About This Video
Seven years ago, a 9.0 magnitude earthquake followed by a massive tsunami led to three nuclear reactor meltdowns and a series of explosions at the Fukushima Daiichi plant in Japan. More than 90 per cent of the resulting radiation went into the Pacific Ocean. Years later, that radiation slowly made its way to Canadian shores. Steve Paikin welcomes the chemical oceanographer tracking the disaster’s ocean contamination to learn the effects of the radiation.

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.

The InFORM Team Remembers Dr. Jack Cornett

Dr. Jack CornettThis week InFORM lost a friend, a colleague, and a leader in his field, Dr. Jack Cornett. Jack was an integral member of the InFORM team since he was involved in the analyses of both our citizen science and biological sampling efforts and was using new mass spectrometry techniques to measure trace concentrations of Fukushima derived isotopes in seawater and freshwater. This work was conducted by his extensive lab group, but as anyone who knew Jack knows, he was personally involved and invested in all aspects of the lab operations on a near daily basis.

Originally published by Eos, a periodical of the American Geophysical Union

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

by WHOI Media Relations
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.
