Record-high radiation detected at Fukushima report by Australian Scientist

The company that owns Japan's stricken Fukushima nuclear power plant says it has detected record-high radiation on site.
Almost five months after Japan's government announced a nuclear emergency, the company which owns the Fukushima nuclear plant, Tokyo Electric Power Company (TEPCO), says radiation levels have reached at least 10 sieverts per hour near Fukushima's No. 1 and No. 2 reactors.
The radiation levels are more than double the previous record high that was reached in early June.
One nuclear expert predicts the clean-up from the March 11 earthquake and tsunami will be even more difficult, but there is speculation that the reading could be an aberration.
Peter Burns, former chief executive officer of the Australian Radiation Protection and Nuclear Safety Agency, says given the scale of the Fukushima emergency, the high reading is to be expected.
"The levels reported of 10 sieverts per hour are very high levels and it's going to be very difficult to manage workers going into those areas and doing operations," he said.
"To put the 10 sieverts into context, that 10 sieverts is actually a lethal dose of radiation. So you can't afford to be exposed for more than a few minutes at those levels.
"It means you're directly exposed to fuel rods in the reactors or the spent fuel ponds very closely and while it's possible to get to those levels it means there is very little shielding going on there."
In the week after the quake and tsunami, which triggered an explosion at the facility and a nuclear meltdown, military helicopters water bombed the power plant to try stop fuel rods and containment pools being exposed to the air.
