Title Trend of occupational radiation exposure at nuclear power plants
Bibliographic information Mar. 1983, Vol.25, No.2, p.61-69. Illus. 18 ref.
Abstract 24 nuclear power reactors are in operation in Japan. Trends were derived for 1970-1980 from annual statistical summaries. Individual exposure has been well controlled below the occupational dose limit (5rem/year). The collective dose has been increasing with plant age, and there is a noticeable difference in collective dose among reactor types. The proportion of outside personnel has been gradually increasing. In 1980, 89% of workers and 93% of the total collective dose were accounted for by such personnel. Maintenance and repair are the main causes of occupational exposure. To achieve as low a level of exposure as practicable, reactor and plant design, automation and remote control, and radiation protection training all require attention.
