This Order, made under Section 30(2) of the Radiological Protection Act of 1991, provides for the implementation of Council Directive 2003/122/EURATOM on the control of high-activity sealed radioactive sources and orphan sources. It, among other things: defines the Radiological Protection Institute of Ireland as the competent authority to carry out tasks in accordance with this Order and the Council Directive; requires a person who is responsible for a source ("holder") to obtain prior authorization from the Institute under a licence for any practice involving a source including taking possession of a source; requires a holder to keep records; and requires a manufacturer to identify or, in the case of sources imported from outside the Community, a supplier to ensure that each source is identified by a unique number.
