation protection and establishment of calibration fields for various types of neutrons.
