No Fukushima Contamination in Alaskan Fish – 2017 Update

AlaskaDEC

No Fukushima contamination has been found in any of 12 fish sampled and tested by the Alaska Department of Environmental Conservation (DEC) in 2017. Sampled between March and July 2017, the Pollock (Gadus chalcogrammus), Pacific Cod (Gadus macrocephalus), Halibut (Hippoglossus stenolepis), Herring (Clupea pallasii), and salmon (Sockeye (Oncorhynchus nerka), Chinook (O. tshawytscha), and Chum (O. keta)) were sampled from waters off the the Southeast panhandle to the Bering Sea.

One salmon found with Fukushima Contamination in 2016 After Extended Measurement

Extended testing of select 2016 salmon samples has identified the Fukushima-fingerprint isotope in one sample re-measured earlier this year.  The maximum level of contamination observed in a sample  (134Cs: 0.07 Bq kg-1137Cs: 0.51 Bq kg-1) is over 1,700 times lower than the Health Canada Action Level (1,000 Bq kg-1) and is not known to be a health risk for either humans or the environment.

Laboratories outside Japan have validated the results. Marine radioactivity levels from the nuclear disaster have fallen, but questions remain years after the meltdown. Continue reading IAEA Affirms Japan’s Fukushima-Related Radioactivity Monitoring

Scientists Find New Source of Radioactivity from Fukushima Disaster

Published 2 October 2017

Scientists have found a previously unsuspected place where radioactive material from the Fukushima Dai-ichi nuclear power plant disaster has accumulated—in sands and brackish groundwater beneath beaches up to 60 miles away. The sands took up and retained radioactive cesium originating from the disaster in 2011 and have been slowly releasing it back to the ocean.
