North America’s West Coast getting record levels of Fukushima radiation

Record levels of Fukushima radiation detected off West Coast — Massive plume stretches for more than 1,000 miles — Reuters: Contamination is spreading off U.S. shores — Radioactive cesium reaches 11 Bq/m3 at multiple locationshttp://enenews.com/record-levels-fukushima-radiation-detected-west-coast-massive-plume-stretches-1000-miles-cesium-reaches-11-bqm3-multiple-locations-map?utm_source=feedburner&utm_medium=email&utm_campaign=Feed%3A+ENENews+%28Energy+News%29(MAP)

Woods Hole Oceanographic Institution, Dec 3, 2015 (emphasis added): Higher levels of Fukushima cesium detected offshore — Scientists monitoring the spread of radiation in the ocean from the Fukushima nuclear accident report finding an increased number of sites off the US West Coast showing signs of contamination from Fukushima. This includes thehighest detected level to date from a sample collected about 1,600 miles west of San Francisco. The level of radioactive cesium isotopes in the sample, 11 Becquerel’s per cubic meter… is 50 percent higher than other samples collected along the West Coast so far… Working with Japanese colleagues, [Ken Buesseler, a WHOI marine radiochemist] also continues to independently monitor the ongoing leaks from Fukushima Dai-ichi by collecting samples… During his most recent trip this October they collected samples of ocean water, marine organisms, seafloor sediment and groundwater along the coast near the reactors. Buesseler says the levels of radioactivity offFukushima remain elevated – some 10 to 100 times higher than off the US West Coast today, and he is working with colleagues at WHOI to try to determine how much radioactive material is still being released to the ocean each day.

Ken Buesseler, WHOI: “These new data are important for two reasons… 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… [F]inding values that are still elevated off Fukushima confirms that there is continued release from the plant.”

Statesman Journal, Dec 3, 2015: Higher levels of Fukushima radiation detected off West Coast— Higher levels of radiation from Japan’s 2011 Fukushima nuclear accident are showing up in the ocean off the west coast of North America, scientists from the Woods Hole Oceanographic Institution reported today. And an increased number of sampling sites are showing signs of contamination… This year, Buesseler has added about 110 new sample results to 135 already on the project’s web site. They include the highest detected level to date, from a sample collected about 1,600 miles west of San Francisco.

Reuters, Dec 3, 2015: Radiation from Japan nuclear disaster spreads off U.S. shores… andcontamination is increasing at previously identified sites… Tests of hundreds of samples of Pacific Ocean water confirmed that Japan’s Fukushima nuclear power plant continues to leak… The latest readings measured the highest radiation levels outside Japanese waters to date some 1,600 miles (2,574 km) west of San Francisco. The figures also confirm that the spread of radiation to North American waters is not isolated to a handful of locations, but can be detected along a stretch of more than 1,000 miles (1,600 km) offshore.
