Title: A Radioactive Nightmare

[...] Radioactive sea spray has been shown to blow hundreds of kilometers inland in tests conducted in the United Kingdom by British and European researchers.
[...] In the 2008 report “Sea to land transfer of radionuclides in Cumbria and North Wales,” the greatest average concentration of cesium-137 and plutonium-239 in soil at a depth of 0 to 15 centimeters was found 10 kilometers from the coast. The highest average amounts found at 15 to 30 centimeters deep were 5 kilometers away from the sea illustrating the unpredictability of radiation fallout.
A 62-page UK study released in December 2011 found that sea spray and marine aerosols created from bubbles forming and popping when the sea is choppy or waves break have increased concentrations of radioactive “actinides.”
Actinides are chemically alike radioactive metallic elements and include uranium and plutonium. One actinide infused the spray with an 812 times greater concentration of americium-241 than normal amounts of Am-241 in ambient seawater.
The report cited information that sea-spray-blown cesium 137 was found 200 kilometers from the discharge source in the New Hebrides islands in northern Scotland.
Another UK study found that the Irish Sea has a micro layer on top of it, perhaps only thousandths of a millimeter in thickness, that can become imbued with fine particulate material and its absorbed radiation.
These concentrations of plutonium and americium are four to five times their concentrations in ambient seawater. Plutonium concentrates by 26,000 times in floating algal blooms at sea, says the report. [...]
