ESS - Large-scale survey program

ESS logotype

In a collaboration project between Medical Radiation Physics Malmö and the Division of Nuclear Physics at Lund University, we have carried out a large-scale survey program of the radiation environment around the European Spallation Source (ESS).

The aim was to establish the current levels of ionizing radiation and concentration of various radionuclides, natural as well as artificial, in the surroundings of ESS prior to start of operation of the facility. The data generated, during 2017-2018, may be used to determine future potentially unobserved and diffuse discharges from ESS to the environment. Such comparisons can also provide information of possible long-term changes in the radionuclide concentrations in the environment as well as assessments of the exposure to the public before and after operation of ESS. 

The report “assessment of zero point radiation around the ESS facility” can be found at:…

A folder summarising the measurements, were distributed to the public around ESS. That folder may be found at: 

The monitoring program should continue for longer time periods in order to include seasonal variations in the radiation environment and radionuclide concentrations and uptakes. For that reason, the project was renewed as a framework agreement in 2020 to be carried out during four years. More details and annual reports can be found here:
