To ensure that our environment is not adversely affected by the operation of the nuclear power stations at Daya Bay, the Hong Kong Observatory (HKO) implements an environmental radiation monitoring programme since 1987.

The radiation monitoring network consists of 12 fixed radiation monitoring stations, and each station installed a High-Pressure Ionization Chamber (HPIC) which is very sensitive and can detect small changes in radiation level. The collected data and sample will then be further analysed.

In order to further enhance the quality of the gamma radiation measuring service, HKO invited TQM to help to establish a Quality Management System (QMS).

HKO’s ambient gamma radiation level measurement results not only as a protection for HK citizens but also can reflect whether the operation of the nuclear power stations is under safe conditions. The result and the related information are available to the public via the HKO website and various channels.
