The International Atomic Energy Agency (IAEA), which seeks to promote the peaceful use of nuclear energy , established in 2011 with the Member States of the regional cooperation Agreement (RCA), a set of IAEA technical cooperation (TC) in the Pacific Ocean project. It was established after the Fukushima disaster, when a tsunami caused by an earthquake on March 11, 2011, off the power supply and cooling of three reactors Fukushima Daiichi, causing a nuclear accident. As a result he was admitted a large amount of radioactive material into the Pacific Ocean.
Of no surprise, this caused great concern to the countries, extracted from the Pacific Ocean because of the potential economic and environmental consequences. The aim of the project was TC, therefore, to control the presence of radioactive substances in the marine environment. Scroll down for video. The first annual review meeting held in August 2012 showed predictive hydrodynamic models and predicted that the strong current known as the Kuroshio Current and its extension, had the capacity to transport of radioactive materials through the Pacific Ocean toward East.
A field study found that two were coated filter cartridges, which showed elements cesium, a radioactive substance. The TC should be concluded this year. Some results have caused concern. A field study was conducted on July 2, 2014, revealed from two sets of samples of seawater, it was found that two were coated filter cartridges, which showed elements cesium, a radioactive substance. Then recently, traces of cesium-134 and cesium-137 was presented in samples collected near Vancouver Island in British Columbia. The collected samples were separated from monitoring project established by the IAEA, but the only possible source of these radioactive elements Fukushima is, according to the Integrated Ocean Tracking Radionuclides Fukushima (Inform) network system is created. This is the first time that traces of cesium-134 had been detected near North America. While these are traces, the danger of radioactive material in any quantity can not be underestimated.
However, experts say that these levels detected can not really hurt us, remain lower than those potentially exposed from a dental x-ray for example. Having said this, every possible exposure, any small amount adds. The problem with nuclear energy and rain, radiation and radioactive materials can travel far and wide, with the wind and the sea. Therefore, we must aim globally to maintain these levels to zero. In any case, the continuous monitoring of the oceans to be carried out, according to Ken Buesseler, a marine chemist at the Woods Hole Oceanographic Institute is required.
The Buesseler says should be taken into account beyond 2015, particularly from the board of the IAEA is to dump more polluted water into the sea. This is apparently more desirable than keeping it in tanks. Any discharge will have to be controlled, and continuous monitoring is needed, particularly near the plant to improve reliability of the data. This is of concern not only to state authorities. Consider fishermen. Every time catching fish in the ocean, fish need to be tested for radioactivity. Before any further dumping is made, the IAEA and Tokyo Electric Power Co., which control the plant, must take into account not only the environmental impact, but the socio-economic impact. Livelihoods could be affected and the long-term health of the region and the global community over time.
