Thread: 1/ There will be a lot of talk in the coming weeks about the Japanese Government planning to dispose of radioactive wastewater at the #Fukushima Daiichi nuclear plant site in the ocean. Much of the focus will be on a form of radioactive hydrogen called tritium 2/ Tritium is difficult to remove from wastewater at the site because it is largely present in the form of the water molecule itself and therefore resists traditional methods used to clean/extract contaminants

Thread 1/ #Typhoon Hagibis made landfall in #Japan and has caused widespread flooding with human lives lost. Spare a thought for those in Japan who need help at present. #Fukushima Daiichi. But some are using this storm to promote scientific misinformation 2/ I am seeing posts that link the #radioactive contamination/decay heat from #Fukushima Daiichi & the development of tropical cyclones like #Hagibis and going so far as to say the human caused global warming is not like to #CO2 but nuclear fallout/contamination

Thread 1/ Some recent results of @FukushimaInFORM monitoring project which is tracking contamination from #Fukushima in Canada and the Northeast Pacific Ocean off North America fukushimainform.ca 2/ This figure compares levels of Cesium-137 (half life ~30 years) measured in salmon collected from the Northeast Pacific post #Fukushima with levels measured in 1967 just after atmospheric nuclear weapons testing was halted by the introduction of the Comprehensive Test Ban

Thread: 1/ Team members of @FukushimaInFORM have been monitoring the impacts of the #Fukushima disaster on marine and public health in Canada since the meltdowns at the Daiichi nuclear power plant in 2011 2/ We have a new paper in press summarizing our work looking for #Fukushima contamination in almost 300 #Pacific salmon collected near to North America in 2013-2016 returning to the rivers shown below

1/n Thread: Routinely people write or tweet at me that #Fukushima is still leaking to the ocean and therefore contamination levels in #Pacific seawater and marine organisms must be increasing. This is just not so. 2/n My reply is that rates of releases now are so low compared to March-April 2011 that one can barely detect that #Fukushima is leaking at all into the ocean even near to the Japanese coast. Colleague Michio Aoyama has just published a peer-reviewed paper showing just that
