The radiation level in Hong Kong is normal
(15 March 2011)

 
Base on our assessment of the weather situation, the chance of the radiation from Japan reaching Hong Kong in the next several days is slim. The rumor that the radiation will affect Hong Kong is unfounded.

A webpage showing the path of air mass reaching Hong Kong in the next few days clearly indicates that the origin is far from Japan.
