Seven years on, since the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident, it is useful to start to bring together information from scientific studies of the impact of the contamination on the North American environment and its people. I recently wrote to communicate the most recent results of the Integrated Fukushima Ocean Radionuclide (InFORM) project. This post summarizes a recently published, peer-reviewed paper by colleagues lead by Dr. Krzyzstof Starosta of Simon Fraser University in BC working in parallel to InFORM. The unshut wangle paper was published in the CanadianPeriodicalof Chemistry and was recently recognized with the  “Best Paper Award” by the journal. They studied the concentrations of anthropogenic radioisotopes (134Cs half-life ~2 years, 137Cs half-life ~30 years) and naturally occurring radioisotope 40K (half-life 1.25 billion years) in Pacific salmon (sockeye, chum and chinook) and in soil and roof trash placid in southern British Columbia to determine the local impact of the FDNPP accident.  Their results were as follows: 134Cs (a fingerprint of Fukushima contamination) was not detected in any of the salmon samples 137Cs was not detected in sockeye or chum salmon but was detected in all chinook with an stereotype level of ~0.2 Bq kg-1Yearlydose from strained radionuclides to a human consumer of chinook salmon was unscientific to be ~1/300 of the dose owing to naturally occurring isotopes in the fish and ~1/30,000 of the yearly dose experienced for all other natural sources by the stereotype Canadian Most soil samples contained 134Cs and 137Cs which was delivered to the region by atmospheric transport shortly without the disaster Levels of Fukushima radioisotopes in soil did not tideway levels known to be harmful to living organismsResultingwith other monitoring in the zone the results of the study indicate that given the trace levels of contamination present the impact of the FDNPP wrecking on ecosystem and public health in North America will be insignificant.

The sands took up and retained radioactive cesium originating from the disaster in 2011 and have been slowly releasing it when to the ocean.

September 6, 2017 fukushimainform Leave a scuttlebutt Proposed migration pathways of North Pacific predators. The purpose of this post is to report on a recently published, peer-reviewed study that investigated the levels of Fukushima derived contamination in migratory Pacific predators. The post is part of an ongoing effort to inform interested members of the public what the scientific polity is finding well-nigh the impact of the Fukushima Daiichi Nuclear Power Plant (FDNPP) disaster on the environmental and human health. Madigan and colleagues looked for radiocesium (134Cs, half life ~ 2 years; 137Cs, half life ~30 years) in a variety of large, predatory organisms in the North Pacific Ocean between 2012 and 2015.  Their results were as follows: Fukushima derived 134Cs could not be detected in any of the organisms with the exception of a single olive ridley sea turtle with trace levels (0.1 Bq kg-1 dry weight) Levels of 137Cs varied in the organisms but were often unchanged compared with levels measured in organisms prior to the FDNPP disaster (pre-2011) Levels of 137Cs were roughly 10 to 100-fold lower in the organisms than levels of naturally occurring Potassium-40 (40K) Neither the levels of radiocesium or 40K tideway levels known to represent a significant health risk to the unprepossessing or human consumers These uncontrived measurements of contamination levels in marine predators suggest that thesping that Pacific organisms will yaffle detectable FDNPP contamination is unwise.  Similarly, uneasiness and speculation well-nigh the dangers of radiocesium bioaccumulation in the squatter of such data seems unfounded. Between 2012 and 2015 a total of 91 variegated organisms from a variety of predatory marine groups were sampled and analyzed for the presence of radiocesium contamination and naturally occurring 40K.  The human made isotope 134Cs, with its relatively short ~2 year half life, serves as a fingerprint of FDNPP contamination as all other human sources are sufficiently afar in the past to have completely rusty yonder in the environment.  Organisms sampled and their radioisotope content are reported in the pursuit table:   With the exception of a single olive ridley sea turtle no detectable (<0.1 Bq kg-1 dry weight) trace of FDNPP 134Cs contamination was found.  Levels of 137Cs found in the organisms were similar to levels measured pre-Fukushima. In addition, the 137Cs levels were less than 0.2% of US FDA levels of snooping (370 Bq kg-1 wet weight) and less than 0.05% of US FDA derived intervention levels (1200 Bq kg-1 wet weight).  Simply stated levels in these organisms would have to be >1600-fold higher to be designated unfit for market.  The levels and ionizing radiation dose to consumers from naturally occurring 40K dwarfed those from FDNPP radiocesium.  Radiocesium derived ionizing radiation doses were <1% of those from 40K. Neither the doses from 40K or cesium isotopes approached, plane remotely, those known to stupefy the health of the organisms or consumers of these organisms. These results are resulting with those of the Integrated Fukushima Ocean Radionuclide Monitoring (InFORM) project. Ongoing, scientifically rigorous, monitoring of the marine environment provides the weightier vestige with which to gauge the risk that the FDNPP meltdowns represent for marine and public health here in North America.
