Update on radiation from Japan

Update: Yet again Facebook censored our article, particularly in U.S. by deleting comments, wall posts and even forcing its user to enter security text code prior to posting the article link on their wall.

Thanks to the jet stream air currents that flow across the Pacific Ocean, the U.S. is receiving a steady flow of radiation from Fukushima Daichi. And while many scientists say that the levels of contamination in food pose no significant threat to health, scientists are unable to establish any actual safe limit for radiation in food. Detection of radioactive iodine 131, which degrades rapidly, in California milk samples shows that the fallout from Japan is reaching the U.S. quickly."

"Milk, fruits and vegetables show trace amounts of radioactive isotopes from the Fukushima Daichi power plants, and the media appears to be paying scant attention, if any attention at all. It is as if the problem only involves Japan, not the vast Pacific Ocean, into which highly radioactive water has poured by the dozens of tons, and not into air currents and rainwater that carry radiation to U.S. soil and to the rest of the world."

"Radiation tests conducted since the nuclear disaster in Japan have detected radioactive iodine and cesium in milk and vegetables produced in California. According to tests conducted by scientists at the UC Berkeley Department of Nuclear Engineering, milk from grass fed cows in Sonoma County was contaminated with cesium 137 and cesium 134. Milk sold in Arizona, Arkansas, Hawaii, Vermont and Washington has also tested positive for radiation since the accident."

"Additionally, drinking water tested in some U.S. municipalities also shows radioactive contamination. Is the fallout from Fukushima Daichi falling on us? Yes, it is."

“Children are much more susceptible to the effects of radiation and stand a much greater chance of developing cancer than adults,” states Andrew Kanter, MD, president of PSR’s board. “So it is particularly dangerous when they consume radioactive food or water.” - Fox News

Radioactive Milk: Strontium Found in Hilo, Hawaii Milk

Last month we had also reported how a radioactive isotope of strontium had already been detected in American milk sample from Hilo, Hawaii. EPA found 1.4 picoCuries per liter of strontium-89 in a milk sample collected in Hilo on April 4, 2011

Although the EPA tests milk, the FDA regulates it, and the FDA’s Derived Intervention Level—the standard observed for food—is 4,400 pCi/L for strontium-90. I’m working to confirm whether FDA has a separate DIL for Sr-89.

The EPA’s Maximum Contamination Level for Sr-89 in drinking water is 20 pCi/L. (For more on the difference between EPA and FDA standards, see “Why Does FDA Tolerate More Radiation Than EPA?“)

The two man-made isotopes of strontium—Sr-89 and Sr-90—are among the most dangerous products of nuclear fission to human and animal health. Both are “bone-seekers,” chemically similar to calcium, that collect in bone and marrow, where they are known to cause cancer. They are particularly dangerous to the growing bones of fetuses and children.

The half-life of Sr-89 is 50.5 days, and Sr-89 is sometimes used as a cancer pain treatment under the commercial name Metastron, because it collects in and destroys the fast-growing cells of bone cancer. EPA considers Sr-90, meanwhile, “the most important radioactive isotope in the environment” because of its health impacts and a longer half-life of 29 years.
