In 2009, the DIAL was involved in a Phare project aimed at providing a high level of protection for workers, the public and the environment at the risk of ionizing radiation and also establishing and developing a harmonized approach and regulatory control scheme for NORM activities (natural radioactive materials) and TENORM (technologically enhanced natural radioactive materials).

As a result of the implementation of this project in 2012, a Regulation on radiation protection for activities with materials with increased content of natural radionuclides enters into force in Bulgaria.
