The Pacific Ocean – in fact almost one-third of the Globe – is thought to have been contaminated from the leak out from the Fukushima Nuclear Disaster.
The International Atomic Energy Agency (IAEA), seeking to promote the peaceful use of Nuclear Power, in 2011 established with the Regional Cooperative Agreement (RCA) Member States, a joint IAEA Technical Cooperation (TC) project in the region of the Pacific Ocean. It was established after the Fukushima disaster when a tsunami caused by a major earthquake on 11 March 2011, disabled the power supply and cooling of three Fukushima Daiichi reactors, causing a nuclear accident. As a result a large quantity of radioactive material was admitted into the Pacific Ocean.
The massive expansion of ocean had diluted it substantially so radioactivity remained at low levels but there was still concern over contamination of seafood even at these low levels. The marine monitoring project was therefore, established to ensure that the seafood of the region was safe for consumption and to maintain a comprehensive overview and full facts of the situation, considering its grave implications.

The TC is due to conclude this year. A few results have caused concern. A field study they conducted on 2 July 2014, revealed from two sets of seawater samples, found that two filter cartridges were coated, which showed elements of cesium, a radioactive substance.
Then recently, trace amounts of cesium-134 and cesium-137 turned up in samples collected near Vancouver Island in British Columbia. The samples collected were separate from the monitoring project set up by IAEA but it is thought the only possible source of these radioactive elements is Fukushima, according to the Integrated Fukushima Ocean Radionuclide Monitoring (InFORM) Network. This is the first time that traces of cesium-134 had been detected near North America .
While these are trace amounts, the danger of radioactive material in any amount cannot be underestimated. However, the experts say that these levels detected cannot really harm us, they are still lower than those we could be exposed to from a dental x-ray for instance.
