Database on Discharges of Radionuclides to the Atmosphere and Aquatic Environment

Regulatory limits are given whenever available and supplementary information about the facility (country, geographical coordinates, water body into which radioactivity is released, number, names and types of installations) is also included.

DIRATA serves to Member States as a technical means for reporting and reviewing within the framework of the Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management.

DIRATA provides:

- tools for input of the primary information by IAEA Member States and international organizations in batch or interactive (record by record) modes. The Microsoft Excel template is provided on the DIRATA website for the batch input;

- on-line access of Member States and the public to the dataset. The information contained in DIRATA is available for downloading (in CSV format) and interactive review.
