Ionising Radiation (Medical Exposure) Regulations (IR(ME)R)
Assessing the dose
We use ‘effective dose’ to define what is notifiable for some categories (see Notification codes, categories and criteria)
The effective dose is the principal dose parameter, including for radiotherapy planning and verification imaging. However, where it is difficult to assess the effective dose or where alternative dose units are more relevant, the notification form allows you to add this information in the relevant section.
The report should include an assessment of intended and unintended dose to the patient(s).
