Code of Practice on the Application of the Ionising Radiation Regulations (IRR19) in Dentistry 2019

Dr Jane Renehan at Dental Compliance Ltd recommends the EPA’s new dental code of practice as essential reading for all dentists and dental team members. Jane was the dental technical expert on the EPA’S working group which wrote this code.

The EPA holds regulatory responsibility for workers and members of the public and this new code of practice is a helpful, practical guide setting out the requirements of the national regulator.

Jane advises that EPA’s remit as legislated for in S.I. No. 30 of 2019 should not be confused with HIQA’s radiation regulatory responsibilities.

HIQA was designated as the competent authority for medical ionising radiation (patients) under S.I. No. 256 of 2018. Refer to for information and relevant publications. Irish legislation provides for two separate competent authorities to act as regulators in oral radiology. Their individual remits are summarised in the table below.
