Vietnam has detected a small amount of radioactive iodine I-131 in the air which poses no threat to human health, the Ministry of Science and Technology said Monday.
The ministry's Vietnam Atomic Energy Institute reported the same day that the fallout from Japan's quake-ravaged Fukushima Dai-ichi nuclear power plant had yet to reach Vietnam.
The radioactive fallout tended to approach Vietnam in the southeast direction, and part of it would probably be near Vietnam's southernmost Ca Mau Cape and the Phu Quoc Island, as well as Chinese Hainan Island Tuesday, the institute said.
Whether the fallout would spread into Vietnam over the next few days or not would depend on the Southeast Asia's weather conditions, it said.
However, even when it hits the country, it would still be very hard to detect their influence on the local background radiation, the institute said. Background radiation is radiation that is constantly present in the environment and is emitted from a variety of natural and artificial sources.
Also Monday, Satoru Toshimitsu, representative chief of Japan International Nuclear Power Development Company in Vietnam, said in a meeting with Deputy Minister of Science and Technology Le Dinh Tien that unless another tsunami or quake hits the Fukushima plant, Japan would be able to keep the consequences of its nuclear catastrophe to the minimum.
