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
3/ In 1967 levels of 137-Cs in Pacific seawater were ~20 times higher than peak levels we saw off North America post #Fukushima. Salmon in the mid-1960s were much more contaminated then levels we see in fish 2014-2018 returning to North American rivers to spawn
4/ Average levels in salmon have not changed given the modest increase in seawater 137-Cs after #Fukushima here and we do not see any indication of biomagnification or marked bioaccumulation in the salmon
5/ Average levels of 0.2 Bq/kg in our fish are 5000 times lower than Health Canada's maximum allowable levels of 1000 Bq/kg. Consumption of these fish do not represent a health risk to the public and the risk has not changed since 2011
6/ This monitoring project and the collection of this important data was supported by @MEOPAR_NCE and all of the data and interpretation of peer reviewed literature can be found at the project website fukushimainform.ca
7/ Please share this information and if you have friends interested in how contamination from #Fukushima is being dispersed in the #Pacific please let them know I am happy to answer questions
