BAR: Biospheric and Anthropogenic Radioactivity

The research of the BAR group concerns various aspects of man-made radionuclides which may be found in the environment today and in the future.

Our research group focuses on environmental radiology, specifically studying the release of radionuclides from various sources. These sources include nuclear power plants, research laboratories, and accelerator facilities. 

Our work includes collaboration on several fronts, working with man-made radionuclides from several sources:

  1. European Spallation Source (ESS):
    • We investigate radiation levels around the ESS, which is currently under construction in Lund.
    • Our goal is to understand the environment before the facility starts, and prepare for future measurements of ESS-specific radionuclides.
    • Environmental samples (such as crops, water, and aerosols) are part of our analysis.
    • We collaborate with Medical Radiation Physics, Malmö.
  2. Nuclear power
    • We investigate the radiological impact of nuclear power of today and in connection with the possible expansion of nuclear power.
    • The radionuclides 3H and 14C are of particular interest.
  3. 14C Bomb Pulse Dating:
    • We utilize accelerator mass spectrometry (14C-AMS) to study the impact of mid-century nuclear weapons tests.
    • The radioactive carbon isotope 14C serves as a tracer, aiding our understanding of disease development.

In summary, our multidisciplinary team contributes to advancing environmental radiology knowledge.
