REPPIR 2019 - Approved Code of Practice update

The REPPIR 2019 Approved Code of Practice (ACOP) and Guidance contains the Radiation (Emergency Preparedness and Public Information) Regulations 2019 (REPPIR), the Approved Code of Practice (ACOP) and guidance text. It provides supporting good practice guidance for operators and Local Authorities (LAs) about preparedness and response arrangements for radiation emergencies.

The Regulations set out the legal duties and the ACOP and guidance give practical advice on how to comply with those requirements. The publication provides guidance for operators in the evaluation of hazards and assessment of consequences, and for LAs on the duties to establish emergency planning zones and make emergency plans.

The Regulations came into force on 22 May 2019, updating and replacing the previous 2001 regulations. They contain new requirements for emergency planning in particular, defining a radiation emergency, establishing a different basis and responsibilities for determining emergency planning zones, including the addition of Outline Planning Zones, and defining an emergency worker.
This Stationary Office version of the REPPIR ACOP and Guidance replaces the PDF version that was published in September 2019. There is one substantive change to the Guidance Regarding Arrangements for Medical Surveillance from the September 2019 version.
