The Vietnam Atomic Energy Commission Monday ordered related agencies to measure radioactive levels in the atmosphere following blasts at a Japanese quake-hit nuclear power plant, VnExpress reported.
Vuong Huu Tan, deputy head of the agency under the Ministry of Sciences and Technology, said the Japanese nuclear accident was classified at level four, so it was likely to affect nearby areas.
So far tests around stations managed by the Da Lat Institute of Nuclear Research and the Hanoi Institute for Nuclear Science and Technique have shown no abnormality, he said.
Vietnam is cooperating with Japan and other countries to gather information for carrying out studies on the accident, Tan said.
The Fukushima Daiichi nuclear reactor complex in Japan's Fukushima prefecture Tuesday experienced its third explosion after a fire since it was damaged in last Friday's massive earthquake and tsunami, Reuters reported.
Japanese authorities have warned of radiation leaks that could worsen in the days to come.
Meanwhile, Hanoi has announced that it will implement a response plan for earthquakes, including requirements for buildings to be quake-proofed.
Making people more aware and training them in responding to quakes and other disasters is part of the plan being considered by the Hanoi People's Committee.
The death toll from the earthquake and tsunami in Japan has climbed to 2,400 as of Tuesday, AP quoted local police as saying, adding that officials have previously said at least 10,000 people may have died in Miyagi prefecture alone.
