Spiking radiation levels at Fukushima......
A single dose of one sievert is enough to cause radiation sickness and nausea
5 sieverts would kill half those exposed to it within a month
a single dose of 10 sieverts would prove fatal within weeks.
The recent reading, described by some experts as “unimaginable”, is far higher than the previous record of 73 sieverts an hour
Tokyo Electric Power (Tepco), said atmospheric readings as high as 530 sieverts (WOW!!!) an hour had been recorded inside the containment vessel of reactor No 2
Tepco also said image analysis had revealed a hole in metal grating beneath the same reactor’s pressure vessel. The one-metre-wide hole was probably created by nuclear fuel that melted and then penetrated the vessel
A remote-controlled robot that Tepco intends to send into the No 2 reactor’s containment vessel is designed to withstand exposure to a total of 1,000 sieverts, meaning it would survive for less than two hours before malfunctioning.
Tepco and its network of partner companies at Fukushima Daiichi have yet to identify the location and condition of melted fuel in the three most seriously damaged reactors. (IT HAS ONLY BEEN 6 YEARS.......WHAT IS THE RUSH) Removing it safely represents a challenge unprecedented in the history of nuclear power
