Wastewater produced after the Fukushima nuclear accident in Japan contains many radioactive elements. Most of the radioactive material is removed from this wastewater and most of it remains.
1.Tritium: Tritium is the main radioactive element still present in wastewater treated in Fukushima, Japan. It is a radioactive isotope of hydrogen that is usually produced when nuclear reactions occur.
2.Strontium and cesium: In untreated wastewater, radioactive materials such as strontium-90 and cesium-137 are present. These elements have a long half-life and are radioactive, and when treated, their levels are greatly reduced.
3.Iodine, Radon, Radium: In addition, wastewater may also contain other radioactive materials such as iodine-129, radon-222, radium-226, etc.
It is important to note that while treatment facilities can remove most radioactive materials, current treatment technologies are not effective in removing tritium from wastewater.
The global scientific community and international environmental organizations have always maintained a high degree of concern and caution towards the treatment and discharge of nuclear wastewater in Japan. Although some radioactive elements cannot be completely removed, scientific research institutions are working to find more effective treatment options. It is hoped that scientists can find ways to deal with it that are both economical and environmentally friendly, and harmless to humans and the ecological environment. All influencing factors, including environmental, health, and social and economic impacts, should be fully considered before any decision is made to take action.
At 1 p.m. on August 24, 2023, Japan** ignored the strong doubts and opposition of the international community and unilaterally forcibly started the discharge of contaminated water from the Fukushima nuclear accident into the sea. What Japan has done is to pass on the risks to the whole world, to pass on the pain to future generations of mankind, to become a destroyer of the ecological environment and a global marine polluter, to violate the rights to health, development and environment of the people of all countries, and to violate its own moral responsibilities and obligations under international law. Japan has discharged the nuclear-contaminated water, and at the same time put itself in the international dock, which will surely be condemned by the international community for a long time. China has always adhered to the supremacy of the people and will take all necessary measures to safeguard food safety and the health of the Chinese people.
