Fukushima may turn out to be the world's worst nuclear disaster and may continue to release radiation for many years. Iodine-131 has been found in US drinking water as well as milk. With cesium-137 detected in American milk, in Montpelier, Vermont.

Ethan A. Huff of NaturalNews.com reports:
As far as the water supplies are concerned, it is important to note that the EPA is only testing for radioactive Iodine-131. There are no readings or data available for cesium, uranium, or plutonium -- all of which are being continuously emitted from Fukushima, as far as we know -- even though these elements are all much more deadly than Iodine-131. Even so, the following water supplies have thus far tested positive for Iodine-131, with the dates they were collected in parenthesis to the right:

Los Angeles, Calif. - 0.39 pCi/l (4/4/11)
Philadelphia (Baxter), Penn. - 0.46 pCi/l (4/4/11)
Philadelphia (Belmont), Penn. - 1.3 pCi/l (4/4/11)
Philadelphia (Queen), Penn. - 2.2 pCi/l (4/4/11)
Muscle Shoals, Al. - 0.16 pCi/l (3/31/11)
Niagara Falls, NY - 0.14 pCi/l (3/31/11)
Denver, Colo. - 0.17 pCi/l (3/31/11)
Detroit, Mich. - 0.28 pCi/l (3/31/11)
East Liverpool, Oh. - 0.42 pCi/l (3/30/11)
Trenton, NJ - 0.38 pCi/l (3/29/11)
Painesville, Oh. - 0.43 pCi/l (3/29/11)
Columbia, Penn. - 0.20 pCi/l (3/29/11)
Oak Ridge (4442), Tenn. - 0.28 pCi/l (3/29/11)
Oak Ridge (772), Tenn. - 0.20 pCi/l (3/29/11)
Oak Ridge (360), Tenn. - 0.18 pCi/l (3/29/11)
Helena, Mont. - 0.18 pCi/l (3/28/11)
Waretown, NJ - 0.38 pCi/l (3/28/11)
Cincinnati, Oh. - 0.13 pCi/l (3/28/11)
Pittsburgh, Penn. - 0.36 pCi/l (3/28/11)
Oak Ridge (371), Tenn. - 0.63 pCi/l (3/28/11)
Chattanooga, Tenn. - 1.6 pCi/l (3/28/11)
Boise, Id. - 0.2 pCi/l (3/28/11)
Richland, Wash. - 0.23 pCi/l (3/28/11)

Again, these figures do not include the other radioactive elements being spread by Fukushima, so there is no telling what the actual cumulative radiation levels really were in these samples. The figures were also taken two weeks before being reported. If current samples were taken at even more cities, and if the tests conducted included the many other radioactive elements besides Iodine-131, actual contamination levels would likely be frighteningly higher.

Radiation Filtration methods

There are different methods for filtering the isotopes mentioned above. The known effective methods for Iodine-131 and Iodine-133 is by Reverse Osmosis and GAC. Cesium-137 and Uranium are filtered by Reverse Osmosis. Since our reverse osmosis units include GAC filters and many other stages they are the most effective units on the market for this application. We have reverse osmosis systems designed for under your sink as well as a countertop option:
