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.

This report is a revised edition of "Isopleths of Surface Air Concentration and Surface Air Absorbed Dose Rate due to a Radioactive Cloud Released from a Stack(II)"(JAERI-M 90-206) and based on the revised Nuclear Safety Guidelines reflected the ICRP1990 Recommendation. Characteristics of this report are the use of Air Karma Rate (Gy/h) unit instead of Air Absorbed Dose Rate (Gy/h) unit, and the records of isopleths of surface air concentration and surface air karma rate on CD-ROM. These recorded data on CD-ROM can be printed out on paper and/or pasted on digital map by personal computer.

The nuclear facilities, which are required to control the released radioactive gases and liquid, exist in Tokai research establishment as much as 40. These radioactive controls are carried out complying with the statutes in each facility. The released radioactivity data of each facility must be reported to MEXT and Ibaraki Prefecture from Tokai Research Establishment. This system is developed to make the database gathering the radioactivity data of each facilities for unitary control as Tokai Research Establishment and contribute to make the reports to MEXT and Ibaraki Prefecture.

The meteorological observation data at Tokai site were analyzed statistically based on a "Guideline of meteorological statistics for the safety analysis of nuclear power reactor" (Nuclear Safety Commission on January 28,1982; revised on March 29, 2001). This report shows the meteorological analysis of wind direction, wind velocity and atmospheric stability etc. to assess the public dose around the Tokai site caused by the released gaseous radioactivity. The statistical period of meteorological data is every 5 years from 1981 to 1995.

The national and local governments, and the nuclear enterprises have strengthened nuclear disaster measures since the JCO criticality accident in 1999. This report shows the renewed radiation monitoring equipment and extended system for functional strengthening of the environmental radiation observation in Tokai site of JAERI.

A computer code (EDAS) was developed to assess the public dose for the safety assessment to get the license of nuclear reactor operation. This code system is used for the safety analysis of public around the nuclear reactor in case of normal operation and severe accident. This code was revised and composed for personal computer user according to the Nuclear Safety Guidelines reflected the ICRP1990 recommendation. These guidelines are revised by Nuclear Safety Commission on March, 2001, which are “Weather analysis guideline for the safety assessment of nuclear power reactor", “ Public dose around the facility assessment guideline corresponding to the objective value for nuclear power light water reactor" and “Public dose assessment guideline for safety review of nuclear power light water reactor". This code has been already opened for public user by JAERI, and English version code and user manual are prepared moreover. This English version code is helpful for international cooperation concerning the nuclear safety assessment with JAERI.

A computer code (W-View) was developed to analyze the meteorological data statistically based on “the guideline of meteorological statistics for the safety analysis of nuclear power reactor"(Nuclear Safety Commission on January 28,1982; revised on March 29,2001), which code is used for statistical analysis of meteorological data to assess the public dose in case of normal operation and severe accident to get the license of nuclear reactor operation. This code was revised from large office computer code and developed for personal computer user to analyze the meteorological data simply and conveniently and to make the statistical data tables and figures of meteorology.

An environmental radiation monitoring system in Tokai establishment of JAERI is composed of 14 monitoring posts, 4 monitoring stations, 2 drainage monitors and the monitoring data observation center. These monitoring posts and stations measure the gamma dose rate, and the monitoring stations measure the radioactive air concentration too. Drainage monitors measure the radioactive concentration in drain water. We developed the environmental radiation dose information system used by cellular phone for observing the monitoring data in day and night, working day and holiday at everyplace in Japan. This information system shows us the every minute or every 10 minutes monitoring data table and data trend graph on the cellular phone display. In the emergency situation, this system helps for speedy response such as the notification to the JAERI staffs, starting the emergency environmental monitoring activities, reporting the dose rate and concentration to the national and local authorities, and establishment of the emergency response team in JAERI.

JAEA was established on October 1st, 2005 by integrating the Japan Atomic Energy Research Institute and the Japan Nuclear Cycle Development Institute. In these institutes, there were a several radiation control methods or original radiation control levels. After establishing JAEA, in order to make a harmonization of radiation control methods and levels, applications of these are investigated under actual situations.
