Hours after the evacuation order for those within a two-mile range of the plant in northeastern Japan, the government announced that the plant will release slightly radioactive vapor from the unit to lower the pressure in an effort to protect it from a possible meltdown.
Chief Cabinet Secretary Yukio Edano said the amount of radioactive element in the vapor would be "very small" and would not affect the environment or human health. "With evacuation in place and the ocean-bound wind, we can ensure the safety," he said at a televised news conference.
