NMBU scientists are co-authors of a study by the Norwegian Institute of Public Health (Folkehelseinstitutet, FHI) and published in Nature Communications (1). Together with other studies, the results reported in this paper suggest that current risk estimates for radiation damage may need to be revised.
All radiation can cause breaks in DNA with higher doses causing more damage than low doses. The challenge for regulatory authorities, therefore, has been to define radiation doses that constitute a significant risk for the health of humans and other organisms. The European Commission's latest recommendation from 2013 sets a dose limit for occupational exposure at 20 mGy (milligrays) per year. By comparison, average annual background exposures to radiation are about 3 mGy and a single X-ray exposure at the dentist's office corresponds to about 1 mGy.
