TEPCO has revised the readings on the radioactivity levels at the Fukushima No. 1 nuclear plant well to 5 million becquerels of strontium per liter – both a record, and nearly five times higher than the original reading of 900,000 becquerels per liter. Strontium-90 is a radioactive isotope of strontium produced by nuclear fission with a half-life of 28.8 years. The legal standard for strontium emissions... 

The operator of Japan’s crippled Fukushima Daiichi atomic plant plans to start cleaning underground tunnels believed to be part of the sources of radioactive materials poisoning the groundwater in the area. The Tokyo Electric Power Company (TEPCO) will first block the flow of tainted water between the damaged buildings and the tunnels. Workers will begin burying pipes in the ground to carry refrigerants... 

Radiation readings from the EnviroReporter have revealed high levels of HOT particles in Michigan, possibly from the Fukushima nuclear disaster. Radiation levels after a storm in the area read 561% over normal background levels. Then, after a second storm, the levels were even higher, 6.5 times higher than normal accepted levels to be exact. Michael Collins, the founder of EnviroReporter recently... 

Strontium 90 was measured in Yokohama, Kouhokuku. In the simplest put, it’s over. The amount was 195 Bq/kg, detected by a university staff teaching engineering, so the measurement is trustworthy. It has nothing to do with the historical world-wide nuclear test, because it was measured on the roof of and apartment, which was built only 5 years ago. Now the test result was sent to Yokohama city government. Yokohama...
