Ionising Radiation (Medical Exposure) Regulations (IR(ME)R)

Page last updated: 20 September 2023


Appropriate UK enforcing authorities

To submit a notification, the appropriate IR(ME)R enforcing authorities are:


Care Quality Commission: IR(ME)R notification


Healthcare Inspectorate Wales 


Northern Ireland:

The Regulation and Quality Improvement Authority 

Healthcare Improvement Scotland


Reporting device-related incidents

Where there are risks to individuals relating to medical devices, employers should consider reporting all device and medicine-related incidents to other agencies including:

England and Wales:

The Medicines and Healthcare products Regulatory Agency (MHRA)


Health Facilities Scotland

Northern Ireland:

The Northern Ireland Adverse Incident Centre

It is good practice for employers to report this type of incident (even if they have not resulted in a SAUE). This enables the UK Competent Authority for the Medicines and Medical Device Regulations (MHRA) to take appropriate action with the manufacturer.

Public or occupational exposures

Where a member of the public or a worker receives an over-exposure to ionising radiation, this needs to be reported to the Health and Safety Executive under Regulation 26 of The Ionising Radiation Regulations 2017.

Over-exposures resulting from equipment faults before the equipment is put into clinical use, for example for critical examination, should also be reported to the Health and Safety Executive.
