Japan: Nuclear Plant Workers In Hospital
Three workers at the Fukushima Daiichi nuclear plant have been taken ill after being exposed to radiation, Japan’s nuclear safety agency says.
More than 20 people have been injured since the plant was damaged
Two of the workers needed hospital treatment.
Fumio Matsuda, a spokesman for the agency, said they had been exposed to radioactive elements while laying electrical cables at Unit 1 of the plant.
Two were exposed to radioactive elements on the skin of their feet.
They suffered exposure to radiation ranging from 170 to 180 milli-sieverts. An exposure of 100 milli-sieverts per year is considered the lowest level at which any increase in cancer risk is evident.
About two dozen people have been injured since the plant began leaking radiation after suffering tsunami damage on March 11.
Technicians have now restored power to the reactor number one control room.
The progress means workers can now use two crucial control rooms – at reactors 1 and 3 – which they were earlier forced to abandon after a series of explosions and amid strong radiation and in darkness.
The quake and tsunami cut electricity to the plant and knocked out backup systems, causing the cooling systems to fail.
This left the fuel rods inside to heat up and evaporate water, threatening a full meltdown.
Fire engines have hosed down the reactors and topped up spent fuel rod pools to prevent the uranium and plutonium from being exposed to the air – steps intended to stop a major disaster, but also creating radioactive steam.
Reconnecting the reactor control rooms was seen as a key step as workers hope to restart the original cooling systems.
:: Many shops in Tokyo have run out of bottled water after radiation from the damaged nuclear plant made tap water unsafe for babies.
In Chiba province, next to the capital Tokyo, officials have detected radioactive substances in its water purification system in amounts above what is considered safe for infants.
