Ionizing Radiation Safety

Radiation safety is a paramount concern on campus, ensuring the well-being of all staff, students, and visitors. At CityU, strict adherence to the Cap. 303 Radiation Ordinance is essential for maintaining a safe environment when working with radioactive materials or radiation-emitting devices. This ordinance mandates that any use of radioactive substances or irradiating apparatus must be licenced. The application for the relevant license is a critical step in ensuring that all radiation practices meet the legal and safety standards set forth by the ordinance.

In addition to obtaining the necessary licences, it is mandatory for all radiation workers to undergo a medical examination before commencing any laboratory work involving radiation. This medical exam is crucial for several reasons. Firstly, it establishes a baseline health status for the worker, which can be used for comparison in the event of any future health issues related to radiation exposure. Secondly, it ensures that individuals are fit to work with radiation, identifying any pre-existing conditions that might be exacerbated by radiation exposure.

Regular medical check-ups are also part of the ongoing safety protocol, ensuring that any changes in health status are promptly identified and addressed. This proactive approach helps in early detection of potential radiation-related health issues, allowing for timely intervention and treatment.

By adhering to these stringent safety measures, CityU demonstrates its commitment to creating a safe and healthy working environment. The application of relevant licenses under the Cap. 303 Radiation Ordinance and the mandatory medical exams for radiation workers are fundamental components of the university’s radiation safety program. These measures not only comply with legal requirements but also promote a culture of safety and responsibility, ensuring that all radiation activities are conducted with the utmost care and consideration for health and safety.

Non-Ionizing Radiation Safety

Non-ionizing radiation, such as that from Wi-Fi, Bluetooth and cell phones, is generally considered safe on campus. Unlike ionizing radiation, which can damage DNA and cells, non-ionizing radiation lacks the energy to cause such harm. Regulatory bodies like the World Health Organization and the International Commission on Non-Ionizing Radiation Protection have established guidelines to ensure exposure levels remain well within safe limits.
