Vancouver Sun: Scientists concerned dolphin species on west coast to be negatively impacted by Fukushima nuclear waste — Radiation levels to be increasing for years to come along coast — Canadian gov’t sampling for Iodine-129 in Pacific
Mission 2013-17 CCGS J P Tully (pdf), Sampling – Rick Nelson of Canada’s Department of Fisheries and Oceans, June 6 to 25, 2013: Cs-137 and I -129 Sampling […] large amounts of Cs-137 and other radionuclides [discharged] directly to the Western North Pacific ocean during the months following the [Fukushima] accident. The radioactivity plume was transported northeastward under the influence of the Kuroshio current and was expected to approach the Canadian coastline several years after the accident. A Canadian monitoring program was established to detect the arrival of Fukushima radioactivity in the water columns of the eastern North Pacific and the Arctic oceans. Water samples were collected at stations occupied on the “Line P” missions on the CCGS J P Tully in June of 2011, 2012 and this year 2013.
Vancouver Sun, April 12, 2014: Sometime in the next few weeks highly diluted, low-level radiation from the Japanese nuclear disaster is expected to reach West Coast shores […] Cesium levels will increase gradually over the next two or three years as the radioactive plume moves east toward the West Coast […] cesium-134 and cesium-137 don’t accumulate in fish and animals and become more concentrated up the food chain.*** […] There is some concern, however, on the impact it could have on orcas [killer whales, the largest of the dolphins] on the coast […] Initially in 2011, the amount of strontium-90 was a fiftieth that of cesium. But recently that changed to a one-to-one relationship […] While strontium isn’t being tested for in the Woods Hole crowdsourcing program, all the sea water samples will be stored in a warehouse […] to test them for strontium-90.
*** Many government researchers have published information directly contradicting the Vancouver Sun reporter’s claim:
- The French Radioprotection and Nuclear Safety Institute, April 20, 2011: “In the case of caesium, the concentration factors vary from 50 for molluscs and seaweed to 400 for fish. […] These accumulation phenomena are ample justification for the establishment of radiological monitoring programmes.”
- Even the banana-comparing Stony Brook University researchers got this part correct —Environmental Science & Technology, 2013: “137Cs and 134Cs in [Pacific blue fin tuna has] a dry wt concentration factor in PBFT muscle of 1000, and a wet wt concentration factor of 244, somewhat higher than the value of 100 calculated for generic marine fish.”
