Radiation Emergency meaning
Published by a LexisNexis Energy expert
What does Radiation Emergency mean?
In legal practice, a radiation emergency is an incident involving ionising radiation that could expose the public above set dose thresholds and so triggers statutory emergency planning, notification and public information duties.
In Great Britain it is defined in regulation 2 of the Radiation (Emergency Preparedness and Public Information) Regulations 2019 (REPPIR 2019) as an event (other than a pre-existing event) likely to result in any member of the public being exposed to ionising radiation from that event in excess of the doses in Schedule 1. Northern Ireland mirrors this definition in the 2019 Regulations.
In Ireland, analogous provisions under the Radiological Protection Act 1991 (as amended) and S.I. No. 30/2019 (implementing the EU Basic Safety Standards) refer to radiological or nuclear emergencies and emergency exposure situations; the practical triggers and planning objectives are broadly consistent.
Typical use and significance: hazard evaluation and consequence assessment by dutyholders at nuclear and non-nuclear sites; on-site emergency arrangements; determination of off-site emergency planning areas by the local authority; prior and emergency public information; urgent notification to the regulator (HSE/ONR in Great Britain, HSENI in Northern Ireland, EPA in Ireland); and periodic testing and review of plans.

PRACTICE NOTES
Health and safety in nuclear decommissioning: legal framework, regulators' interfaces, emergency planning and post-Brexit/assimilated law developments
What is the impact of Brexit on the UK nuclear sector? As of 31 January 2020 (exit day), the UK ceased to be an EU Member State. From that date, a transition/implementation phase applied, during which the EU continued, for many purposes, to treat the UK as if it remained a Member State. Leaving the EU also entailed withdrawal from the Euratom Community. The transition ended at 11 pm (GMT) on 31 December 2020—known in UK law as ‘IP completion day’. At that point, key transitional measures expired and notable shifts started to apply across the UK’s legal framework. The UK’s exit from the EU likewise meant departure from Euratom. Any changes pertinent to this content are outlined below. Following IP completion day, the European Union (Withdrawal) Act 2018 (EU(W)A 2018) introduced a new category of domestic law—‘retained EU law’ (REUL)—comprising EU-derived rights and legislation preserved in the UK after Brexit. On 29 June 2023, the Retained EU Law (Revocation and Reform) Act 2023 (REUL(RR)A 2023) received Royal Assent...
