Abstract

The ANVS tasked RIVM to regularly perform a check on a subsection of the measurements which are carried out by the Nuclear Research and Consultancy Group (NRG) on samples taken in the vicinity of the Borssele nuclear power plant (NPP).
The NPP Borssele commissioned NRG to carry out monthly sampling of air dust, grass, water (+ suspended solids), seaweed, sediment, and yearly sampling of sand near the cooling water outlet. All these samples were taken by NRG on July 3rd around the NPP Borssele on fixed locations as described in an environmental monitoring programme. All analyses were carried out by NRG.

In 2023 various samples were separately collected on July 5th, and analyzed by RIVM in the laboratory in Bilthoven.

NRG and RIVM both analyzed environmental samples for gamma-emitters, gross alpha and gross beta activity, and water samples for 3H. The analytical results indicate that, in the samples taken by NRG on 3rd and by RIVM on 5th July 2023, no radiological contamination as a result of business operations from the nuclear power plant can be found.
