How many cyclotrons are there in Hong Kong?

As of my last update, Hong Kong has a few cyclotrons primarily located in medical and research institutions. Notably, the Hong Kong Sanatorium & Hospital operates a cyclotron for producing radiopharmaceuticals used in positron emission tomography (PET) scans. Additionally, the University of Hong Kong and other research facilities may have cyclotron facilities. For the most current information, it's best to consult local resources or institutional websites.
