Advice to people in response to a radiation emergency

There are a number of potential risks to the public from exposure to ionising radiation or the spread of radioactive material within the environment from any radiation emergency within Suffolk. A range of guidance documents have been used to cover the different risks in the development of effective radiation emergency arrangements. There also exist potential risks from an incident involving the transport of radioactive material covered by the Carriage of Dangerous Goods (Amendment) Regulations 2019, and the risk from the unlikely event of a radiation emergency, including those arising out of terrorist acts, during the transportation of defence nuclear weapons and Special Nuclear Material. These form the basis of the radiation emergency Plan.

An incident at Sizewell power station may cause an increased risk to public health and require specific countermeasures to be put into place by the emergency services. A range of information has been produced to help you understand what might happen if an incident occurs.

Suffolk County Council lead on the planning for an off-site incident at Sizewell B.  This plan is written in accordance with the Radiation Emergency Preparedness and Public Information Regulations 2019 (external website).  The public version of the Radiation Emergency Plan sets out the multi-agency strategic and tactical management arrangements for dealing with a nuclear emergency (i.e. an incident with off-site radiological implications) at Sizewell B Nuclear Power Station.

What to do post-incident

Hazard and Risk Assessments

Each Sizewell operator is required to identify the hazards and evaluate the risks from the work with ionising radiation that they propose to carry out and to make such assessments available to the public. These assessments are used to identify reasonably foreseeable accident scenarios. With the agreement of the Sizewell operators, the following assessments are available:

  • Sizewell A Site: Report of Assessment
  • Sizewell B Power Station: Report of the Assessment
