As a team from the Link Removed - Invalid URL visits Tokyo Electric Power Co.’s crippled nuclear plant today, academics warn the company has failed to disclose the scale of radiation leaks and faces a “massive problem” with contaminated water. The utility known as Tepco has been pumping...

New evidence suggests that nuclear chain reactions at the Fukushima power plant didn't end when the generators were initially shut down, following the March 11 earthquake. Technology Review explains why Tetsuo Matsui, a researcher at the University of Tokyo, thinks conditions inside two of...

We have at least three sources who believe that there is evidence of recriticality at Fukushima. What's troubling is that it is uncontrolled criticality. For those who don't know, this means the fission process is starting and stopping at random. Blue flashes of light have been witnessed at...

With measurements of iodine 131 and the much worse cesium 134 isotopes detected at 7.5 and two million times past their “regulated levels” and contaminated water pouring into the Pacific Ocean, this was inevitable: the fish are contaminated too. The Bulletin of the Atomic Scientists reports that...

Link RemovedWorkers in Japan are still struggling to limit environmental contamination at the Fukushima plant. The latest problem has been a break that is allowing heavily contaminated water flow directly into the ocean, a leak that has continued despite two attempts to plug it. Meanwhile...

The soil samples should normally be 100 Bequrels. The Japanese governments safety standard is 500 Bequrels. If the soil is contaminated with 20000000 Bequrels of radio active isotopes this is 19999500 Above the government safety standard. If as NHK is reporting this is the number detected, the...

On March 23, Dr. Link Removed - Invalid URL a Research Scientist at the Monterey Institute of International Studies saw a report by Kyodo news agency that caught his eye. It reported that Tokyo Electric Power Company (TEPCO) had observed a neutron beam about 1.5 km away from the plant. Bursts of...

RADIATION levels that can prove fatal were detected outside reactor buildings at Japan’s Fukushima No.1 plant for the first time, complicating efforts to contain the worst disaster since Chernobyl in 1986. Water in an underground trench outside the No.2 reactor had levels exceeding one sievert...
