Introduction of radionuclides (HOLAS 2)
Short description
Introduction of radionuclides is based on HELCOM MORS Discharge data from 2011 to 2014. The isotopes taken into account were: Cesium-137, Strontium-90, and Cobalt-60. The decay-corrected annual average of the sum of the radionuclide discharges (in Bq) were calculated for the pressure. 10 km buffer with linear decreasing function was used to represent the impact distance from the nuclear power plant outlets.

Lineage
Data source: See separate fact sheet on Discharges of radioactive substances from NPPs. Data quality: The annual discharges of radioactive substances were reported from all of the operational nuclear power plants. Some gaps may occur in the radioactive discharge data. Attribute information: Introduction of Cesium-137, Strontium-90, and Cobalt-60 in Bq Spatial coverage: Entire Baltic Sea. Spatial resolution: Original data as points, 10 km impact distance applied from the outlets and finally converted to 1 km x 1 km grid.
