Environmental radiation monitoring around the Tokai Reprocessing Plant has been performed since 1975, based on "Safety Regulations for the Tokai Reprocessing Plant, Chapter VII - 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 1993. Appendices present comprehensive information, such as monitoring program, monitoring results, meteorological data and annual discharges from the plant.

Generally speaking, two kinds of water plumes which have different temperature, salinity and so on are not easily mixturred and have special boundary. So, it is possible to predict ocurrence of special boundary of sea water from observation of temperature, salinity of sea water. Not only marine environmental monitoring such as radioactivity analysis of sea water, sea-bed sediment, marine products but also observation of water current, water direction, surface and ventical observation of water temperature, salinity and so on in Tokai coastal area are carried out with some observation instruments by Environmental Protection Section, Tokai Works, PNC. The results of vertical observation from 1990 to 1991 are recorded in this report.

An accident has occurred at the Chernobyl atomic power station, USSR on April 26, 1986. By this accident, a lot of radioactive debris was released into the atomosphere, and in all parts of Japan, as well as European countries, that debris was observed in the rain, airborne just and other environmental samples. This report presents a summary of the environmental monitoring performed at O-arai Engineering Center for the period of April 30 - July 4, 1986. Furthermore, preliminary estimation of commited dose equivalent to the public in O-arai area is included.
