Why your views matter

The current code for dental radiology was published in June 2018. It is secondary legislation and applies to any person who deals with a radiation source. Deal with is interpreted in the Act and includes to manage, control, use, sell, and supply a radiation source.

The target audience for this consultation includes all regulated parties that will be affected by the C4 Code and other persons, or organisations involved with dental radiology. 

All feedback received will be reviewed and will inform the revision of the C4 Code.

What happens next

The Office of Radiation Safety will analyse the feedback and provide comments on the outcome of the analysis before publishing the C4 Code.

We are aiming to complete the review of the final code of practice for non-medical irradiators for implementation by the end of 2019.
