FAQs
No. GRWs are registered with SHENA once only; there is no requirement for expiration or renewal.
Yes. The current licensee must notify SHENA regarding the termination of the GRW’s employment, which will lead to the individual’s removal from the registry. Following this, the new licensee must submit a new registration application for the GRW at the new company.
For the template of the Official Termination Letter, please refer to the Guidelines on Radiation Protection Programme (RPP) Requirements Rev. 1.
Temporary workers who will be in Brunei Darussalam for a duration less than one year are not required to undergo complete registration as GRWs. However, prior to their entry, the employing company must notify SHENA and submit the following documentation:
a) A copy of the worker’s passport;
b) Competency certification;
c) The worker’s most recent dose record; and
d) A letter of authorisation permitting the worker to undertake radiation-related work in Brunei Darussalam.
The company remains wholly responsible for ensuring the radiation safety and protection of the temporary worker throughout their assignment in Brunei Darussalam.
There is no maximum age limit established; however, the minimum age requirement is 18 years. It is essential that the RPO demonstrate ongoing competence and fitness to effectively perform the roles and responsibilities associated with the position.
Only one RPO shall be officially registered with SHENA per licence. Nevertheless, the licensee may designate an internal backup RPO within the organization, provided that the individual is a registered General Radiation Worker (GRW) and is deemed competent by the licensee to assume the roles and responsibilities of the RPO in their absence.
The validity of existing registrations will not be affected. For example, if an RPO registration is valid until 2027, it shall remain valid until its original expiration date in 2027.
