The earthquake-crippled Fukushima No. 1 nuclear plant suffered a dangerous radiation leak Tuesday in the wake of two new explosions and a fire as officials on site scrambled to avert a meltdown.

The figure was 100 millisieverts per hour near the No. 4 reactor and 30 millisieverts per hour between the No. 2 and No. 3 reactors.
