Environmental monitoring is implemented around Tokai Reprocessing Plant to ensure the environmental safety. In the terrestrial environment, environmental radiation is measured continuously using a monitoring station, and the concentration of radioactive materials contained in soil and vegetables are also analyzed. In the marine environment, the concentration of radioactive materials contained in sea water, seabed sediment, and marine products are regularly analyzed. The results of the environmental monitoring have been openly published and presented to the public after authorization by outside experts. These monitoring data are available at the following Internet web site :

The levels of external radiation and radioactive materials in the air are continuously monitored by radiation monitoring apparatus in order to ensure safety in the working environment.
Personal monitoring is implemented with the JAEA original designed TLD badge system and other new internal monitoring devices.
Radiation monitoring instruments and dose assessment techniques are also investigated to improve the monitoring performances and applied to the occupational monitoring in nuclear fuel cycle facililies.
