Recently, Japan's Ministry of Health, Labor and Welfare released the news that after testing a batch of marine fish, it was found that a marine fish called "Koshi flat carp" caught off the coast of Fukushima Prefecture exceeded the radiation standard. The radioceutium activity detected from this fish reached 1400 becquerels per kilogram, exceeding the Japanese food standard of 100 becquerel per kilogram by 14 times.
After the test results were announced, in order to "stop the loss in time", Japan quickly suspended the sale of this marine fish in the market. What people did not expect was that this kind of marine fish called "Xu's Flat Carp" was included in the scope of suspension as early as February last year, and was later allowed to sell.
Over the past few years, Japan has suspended the sale of 44 seafood products over concerns about the contamination of seawater from the fukushima nuclear power plant in 2011 due to concerns about the spill of radioactive material from the Fukushima nuclear power plant. The Japanese, who had a sense of luck, somehow lifted these restrictions.
The leak of the Fukushima nuclear power plant 11 years ago is frightening
On the afternoon of March 11, 2011, a magnitude 9.0 earthquake occurred in the Pacific Ocean, 373 kilometers from Tokyo, Japan, the fifth largest earthquake in history. The huge energy released by the earthquake set off a tsunami of up to 25 meters in the Pacific Ocean, and the Japan Meteorological Agency responded quickly and issued a tsunami warning.
However, in the face of great natural disasters, human beings appear very small and helpless. Huge tsunamis rushed in, and tsunami warnings could alert people along the coast to evacuate, but the epicenter of the earthquake was only a few hundred kilometers away from Japan, and the tsunami waves moved at a speed of up to 800 km/h offshore, rushing to land in just a few tens of minutes.
According to Japan's post-disaster data assessment, the March 11 earthquake caused a total of 27,593 deaths and disappearances in 12 prefectures. This means tens of thousands of families have been destroyed and hundreds of thousands of people will be immersed in the grief of losing loved ones, and that doesn't include those who are homeless.
When a tsunami strikes, people instinctively run away from the coastline, but the Fukushima nuclear power plant in the Fukushima Industrial Zone is helpless and can only engage the oncoming tsunami head-on.
As a result of the earthquake and tsunami, the nuclear facilities at the Fukushima Nuclear Power Plant in Japan were damaged and a serious leak occurred, leaking about 300 tons of highly contaminated nuclear radiation water from the storage tanks of the nuclear power plant.
Even more worrying is the need to continuously inject cooling water into the Fukushima nuclear facility in order to cool the reactors, and these waters containing radiation are still being discharged into the Pacific Ocean.
Some experts believe that the continuous production of radiation wastewater at the Fukushima nuclear power plant has reached 335,000 tons. In order to store this radioactive water, Japan has built thousands of water storage tanks around the nuclear power plant, but the water has not been well treated, and the final treatment plan is still diluted and discharged to the Pacific Ocean.
Japan's treatment of nuclear wastewater has been questioned by many groups, including the IAEA and Japanese media, and as early as 2011, radioactive elements leaked from the Fukushima nuclear power plant had spread to the Arctic Ocean.
It's hard to imagine how much the radioactive elements leaking from the Fukushima nuclear power plant have affected the Earth's environment over the past 11 years. After these radioactive elements enter the ocean, they not only pollute the seawater, but also pose great challenges to the survival of seawater organisms.
"Radiation fish" is also a fish, what will happen if you eat it?
After the fukushima nuclear power plant leak, a new term emerged, that is, "radiation fish". Scientists generally believe that both inshore and harbor fish that are contaminated with nuclear contamination should be included in the range of radioactive fish.
The essence of nuclear radiation is some ultrafine particles with high energy. Under the action of nuclear reaction, neutrons and protons that were originally bound by atomic nuclei will collide around at a very fast speed.
These superfine particles, like "wild horses" that have lost their reins, attack other nuclei, essentially changing the structure of the atom. This kind of change in the microscopic world, the result can be imagined, almost all organisms exposed to nuclear radiation, will have different degrees of genetic mutations and lesions.
Canada's whitefish, Alaska salmon and Pacific herring, among others, were found to be affected by nuclear radiation in the years that followed, and they suffered from disease and even died.
After the Japanese nuclear leak, the content of radioactive cesium in the body of a captured thick-headed flat carp reached 254,000 becquerels. The radioactive content of this "high-radiation fish" has exceeded 2540 times the normal use of standard radiation.
The ocean itself is a complete ecological chain, fish in the food chain layer by layer, these can not be absorbed radioactive elements, will continue to accumulate at the top of the food chain, continue to accumulate.
If humans mistakenly eat this "radiation fish", the consequences can be imagined, light dizziness and headache, loss of appetite, heavy will lead to tumors, leukemia and other diseases.
After 11 years, the shadow of the Fukushima nuclear leak still lingers
Japan's TEPCO, which is responsible for nuclear wastewater treatment, has been trying to publicize to the outside world, saying that they discharge nuclear wastewater into the ocean, with minimal impact on the environment and the human body, and is a trustworthy way.
Is this really the case? Eleven years after the Fukushima nuclear accident, the shadow left on the locals still lingers.
Many people think that since the nuclear power plant has been destroyed, it will either be repaired and reactivated, or dismantled, and it should not be so troublesome to deal with. That's right, looking at Japan's progress in disposing of the fukushima nuclear power plant's abandoned facilities, you know how difficult it is.
To this day, a large amount of nuclear debris formed by the core melted in the first nuclear power plant has remained motionless. If these nuclear residues cannot be effectively cleaned up, it will be difficult to carry out the subsequent treatment work.
In order to deal with these nuclear residues, Japan has specially developed an unmanned robotic arm, and the robotic arm used for operation will not start working until the year. According to TEPCO's plan, the nuclear waste will be cleaned up in the next 30 years, but many people are skeptical about it.
In addition to nuclear wastewater and debris, more than 27,000 people are currently uprooted from their homes because of Fukushima nuclear radiation. With the continuous progress of the level of technology, the use of nuclear energy by human beings is becoming more and more extensive, but how to deal with nuclear waste is still a difficult problem.
Under the influence of ocean currents, the nuclear radiation water discharged by Japan into the Pacific Ocean is likely to reach all corners of the world. This time, Fukushima Prefecture, Japan, has found radiation fish again, which should sound a wake-up call for Japan, if these nuclear wastewater and nuclear waste residue are not properly treated, it is Japan itself that will suffer in the end.
On the other hand, if the radiation fish appear in turn off the coast of Japan, why shouldn't Japan beg for itself? Nature is fair, and the more you pamper and protect her, the gentler and friendlier she becomes; and if you take and destroy endlessly, she will lose her temper.
