American hurried Japan to return plutonium

Plutonium is a radioactive transuranic elements of American Scientists first discovered the element in 1940 and it is currently being used in nuclear weapons and nuclear reactors. Compared to other radioactive elements, the greater the risk of plutonium, once into the human body, plutonium will be lurking in the lungs, bones and other tissue cells, genetic damage cells, raising the risk of cancer, according to Xinhua News Agency

Japanese media quoted the 26th in Japan and the United States government news sources reported that the United States is urging Japan returned more than 300 kilograms of plutonium radioactive substances. Reported that the United States during the Cold War put these radioactive substances to Japan for study, most of them weapons-grade plutonium.

This exclusive Kyodo news release on the 26th. Reported that during the Cold War the United States had handed over 331 kilograms of plutonium in Japan, most of the abundance of weapons-grade plutonium for nuclear research. Kyodo said these plutonium present in Naka-gun, Ibaraki Prefecture, Japan Tokai-mura used for fast reactor fuel.

U.S. President Barack Obama took office stressed that the implementation of nuclear safety-related policies, said the United States, in order to avoid the risk of radiological materials from falling into the hands of terrorists, the need to eliminate or minimize the use of nuclear material. U.S. subsequently returned to Japan made this batch of plutonium requirements.

Kyodo News reported that Japan strongly opposed the return of the original batch of plutonium on the grounds that these fast neutron reactor plutonium needed for research in Japan. According to Kyodo publicly available data, there is another Japan is now about 44 tons of plutonium, but the quality of these plutonium insufficient for research purposes, but the United States over the past few years, repeated requests, the Japanese finally agreed to return.

Since 2011 Japan earthquake and tsunami triggered nuclear crisis, the United States has repeatedly expressed concerns about Japan’s use of nuclear material security.
