Environmental radiation monitoring around the Tokai Reprocessing Plant has been performed since 1975, based on "Safety Regulations for the Tokai Reprocessing Plant, Chapter IV - Environmental Monitoring". This annual report presents the results of the environmental monitoring and the dose estimation to the hypothetical inhabitants due to the radioactivity discharged from the plant during April 1999 to March 2000. Appendices present comprehensive information, such as monitoring program, monitoring results, meteorological data and annual discharges from the plant.

The meteorological observation has been performed since 1955 in PNC Tokai-works. After 1974, this observation came to measure on the top of the meteorological tower (100m above sea level) for the environmental assessment of a radioactive waste with the atmospheric discharge from the reprocessing plant. This report presents an atmospheric phenomenon statistic result and an examination about a characteristic of the atmosphere diffusion based on the data from 1977 to 1995. Characteristics of the result are as follows; (1)It was confirmed that the maximum air concentration point that was calculated based on the discharge amount from reprocessing plant and atmospheric phenomenon statistic of each year appears at near point in the safety assessment of 1977. (2)In some case, a maximum concentration point has appeared at about 800m in the west-southwest direction owing to the deference of appearance frequency of the atmospheric stability, etc. Normally it appears at about 2,000m point in south-west direction. Still, as reference materials, atmospheric phenomenon statistics result and relative concentration were mentioned.
