Tokyo Electric Power Company says radiation levels around the compound at its Fukushima Daiichi nuclear plant are on the decline since water-spraying began in earnest on Saturday afternoon.

The company told reporters that the radiation level at the plant's headquarters building, located some 500 meters northeast of the No. 3 reactor, dropped to 2,625 microsieverts per hour at 8:30 on Sunday morning.

The reading shows a drop of more than 800 microsieverts from 18 hours ago--about the time the water-spraying at the No.3 reactor began.
