LSU Services

Every staff/student working on any open-beam x-ray or unsealed radioactive substances are considered as a radiation worker in the CityU. Radiation worker must register to LSU, complete the medical examination and apply for a thermoluminescent dosimeter (TLD) badge to monitor the radiation dose absorbance. LSU provides one-stop service to radiation workers for the arrangement of medical examination and registration to the Radiation Board. LSU serves as a logistic hub in delivering the TLDs to and from the Radiation Health Division of the Department of Health on monthly basis.

If you have any enquiries on returning TLDs, please contact Mr Wheat MAK at 3442 8757 or email tszhomak@cityu.edu.hk.
