Scientists fear that radiation leaked from the Fukushima Number One Nuclear Power Plant will most likely impact the northeast region of Japan, although the government insists the levels are low.

They worry the resulting cloud will drift in the wind, affecting neighboring areas. Meteorological officials say a westerly wind will dominate the zone around the facility throughout Sunday.

Its direction will later change, and blow toward the north. Cities located north of the site will be affected. China is not predicted to be impacted by the radiation in the next three days.

Meanwhile, the Fukushima Number Two Nuclear Power Plant has also lost cooling ability. Operators are releasing steam from reactors to reduce pressure. Authorities have ordered an evacuation radius of 10 kilometers.
