Pacific Ocean radiation back near normal after Fukushima: study

A study has found that the seafloor and harbour near the Fukushima plant are still highly contaminated in the wake of the nuclear accident

Radiation levels across the Pacific Ocean are rapidly returning to normal five years after a meltdown at the Fukushima nuclear plant spewed gases and liquids into the sea, a study showed Monday. Continue reading Pacific Ocean radiation back near normal after Fukushima: study

Fukushima and the oceans: What do we know, five years on?

Published by PHYS.org
June 30, 2016

A major international review of the state of the oceans 5 years after the Fukushima disaster shows that radiation levels are decreasing rapidly except in the harbour area close to the nuclear plant itself where ongoing releases remain a concern. At the same time, the review’s lead author expresses concern at the lack of ongoing support to continue the radiation assessment, which he says is vital to understand how the risks are changing.

With Fukushima’s fifth anniversary approaching, we can probably start to relax about radioactive seafood

Fisherman from the “Kiyomaru” fishing boat pull in their net as they sail off the Iwaki town south of crippled Daiichi nuclear power plant, Fukushima prefecture September 20, 2013. Only a small part of the boat’s catch will be used to test for radioactive contamination in the waters near the Fukushima Daiichi nuclear facility, while the rest will be thrown back into the ocean.

March 11 will mark the five-year anniversary of the Fukushima Daiichi disaster, a series of nuclear meltdowns, triggered by a devastating earthquake-induced tsunami, that released massive amounts of radioactive material and resulted in the largest nuclear disaster since Chernobyl. Since then, the plant’s damaged drainage system has continued to leak radioactive water into the environment, and one of the biggest enduring public concerns has been the safety of fish caught in the area’s surrounding waters.

Summer 2014 Offshore Monitoring for Fukushima Contamination

By Jonathan Kellogg and Jay T. Cullen

Results from surface water samples collected in August 2014 during three oceanic research cruises are now available. These seawater samples were analyzed to characterize the distribution of Fukushima derived radionuclides 137-Cesium (137Cs half life ~30 years), and 134-Cesium (134Cs half life ~2 years). Based on the distribution of 134Cs, the Fukushima plume was not consistently present yet on the BC coast. It is likely that peak concentrations of radiocesium will be present offshore in the next year.
