One of the vital missions of the Hong Kong Observatory is to monitor the environmental radiation level in Hong Kong. Amongst other work, the Observatory, in collaboration with the Government Flying Service, conducts regular aerial radiological surveillance. We will also conduct emergency exercise every year to simulate the prompt monitoring of aerial radiation level in the unlikely event of a nuclear incident. The latest episode of "Cool Met Stuff" tells you in detail.
