Police from Tokyo have begun using their riot control water trucks to spray water on reactor 4, Fukushima Daiichi.

The JSDF has resumed dropping water on reactor 3, despite high radiation levels.  Officials say the overheating situation has become so bad that they had no choice but to have helicopter crews be exposed to high levels of radiation.

Officials say workers on the ground, and helicopter crews are wearing protective clothing.  A lead plate has been attached to the bottom of the CH-47 copter. Officials say reactor 3 requires at least hundreds of dumps of water from helicopters.  This is a logistical problem, regardless of the radiation, which is why they have brought in police, and fire, water trucks.  Another 11 water trucks are heading to the plant.
