Criteria for making a notification

The following tables detail the criteria for notifying the appropriate enforcing authority of a significant accidental or unintended exposure.

Notes: As well as the changes to criteria, we have improved the layout of the table to make the footnotes easier to read.

In England only, there are age-related dose thresholds for notifications of accidental exposures.
