Report on Administrative Work at Radiation Safety Center in fiscal year 2003

Date of publication:

June 2005

Key words:

radiation protection and safety management, magnetic fusion plasma, LHD, X ray, radiation measurement and monitoring


National Institute for Fusion Science constructed Large Helical Device (LHD) which is the largest magnetic confinement plasma experimental device using super conductive magnet coils system. It took eight years to construct and the first plasma shot was carried out on March 1998. Since then high temperature plasma and improved plasma confinement experiment have been achieved. This is the report on administrative work at the radiation safety center considering radiation protection for workers at the LHD and the Compact helical Device(CHS), and radiation meassurement and monitoring in the site. Major scope is as follows. (1) Radiation (X ray) dose measurement and monitoring in the radiation controlled area and in the site using particularly developed monitoring system named as Radiation Monitoring System Applicable to Fusion Experiments (RMSAFE). (2) Establishment of education and registration system for radiation workers and accessing control system for the LHD controlled area. As same as the published annual reports from fiscal year 1999 and 2002, this report will be helpful for the future radiation safety management in the research institute.
