Radiation Control System
The RCS was officially launched on 1st July 2022, which serves as an electronic platform for the users to purchase radioactive substances and irradiating apparatus. You may find the system in the CityU service portal.
Eligibility of using RCS
Only the staff and research students who are approved by their Principal Investigator (PI) and recommended by the Departmental Radiation Protection Officer (DRPO) are eligible to apply for the purchasing delegate by filling the forms below:
- Nomination Form for radioactive substance purchasing delegate
- Undertaking Form for student nomination RCS Form 2
Please complete the form and return it to the Laboratory Safety Unit at MMW 1434 (Attn. to Mr Terry LEUNG or Mr WL CHAN) to arrange the RCS training and the quiz.
Those who pass the quiz will successfully register as an RCS purchasing delegate.
Undergraduate students are NOT allowed to be the RCS purchasing delegate.
Coverage of the RCS
The RCS controls the purchase and storage of sealed and unsealed sources of a radioactive substance (e.g. Phosphorus-32, Sulphur-35, Iodine-131, etc.) and irradiating apparatus (e.g. X-ray, microCT, etc.).
To facilitate the users’ understanding of the workflow in the system, LSU has prepared THREE separate user guides.
- RCS Unsealed Source Instruction Manual
- RCS Sealed Source Instruction Manual
- RCS Irradiating Apparatus Instruction Manual
New Radioactive Substance
All users must inform the Radiation Board (RB) of the Department of Health (DoH) to add new unsealed or sealed source radioactive substances to the licence before raising any purchase request. Once the updated licence is ready, please send a copy to LSU for adding the new item to the RCS.
If you have any questions or need technical support on the RCS, please do not hesitate to contact us at lsu.radiation@cityu.edu.hk or contact Mr Wheat MAK at ext. 8757.
