[While radiation levels in the surrounding areas have come down, deadly radiation inside the buildings that housed the reactors is still preventing cleanup crews to even take a look at the situation. Meanwhile 960,000 tons of contaminated water used for cooling the fuel rods has accumulated in 1000 tanks and scientists are unable to get rid of its toxic load.]

A single dose of 10 sieverts is enough to kill a human within weeks. This robot was one in a series of devices designed by top firms to go into the basements of reactors where an estimated 600 tons of molten radioactive fuel has burned through the massive concrete casings and lies smoldering. The tsunami of March 11, 2011 was one of the deadliest ever and it knocked off the cooling systems of an ill-prepared nuclear plant complex at Fukushima. This led to a runaway heating up of highly radioactive fuel rods, explosions of radioactive gases and contamination of groundwater. Some 160,000 people living in the vicinity of the complex were evacuated and most of them remain in camps away from the disaster site. Latest Comment Grim and chilling reminder of how dangerous it is to use nuclear technology for fuel. Unfortunately, as we exhaust coal and fossil fuels, we will be forced to go for nuclear technology for our never...

One tricky issue has been to control contamination of groundwater which naturally flows under the stricken plant and out to sea. A frozen wall has been built to prevent contamination and Masuda said that it had minimised the risk. The removal of radioactive Tritium, an isotope of hydrogen, from the stored water used to cool the fuel remains an intractable technical issue. -- Peace Is Doable -- You received this message because you are subscribed to the Google Groups "Green Youth Movement" group.
