Graded Authorisation

National Regulations covering the safe use of ionising radiation have recently been updated.  The new Regulations (IRR19) replace the licence based authorisation system (based on S.I. 125 of 2000) with a graded approach comprising both registration and licensing.

In Ireland, in order to legally carry out any practice involving the use of radioactive sources or equipment such as X-ray, which produces ionising radiation, it is necessary to obtain an authorisation (currently in the form of a license) in advance from the EPA, unless the practice has been specifically exempted.  Before authorising a practice the EPA must assure itself that the practice itself has been justified, that the risks have been adequately assessed and that appropriate control measures are in place.

The new Regulation will provide for two forms of authorisation: registration and licensing.  The form of authorisation, which will apply in given situation, will depend on the magnitude and likelihood of any exposures resulting from the practices and the impact that regulatory control may have in improving radiological safety.  Practices, which will be subject to registration are listed below.  All other practices will be subject to licensing.

Practices subject to Registration

Sector Practice
Medical   General radiography giving rise to a medical exposure in a medical radiological installation.  Note that CT, fluoroscopy, interventional and mobile X-ray remain subject to licensing.
Bone densitometry giving rise to a medical exposure
Mammography for health screening in a medical radiological installation
Specimen radiography for medical purposes
Dental   Dental radiography using a fixed intra/extra oral unit  
Dental cone beam CT in an risk assessed clinic
Veterinary  General veterinary radiography carried out in a risked assessed veterinary clinic
Industry   Product inspection/industrial radiography using cabinet X-ray systems
