China News Service, Beijing, May 26 (Reporter Ruan Yulin) The Ministry of Ecology and Environment of China released the "2021 Bulletin on the Status of China's Marine Ecological Environment" in Beijing on the 26th, showing that the western Pacific waters are still affected by the Fukushima nuclear accident in Japan.

  On March 11, 2011, a large earthquake occurred in the waters off northeastern Japan and triggered a tsunami, resulting in the highest level of radioactive material leakage at the Fukushima Daiichi nuclear power plant.

The accident resulted in the meltdown of the cores of Units 1 to 3 of the nuclear power plant and the leakage of a large amount of radioactive material.

Tokyo Electric Power Company injected a large amount of water to cool the molten fuel rods in the abandoned nuclear reactor. Rainwater and groundwater in and around the nuclear power plant were also contaminated by radioactive substances. Over the past 10 years, millions of tons of nuclear-contaminated water have been accumulated.

  In 2021, China will conduct marine radioactivity monitoring at 147 points in the waters under its jurisdiction, the waters adjacent to 12 nuclear power bases and the waters of the Western Pacific Ocean.

According to the communiqué, the western Pacific waters are still affected by the Fukushima nuclear accident in Japan, and the activity concentration of cesium-137 in seawater remains at the same level as the previous year.

  According to the communique, the activity concentration of natural radionuclides in marine organisms in coastal waters is at the background level, and there is no abnormality in the activity concentration of artificial radionuclides.

The activity concentrations of radionuclides related to facility activities in the seawater, sediments, marine organisms and other environmental media around the nuclear power base are generally within the range of fluctuations over the years.

The evaluation results show that the radiation dose to the public caused by the operation of each nuclear power plant is far lower than the dose limit set by the state, and has no impact on environmental safety and public health.

  The 2021 Bulletin on the State of China's Marine Ecological Environment is jointly prepared by the Ministry of Ecology and Environment, the Ministry of Natural Resources, the Ministry of Transport, the Ministry of Agriculture and Rural Affairs, and the State Forestry and Grassland Administration.
