Ken Buesseler, the marine radiochemist that discovered these high levels of radiation plans to present his findings at the American Geophysical Union Conference in San Fransisco next week.
“These new data are important for two reasons,” Buesseler, one of the first scientists to track Fukushima radiation, said in a press release. “First, despite the fact that the levels of contamination off our shores remain well below government-established safety limits for human health or to marine life, the changing values underscore the need to more closely monitor contamination levels across the Pacific.”
“Second, these long-lived radioisotopes will serve as markers for years to come for scientists studying ocean currents and mixing in coastal and offshore waters.”
Buesseler, working with Japanese scientists, also continues to monitor the continuing leakage from the Fukushima plant, which includes collecting water samples from as close as a half mile away and sampling marine organisms, sediment and groundwater along the coast. The radiation levels there, while decreased, remain 10 to 100 times higher than those off the U.S. coast.
Perhaps the reason the government isn’t concerned with any of this is because the EPA keeps turning off their detectors. It would seem that shutting them off is a cheaper alternative to getting them fixed. Meanwhile the American coast continues to get battered with radiation. The Tokyo Electric Power Company is working to keep the groundwater from flowing through the wrecked plant, but eventually the entire facility has to be dismantled and hauled away.
