Core Points - The article discusses Japan's decision to release treated radioactive water from the Fukushima nuclear power plant into the Pacific Ocean, a plan that has faced significant opposition from neighboring countries, particularly China [1][3][5]. Group 1: Japan's Plan and Implementation - Japan's government decided in April 2021 to gradually release over 1.3 million tons of treated radioactive water into the ocean, with an annual release of 220 trillion becquerels of radioactive material expected to last for 30 to 40 years [1][5]. - The water is treated using the ALPS system, which removes most radioactive substances but cannot filter out tritium, necessitating dilution before release [1]. Group 2: International Reactions - China has been particularly vocal against Japan's plan, claiming it poses risks to marine life and food safety, labeling Japan's actions as selfish and dismissive of international concerns [3][5]. - Other countries, including South Korea, Russia, and some Pacific island nations, have also protested against Japan's decision [3].
