Fukushima’s unsolved nuclear radiation problem

Fukushima Radiation Readings at Their Highest, Japan Is Contaminated Financial Feed,  by Chris Hartley on Apr 27, 2011  Robots sent to get Japan’s Fukushima Dai-Ichi reactor No. 1’s radiation readings reflected 1,120 millisierverts of radiation per hour, said the general manager of Tokyo Electric Power Co (Tepco) Junichi Matsumoto. The reading is 4 times higher than the yearly dose a nuclear worker is allowed to be exposed to……..Tepco said it is not possible to push through with the planned flooding of more water to reactor No. 1 to expedite its emergency cooling efforts. Kyoto University nuclear engineering professor Hironobu Unesaki said Tepco must figure out the high radiation’s source. If it’s from contaminated water leaking from inside the reactor, Tepco’s so-called water tomb may be jeopardized because flooding the containment vessel will result in more radiation in the building, added the professor. The explosion at the plant damaged reactors 1, 2, and 3’s cores and reactor 4’s fuel rods. Tepco has used several emergency measures to cool the units, such as pouring millions of liters of water.
