Radiation Monitoring Services

The RHD provides a centralized personnel radiation monitoring service to all radiation workers in Hong Kong. The service includes the exchange, on a monthly basis, of radiation dosimeters to employers who subscribe to the service; the maintenance of the dosimeters; assessment of radiation dose recorded on the dosimeters which the workers carried in the previous month, reporting on the doses and alerting the employer in the event of high doses. The objective of the service is to provide a means to monitor the radiation exposure received by workers with a view of limiting their overall exposure to a reasonably acceptable level and within the limits prescribed by law.
