Information notice

At their plenary meeting on 7-9 June 2023 held in Stockholm, HERCA’s members elected Jean-Luc Lachaume, ASN Commissioner, as Chair of the association.

During its six-monthly plenary meeting, the Heads of the European radiological protection competent authorities’ Association (HERCA1) elected Jean-Luc Lachaume, ASN Commissioner, as Chair of the association.

Jean-Luc Lachaume, who has served as Chair of HERCA since 2019, replaces Nina Cromnier, former Director General of SSM (Swedish Nuclear Safety Authority), in this position. He will be assisted by two Vice-Chairs, Patrick Majerus, Head of the Radiation Protection Division at the Luxembourg Ministry of Health and Pilar Lucio Commissioner of CSN (Spanish Nuclear Safety Authority). The HERCA’s technical secretariat, which was the responsibility of SSM on a transitional basis since December 2022, will be handed over to ASN.

Jean-Luc Lachaume’s ambition for his new mandate is: to continue implementing the new HERCA strategy, with its main focus being reinforced cooperation between the radiation protection competent authorities and the development of cross-inspections; to actively involve HERCA in the project to overhaul the recommendations of the International Commission on Radiological Protection (ICRP), with the publication of HERCA’s “Reflections on the Revision of the System of Radiological Protection”; and in response to the events in Ukraine, to mobilise as necessary, the group of experts to reinforce and prepare for transboundary cooperation in the event of an accident.

This six-monthly meeting, hosted in Stockholm by the SSM, was also an opportunity for the association to address a number of important topics including: the implementation of HERCA's strategy and revision of its policies; progress on the work of HERCA's six expert groups; Small Modular Reactor (SMR) and radiation protection challenges; and the situation in Ukraine.


  1. In the field of radiation protection, HERCA, founded in 2007, also at the instigation of ASN, is an association of the Heads of the European Radiological Protection Competent Authorities. Its aim is to reinforce European cooperation in radiation protection and to harmonise national practices. Six expert groups are currently working on the following themes: practices and sources in the industrial and research fields; medical applications of ionising radiation; preparedness for and management of emergency situations; veterinary applications;      and natural radiation sources; education and training.
