Radiation Board Policy on tritium self-luminous signs |
(A) |
The use of tritium signs is only justified by the potential benefit of saving of life and where the use of electrical power is not possible or feasible; |
(B) |
If the aggregate activity of tritium in signs that are securely fixed at specified locations inside any specified premises is 1,000 GBq or less, user / possessor of tritium signs may be granted an exemption which is renewable triennially so that the administrative burdens to the Board can be reduced without unduly compromising the health and safety of the public; |
|
(C) |
If the aggregate activity of tritium in signs that are securely fixed at specified locations inside any specified premises exceeds 1,000 GBq, the end-user / possessor of tritium signs shall be bound by licence so that the status of management and condition of the signs are reassessed annually; |
|
(D) |
Importers, manufacturers, producers, distributors and sellers of tritium signs should be subject to licence requirements so that the health and safety of workers and directly affected members of the public will be adequately protected and the transfer and disposal of tritium signs will be kept under proper management from "cradle to grave", so as to minimize the potential exposure of indirectly affected members of the public to tritium; |
(E) |
No local disposal of tritium sign is permissible. All such signs are to be returned to the overseas manufacturer when they can no longer serve the dedicated purpose of usage. |
