Scientific Program

The Conference aims to take stock of the worldwide radiation safety situation. It will provide a forum for the exchange of information on Member States’ experiences in applying the system of radiological protection, as provided for in the IAEA safety standards, to the protection of workers, patients, the public and the environment. Both natural and artificial radiation sources fall within the scope of the Conference.

A particular focus will be given to the lessons learned from applying GSR Part 3 and improvements that could be considered to further facilitate its application. Discussion on changes in approach considered necessary for effectively dealing with new and emerging challenges in radiation protection is expected and encouraged.

The Conference has been scheduled to allow for input from the 5th International Symposium on the System of Radiological Protection, which was organized by the ICRP and took place in Adelaide, Australia, from 17 to 21 November 2019 and from the 15th International Congress of the International Radiation Protection Association, which will take place in Seoul, Republic of Korea, from 11 to 15 May 2020.

In preparing the programme for the Conference, the views of Member States were sought through regional workshops organized in Argentina (for the Americas region), Cyprus (for the Europe region), Singapore (for the Asia and the Pacific region) and the United Republic of Tanzania (for the Africa region). These workshops identified the key implementation issues in each region that would benefit from detailed discussion at the international level.
