Radiological protection of the environment (RPE) has become an established element of the international system of radiological protection (SRP) through the development of international commission on radiological protection (ICRP) concepts such as reference animals and plants (RAPs) and derived consideration reference levels (DCRLs). Despite broad international recognition, implementation of these concepts varies considerably among countries, regulators, operators, technical support organisations, and research institutions.

To better understand current practices and perceptions, the NEA Expert Group on Radiological Protection of the Environment (EGRPE) conducted a global survey in 2026 to assess how RPE recommendations are applied, interpreted, and used in decision-making. The survey gathered responses from regulatory, scientific and operational stakeholders worldwide, and provides valuable insights into current approaches, challenges and future needs.

The joint webinar with ICRP will:

• Present key findings from the EGRPE survey;
• Explore how ICRP RPE recommendations are currently being implemented across different jurisdictions;
• Identify common drivers, benefits and challenges associated with environmental radiological protection;
• Discuss lessons learnt from the practical application of RAPs, DCRLs and supporting assessment tools;
• Consider implications for the ongoing revision of the SRP; and, 
• Gather stakeholder perspectives on future priorities for guidance, training, tools and international harmonisation.

Participants will:

• Gain an overview of current international RPE practices;
• Better understand how RAPs and DCRLs are being used in real-world contexts;
• Identify common implementation challenges and potential solutions;
• Contribute to discussions on future international guidance and harmonised approaches; and,
• Strengthen collaboration among regulators, operators, researchers and international organisations.
