Early phase emergency radiation monitoring

Emergency radiation monitoring in early phase primarily serves the purpose of verifying that there is no significant radioactive plume or deposition over Hong Kong. In case there is an accident resulting in the release of radioactive materials that affects the territory, emergency radiation monitoring will rapidly determine the concentration and distribution of the radioactive materials over the territory for assessing nuclear accident consequences and considering necessary countermeasures.
As it is necessary to obtain timely information, early phase monitoring focuses on the measurement of ambient gamma dose rates, concentrations of gamma-emitting radionuclides and gross alpha/beta levels. To ensure that timely monitoring results can be obtained with minimal personnel exposure, remote sensing technology is applied as far as possible.

Emergency radiation monitoring in early phase includes:
Full activation of instruments in the radiation monitoring network
Conduction of emergency radiological surveys
Stepping up of measurements by the Automatic Gamma Spectrometry System and analysis of results
Conduction of radiation monitoring at designated fire stations
