FUKUSHIMA, Japan (My TV20 News at 10) --- People were tested for radiation exposure today at screening centers in Fukushima, Japan.
Japan's cabinet secretary warned a partial meltdown in unit three at a power plant in Fukushima is "highly possible."
Unit three is one of the three working reactors at the plant that lost cooling functions after the earthquake and tsunami.
An explosion destroyed the walls of unit one yesterday as the plant's operator tried to keep it from overheating.
Around 170,000 people who live within 12 miles of the plant have been ordered to leave.
Operators released slightly radioactive air from unit three today and began pumping sea water into it in an effort to prevent a meltdown.
