High radiation still detected at Fukushima plant 7 years after disaster

The operator of the crippled Fukushima Daiichi nuclear power plant has released the results of its latest probe of the site. A remote-controlled inspection of the Unit 2 reactor containment vessel last month detected a maximum of 8 sieverts per hour of radiation. Experts say exposure to such radiation for about an hour would be fatal. The finding shows that nearly 7 years after the meltdowns, radiation levels remain so high that they present a major challenge to decommissioning work.
