Radiation risk from Fukushima disaster drifts across Pacific

Radiation risk from Fukushima disaster drifts across Pacific

A study based on recent data has pointed towards the fact that radiation from the Fukushima nuclear power plant disaster has now drifted across the Pacific. With this news, there are fears that this radiation could be spread along the British Columbia coast and it might prove to be very harmful for salmon and other marine life.

The samples that are generated by citizen scientists have enabled a much more comprehensive study that was done by Fisheries and Oceans Canada. This study indicated towards the levels of radiation. These are so low that they pose almost zero risk to human or ecosystem health. The researchers also stated that there should be no fears associated with the consumption of salmon as it is safe to eat and also the ocean is clean enough to swim in.

These results have been generated by the researchers who have been monitoring the arrival of Fukushima contamination plume in the British Columbia waters. This study was led by John Smith, an oceanographer at the federal government's Bedford Institute of Oceanography, which confirms radiation from Fukushima has reached the continental waters of North America.

This detail of this study has been published this week by the Proceedings of the National Academy of Sciences.

This radiation from the Fukushima disaster occurred during an earthquake-triggered tsunami in Japan, on March 11, 2011. After this, significant amounts of radioactive cesium were released into the atmosphere and the ocean.

Dr. Smith's paper said, "The resulting large ocean plume of radioactivity dissipated rapidly … but a significant remnant was transported eastward. By June 2013, the Fukushima signal had spread onto the Canadian continental shelf, and by February 2014 it had increased … resulting in an overall doubling of the fallout background from atmospheric nuclear weapons tests".
