The latest surge in radiation at Fukushima nuclear plant may suggest not only additional water leaks at the site, but could also mean fission is occurring outside the crippled reactor, explains Chris Busby from the European Committee on Radiation Risk.
The increase in radiation reading is too significant to be blamed on random water leaks, believes Busby.
RT: Just how serious is the situation now in Japan?
Chris Busby: I think this is an indication that it has actually deteriorated significantly, very suddenly in the last week. What they are not saying and what is the missing piece of evidence here is that radiation suddenly cannot increase unless something happens and that something cannot be leakage from a tank, because gamma radiation goes straight through a tank. The tank has got very thin metal walls. These walls will only attenuate gamma radiation by 5 per cent, even when it is 1 cm thick.
Although they may think this is a leak from the tank, and there may well be leaks from the tank, this sudden increase of 1.8 Sieverts per hour is an enormously big doze that can probably kill somebody in 2 to 4 hours.
Today there was another leak found at 1.7 Sieverts per hour in more or less the same place. This huge radiation increase, in my mind means something going on outside the tanks, some radioactive fission is occurring, like an open air reactor, if you like, under the ground.
RT: What impact will this have on the clean-up operation and those who are involved in that operation?
CB: First of all it is clearly out of control and secondly no one can go anywhere near it. Nobody can go in to measure where these leaks are or do anything about them, because anybody who is to approach that sort of area would be dead quite quickly. They would be seriously harmed.
