Japan again faces radiation problems

A puddle of the contaminated water was emitting 100 millisieverts an hour of radiation, Kyodo news agency said earlier this week.

Masayuki Ono, general manager of Tepco, told Reuters news agency: “One hundred millisieverts per hour is equivalent to the limit for accumulated exposure over five years for nuclear workers; so it can be said that we found a radiation level strong enough to give someone a five-year dose of radiation within one hour.”

Japan has declared a level-three “serious incident” situation. Two years ago, at the height of the plant’s meltdown, Fukushima was a level seven. This is the highest warning issued since then
Tokyo Electric Power Co (Tepco) said it did not know how the water leaked out or where it had leaked to, but it believed that the spillage had not flowed into the Pacific ocean.
On top of this latest emergency, Tepco announced earlier this month that contaminated groundwater continues to be a problem.

The environment ministry recently announcement that 300 tonnes of contaminated groundwater from Fukushima Daiichi is still seeping over or around barriers into the Pacific every day, more than two years after it was struck by a tsunami in March 2011. Government officials said they suspected the leaks had started soon after the accident, which resulted in a nuclear meltdown.
