Radioactive material in the form of sealed sources which has come to the end of its useful life or is no longer required is returned to the original suppliers in accordance with the licensing requirements of the Radiological Protection Institute of Ireland. The location and manner of the final disposal is the responsibility of the original supplier as directed by the national regulatory authority and is not a matter for my Department. Accordingly no information is available on whether any waste from Ireland is ultimately disposed of at Drigg. No waste from Ireland is transported directly to Drigg.
Most of the material in question comes from Canada, the remainder comes from the US, UK and other EC states. Most of the sealed radioactive sources returned to the UK in recent years have come from two Irish hospitals where they were used in the treatment of cancer. The remainder came from a variety of industrial locations throughout the country and a few third level educational establishments.
