The operator of Japan’s Fukushima nuclear power plant says that seawater radioactivity fifteen kilometres offshore has risen significantly. Plant operator TEPCO reports it is 600 times the maximum allowed by law.
The company has released a new video of the inside of reactor number one. A US-made robot recorded the images on April 29. Experts confirmed that electricity cables were safe and there were no water leaks, but said radiation levels were higher than expected.
