"Levels of radioactive cesium from the 2011 Fukushima
Daiichi nuclear power plant accident detected off the U.S. west coast
pose no health risk, according to experts at the Woods Hole
Oceanographic Institution (WHOI).
The highest level reported to date (11 Bq/m3) was from a sample
collected about 1,600 miles west of San Francisco. Dr. Ken Buesseler, a
marine radiochemist and director of the WHOI Center for Marine and
Environmental Radioactivity, confirmed that this value is more than 500
times lower than U.S. government safety limits for drinking water. It is
also well below limits of concern for direct exposure while swimming,
boating, or any other recreational activity.
The recent data was released by Our Radioactive Ocean (ORO), a citizen
science sampling effort launched by Dr. Buesseler in 2014 to monitor
ocean waters for radionuclides from the Fukushima accident.
While ORO focuses on ocean chemistry, its Canadian partner InFORM
(Integrated Fukushima Ocean Radionuclide Monitoring) has been analyzing
fish samples in addition to seawater. To date, no fish have been found
to contain detectable levels of Fukushima-derived radionuclides. Both
ORO and InFORM demonstrate the benefits of partnering with citizen
scientists to address issues of public interest."
