Authorisation by SHENA is required to import and export radioactive material and/or controlled apparatus in Brunei Darussalam. This is done by submission of the authorisation form (signed by RPO/licensee) to SHENA along with the required supporting documents. SHENA will email the approved authorisation form to the Licensee, who then submit the approved authorisation form through Brunei Darussalam National Single Window (BDNSW) for permit endorsement.
