The incident — newly chance on leaks of radioactive water — was first relegate as a stage one incident on the International Nuclear and Radiological Event Scale ( INES ) , which advert to an “ anomaly . ” Now , report the BBC , that ’s set to be upgraded to even out three — which make it numerate as a “ serious incident . ” That might not sound a immense jump , until you realize that the inclemency of an effect is about 10 times greater for each growth in storey . So , just 100 times bad than expected , then .
In fact , on the seven - point scale , a three counts as the most serious incident . The rest of the weighing machine , four to seven , is reserved for accidents , with only two events ever score a seven : the initial meltdowns at Chernobyl and Fukushima .
The current problems at Fukushima is a solution of radiation levels detected in puddle surrounding the site . Over 300 tonnes of radioactive pee surround the abandoned plant , and one puddle of polluted body of water was found to be pass off 100 millisieverts an hour of actinotherapy . That ’s serious , asMasayuki Ono explained to Reuters :
“ One hundred millisieverts per hour is equivalent to the boundary for accumulated pic over five age for nuclear worker ; 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 . ”
Ground crews are now attempt to stem flows from leaking armoured combat vehicle with sandbags , and draw up the puddles that have been forming . It ’s slow study , though , with doer being rotated regularly to avoid overexposure to radiation — which entail stack of the water has already disappeared into the ground . [ BBC ]
