Medical Exposure Radiation Unit

The Department of Health is the designated competent authority for patient radiation safety, under statutory instrument (SI) 478

(2002), for regulating medical ionising radiation in Ireland and the National Radiation Safety Committee (NRSC) is

the statutory committee established under this legislation. 

The responsibility for patient radiation protection has been delegated to the Director General (DG) of the HSE who

nominates relevant experts in radiation safety to become members of the NRSC and provide advice on matters pertaining

to medical ionising radiation exposure.


The HSE Medical Exposure Radiation Unit (MERU) was established to regulate patient radiation protection practices in both

public and private radiological facilities, and is the executive, administrative and advisory unit for the NRSC. 

The Office of Radiation Protection and Environmental Monitoring (ORPEM), is the competent authority and regulates radiation

protection practices for workers and members of the public under (SI) 125 (2000). www.epa.ie

In 2018, the Competent Authority and regulatory functions will transfer to the Health Information and Quality Authority.

Manage the mandatory incident reporting system.

Develop and provide guidance to holders, practitioners, other staff and statutory bodies on relevant matters as guided by the NRSC.
