Fukushima nuclear power plant will discharge nuclear wastewater Yahoo poll: 2/3 participants oppose the practice
[Yahoo News Report]The Japanese government plans to discharge the diluted nuclear wastewater from the Fukushima Daiichi Nuclear Power Plant into the sea this summer, and China and many other countries have voiced opposition. In Hong Kong, the Secretary for the Environment and Ecology, Tse Chin-wan, once stated that the discharge of nuclear waste water into the sea is definitely not an act of a responsible country. As long as Japan discharges waste water, the Hong Kong government will immediately restrict the import of Japanese food that may be affected. “Yahoo Poll” once asked regarding the above issue, “Japan plans to discharge Fukushima nuclear wastewater into the sea this year. The discharge period may reach 30 years. Do you agree with this approach?” In the end, nearly 16,000 people voted, and 2/3 of the participants They all expressed their disapproval of the discharge of nuclear wastewater into the sea, believing that “it will affect the marine ecological environment and public health.”

The poll was conducted from the 15th to the 22nd of this month, with 15,726 participants. 18.3%, or nearly 2,900 people, agreed that Japan would discharge nuclear wastewater into the sea, because “Japan will ensure that the nuclear wastewater is harmless before discharging into the ocean to avoid environmental pollution”; 66.9%, or more than 10,500 people, disagreed that Japan would discharge nuclear wastewater Sea discharge, because it will affect the marine ecological environment and public health; another 14.8%, or more than 2,300 people, said they had “no special opinion” on this issue.

Yahoo Poll: Japan’s Fukushima “Nuclear Wastewater Discharge” Controversy
The Hong Kong government pointed out that an inter-departmental task force has been set up in response to Japan’s plan to discharge nuclear wastewater, and that the Center for Food Safety will conduct testing for food imported from Japan. Huang Jielong, the founding president of the Hong Kong Japan Food and Cuisine Industry Association, estimated earlier that products from Fukushima, Miyagi, Iwate, Ibaraki and Chiba prefectures would bear the brunt.
During the 3.11 Great East Japan Earthquake in 2011, a nuclear leak occurred at the Fukushima Daiichi Nuclear Power Plant. Tokyo Electric Power Company injected a large amount of seawater in order to cool the nuclear fuel. The Japanese side stated that the container for storing waste water is full, so the nuclear waste water must be discharged. They stressed that nuclear wastewater would be diluted to safe levels and the practice was monitored by the International Atomic Energy Agency (IAEA). Earlier this month, an IAEA working group completed its final review in Japan.
The tritium content of Japanese nuclear wastewater is 1/7 of the WHO standard
The Japanese side stated that they will use the Advanced Liquid Processing System (ALPS) to treat nuclear wastewater; the IAEA said that ALPS can remove 62 kinds of radioactive elements, except for tritium. As a radioactive substance, tritium also exists in the natural environment. The substance itself has a luminescent function and can be used for lighting and other purposes. The half-life of tritium is as long as 12.32 years, but if it is contained in water, the half-life will be greatly shortened to 7 to 14 days, which means that following the human body absorbs tritiated water, the tritium content in the body will decrease within two weeks. cut in half.
According to the Ministry of Economy, Trade and Industry of Japanthe tritium-containing wastewater treated by ALPS, the tritium concentration shall not exceed 1,500 Bq per liter (Becquerel, Bq); and according to the drinking water standard of the World Health Organization, the tritium concentration shall not exceed 10,000 Bq per liter.

China’s nuclear power plants discharge tritium-containing water content exceeds Fukushima
Japan’s Ministry of Economy, Trade and Industry stated that the total annual tritium discharge from the Fukushima Daiichi Nuclear Power Plant’s tritium-containing wastewater will not exceed 22 trillion (22 trillion) Bakers. The Ministry of Economy, Trade and Industry also pointed out that nuclear power plants in many countries in East Asia have discharged tritium-containing liquids. Taking China’s Qinshan Third Nuclear Power Plant as an example, the nuclear wastewater discharged in 2019 contained regarding 124 MB of tritium; South Korea The nuclear wastewater discharged by the Guli Nuclear Power Plant in 2019 had a tritium content of regarding 91 MB; the nuclear wastewater discharged by Taiwan’s Ma’anshan Nuclear Power Plant in 2019 had a tritium content of regarding 35 MB.
