Radiation Ordinance (Cap 303), Laws of Hong Kong, stipulates relevant controls on radioactive substances and irradiating apparatus. The Radiation Board is established for the purposes of the Ordinance.

Applications for licences to manufacture, produce, sell, deal in or with, possess or use radioactive substances or irradiating apparatus should be submitted to the Radiation Board Licensing Office. Depending on the complexity of the case and with timely submission of the necessary documents by the applicant, a licence may be granted in 8 week's time. All licences are valid for 12 months with effect from the date of grant or renewal thereof or for such lesser period as may be specified in the licence.

Relevant Licence must be obtained before taking possession of or undertaking other abovementioned activities involving any radioactive substances or irradiating apparatus. You can submit the application by filling in the application forms (pdf fillable format) for a Radioactive Substances Licence or a Irradiating Apparatus Licence or on-line submit the application via the Electronic Radiation Licensing & Services System (ERLS).
