Radiation Protection Adviser (RPA) Register

The register includes the RPA name and the expiry date of their approval.  For RPAs who provide an RPA service to third party undertakings, contact details have also been included.  While every effort has been made to ensure that the contents are accurate, the EPA does not accept legal liability for any errors or omissions.  Persons intending to rely on these listings should make their own enquiries to ensure that their proposed RPA appointee is willing to provide RPA services appropriate to the requirements of the client.
