Fukushima Fallout Reaches U.S.A.
April 1, 2011
Three of the six nuclear reactors at Fukushima Daiichi nuclear plant have partially melted down and highly toxic plutonium is seeping into the soil outside. Plutonium is less volatile than other radioactive elements like iodine or cesium, but it’s also more deadly. According to Businessweek, “When plutonium decays, it emits what is known as an alpha particle, a relatively big particle that carries a lot of energy. When an alpha particle hits body tissue, it can damage the DNA of a cell and lead to a cancer-causing mutation.” If plutonium leaches into groundwater or pristine aquifers, the threat to public health and the environment will be extreme. This is an excerpt from an article in the Guardian:
“The radioactive core in a reactor at the crippled Fukushima nuclear power plant appears to have melted through the bottom of its containment vessel and on to a concrete floor, experts say, raising fears of a major release of radiation at the site. The warning follows an analysis by a leading US expert of radiation levels at the plant….
Richard Lahey, who was head of safety research for boiling-water reactors at General Electric when the company installed the units at Fukushima, told the Guardian workers at the site appeared to have “lost the race” to save the reactor…” (“Japan may have lost race to save nuclear reactor”, The Guardian)
It also appears that underground tunnels at the facility have been flooded with radioactive water that contains high-concentrations of caesium-137. A considerable amount of the water has made its way to the sea where samples show the levels of contamination steadily rising. This is from the Wall Street Journal:
“Levels of radiation in the ocean next to the Fukushima Daiichi nuclear power plant have surged to record highs, the government said Wednesday, as operators try to deal with large amounts of radioactive water—the unwanted byproduct of operations to cool the reactors.
The Nuclear and Industrial Safety Agency said water taken Tuesday afternoon from the monitoring location for the troubled reactors Nos. 1 to 4 had 3,355 times the permitted concentration of iodine-131. That is the highest yet recorded at the sampling location, which is 330 meters south of the reactors’ discharge outlet.” (“Seawater Radiation Level Soars Near Plant”, Wall Street Journal) All fishing has been banned in the vicinity as the toxins pose a danger to human health.
