Notifying IR(ME)R incidents

  • Organisations we regulate

Employers must tell us about exposures judged to be ‘significant’ or ‘clinically significant’ accidental or unintended exposures.

The Ionising Radiation (Medical Exposure) Regulations 2017 and the Ionising Radiation (Medical Exposure) Regulations (Northern Ireland) 2018) are designed to protect people while undergoing examinations and treatment using ionising radiation.

When there is an accidental or unintended exposure to ionising radiation, and the IR(ME)R employer knows or thinks that it is significant, they must investigate the incident and report it to the appropriate UK IR(ME)R enforcing authority (under Regulation 8(4)).

This guidance tells you which incidents you need to report. It replaces the previous guidance on investigation and notification of medical exposures much greater than intended (MGTI) under IR(ME)R 2000, and is jointly agreed by the English, Welsh, Scottish and Northern Ireland enforcement authorities.

Make an IR(ME)R notification

Use the incident report form.

IR(ME)R incident report form

To bookmark the form for future notifications, bookmark this page and not the link for the form itself. This makes sure your report has a unique reference number.

What happens next?

After you submit the form we will send you an email containing your IR(ME)R notification reference number. Use this reference number whenever you contact us. If you do not see the automated email, check your junk email folder.

Inspectors no longer acknowledge individual notifications, but we may contact you to ask about any details you have provided. Otherwise, we will wait until you have submitted your full report before we review it.

When you have completed an investigation report, send it to the address below within the timeframe stated in the guidance. The report must be anonymised and include no patient identifiable information in line with GDPR.
