According to the report issued by the Japanese government expert group, five emission modes are put forward. But in the end, they chose the "shortest time and lowest cost" scheme and passed the risk on to the whole world. ...
So, what is in the nuclear sewage discharged every day?
Nuclear waste water may contain radioactive substances, such as cesium (such as 137Cs and 134Cs), strontium (such as 90Sr), tritium (such as 3H) and iodine (such as 13 1I). Especially, 137Cs and 90Sr, two strong carcinogens, can accumulate in organisms and release radiation continuously.
In a word, these nuclides will enter the human body through air, soil, water and food chain after being released into the ocean, which will eventually cause harm to the environment and human health. It may cause chronic radiation sickness and other diseases, and damage organs, endocrine system and nervous system.
Do you feel terrible and angry when you see this? ! Yes, it can even be described as speechless ~
On the other hand, some people don't think so. They think that Japan can rest easy as long as it doesn't eat seafood in the future. Actually, it's not all. Just as food and feed imported from some parts of Japan should be carefully purchased, including Japanese cosmetics, which may also contain radioactive substances. ...
When nuclear sewage starts to be discharged, how long will it take to reach the coast of China?
The macro-simulation results of Tsinghua University-Shenzhen international graduate marine engineering team show that the nuclear wastewater will reach the offshore of China 240 days after discharge.
It is expected to reach the coast of North America in 1200 days, covering almost the whole North Pacific Ocean. Finally, it spread to the South Pacific, and the other side was transferred to the Indian Ocean through the northern waters of Australia.
Despite the strong doubts and opposition of the international community, Japan insisted on announcing that Fukushima nuclear polluted water was discharged into the sea. Faced with such an "unreasonable" country, China has taken measures:
China General Administration of Customs: it is forbidden to import food from ten counties (capitals) such as Fukushima; The Hong Kong SAR Government and the Macao SAR Government prohibit the import of aquatic products from Tokyo, Fukushima, Chiba and other counties 10.
In the face of Japan's nuclear wastewater discharge, how should people guard against it?
The first is to stop using seawater (referring to coastal areas, especially coastal rural areas) and avoid contact with and eating contaminated seafood, especially raw pickled seafood. If you want to go to a regular shopping mall to buy food, try to avoid eating imported squid, saury, cod and mingtai fish.
You should also drink less tea or not. Why do you say that? It is because tea contains components such as sulfuric acid, sulfite or nitrate, which will prolong the metabolic cycle of 13 1I and increase the harm of radioactive substances to human body. You can eat more selenium-containing ingredients, because selenium will promote the discharge of 13 1I, such as broccoli, mushrooms, garlic and so on. These ingredients are high in selenium, and you can also eat brand selenium-enriched rice.
Also, if you accidentally eat radioactive food, don't panic ~ generally it won't do much harm to your body. However, a large amount of intake will cause fatigue, loss of appetite, diarrhea, vomiting and other discomfort, and it is necessary to seek medical attention in time.
In a word, we should not be too alarmed in the face of Japan's nuclear wastewater discharge. Usually, you should learn more protective measures on the network. Besides paying more attention to your daily diet and supplies, you should also keep a rational and calm mind, and don't listen to and spread rumors. Only in this way can we effectively deal with possible nuclear pollution problems.
