As Japan battles to bring its renegade nuclear reactors under control, other countries are reviewing their own nuclear power plans.
The 9.0-magtitude quake that hit the islands on March 11, and the resultant tsunami damaged one of the country's nuclear reactors.
New readings show a sharp rise in radioactive iodine present in the sea off the Fukushima Daiichi nuclear power plant to 3,355 times the legal limit.
In Hong Kong, a new independent committee formed to monitor the operation and safety of the Daya Bay nuclear plant in Shenzhen will stage an anti-nuclear protest on April 24.
The Daya Bay Public Monitoring Panel, spearheaded by Greenpeace and formed on Tuesday by 13 members including lawmakers and green activists, hopes the parade will raise public awareness of the danger the nuclear plant poses.
Greenpeace campaigner Prentice Koo Wai-muk said on a radio programme yesterday that the committee would monitor the safety performance of the plant by gathering information from the government and the plant.
As soon as the committee found out anything, the information would be immediately disclosed to the public, he said.
