(1) Why does Japan discharge nuclear sewage?
On March 11, 2011, an earthquake with a magnitude of 9.0 occurred in the international waters of the Western Pacific Ocean, and a serious accident occurred at the Fukushima Nuclear Power Plant in Japan. Among the six nuclear reactors, No. 1-3 had molten cores and a serious nuclear leakage accident.
Since then, Japan has begun to clean up the Fukushima nuclear power plant. In order to cool the nuclear reactor, it needs to inject a lot of cold water. In the process, the cooling water will be contaminated.
The most important thing is that the cooling water cannot be 100% recycled, which requires continuous reinjection, so nuclear sewage has to be stored.
At this time, Tokyo Electric Power Company, as the operator and manager, began to set aside a piece of land to build water storage tanks to store these nuclear sewage.
But Fukushima is a small place, and even Japan is a small place. It is impossible to build more water storage tanks, and then the problem arises, where to get the newly added 50,000 to 60,000 cubic meters of sewage every year?
In fact, as of the end of 2020, Fukushima’s nuclear pollution water storage capacity has reached 1.23 million cubic meters, while its upper limit is 1.37 million cubic meters.
Faced with this situation, the Japanese played tricks. Do you still remember the Japanese official Yasuhiro Sonoda who drank nuclear sewage 12 years ago?
They began to advocate that the treated nuclear sewage was harmless, and in front of the media, they drank a small sip tremblingly, very frightened.
Since then, Yasuhiro Sonoda has “drinking and becoming famous” and has been promoted step by step, but with the increasing pressure, he has now lost the election and disappeared from the public eye, and stopped social media updates.
In addition, before the Tokyo Olympics, Japan is still working hard to promote that part of the food used in the 2020 Tokyo Olympics and Paralympics comes from Fukushima.
During the G7 summit, Japan repeated its old tricks to pave the way for sewage discharge.
Of course, just doing these things is not enough. Japan also asked the Director-General of the International Atomic Energy Agency (IAEA) Grossi to endorse, claiming that the nuclear contaminated water discharge plan meets international safety standards, trying to convince the international community.
So you see, Little Japan is still very thieves.
Can the nuclear sewage only be discharged into the sea?
In response to this problem, Japan established the ALPS Wastewater Treatment Committee and submitted a report to the International Atomic Energy Agency. There are several preliminary plans:
1. Discharge the sea
2. Steam emission
3. Formation injection
4. Hydrogen emission
5. Underground burial
After nearly 5 years of research, they chose the first one, not because it was the most suitable, but because it was the most economical, and it was also the safest for the local people. Just say that you are immoral!
So in April 2011, Fukushima discharged 115,000 tons of nuclear sewage, and another 300,000 tons in May. This was already severely condemned at the time, but Japan insisted on going its own way and decided to continue on August 24, 2023, which is today. emissions, and will continue to emit for 30 years.
This is really to build your own ease on the disaster of others.
(2) What impact will Japan’s nuclear sewage discharge into the sea have on us?
First of all, it is certain that there must be an impact, and it is not small.
According to the forecast of the team of Academician Zhang Jianmin and Associate Professor Hu Zhenzhong of the Ocean Engineering Research Institute of Shenzhen International Graduate School of Tsinghua University, this batch of nuclear sewage will reach China’s waters in 240 days.
To know whether nuclear sewage is harmful, we need to know what it contains.
1. Tritium (chuān)
A very small amount of tritium has little effect on the human body, but tritium oxides can be absorbed by lung tissue and undamaged skin to the greatest extent, resulting in internal exposure, which will cause serious damage to heredity, reproduction, growth and development.
2. Cesium (sè)
Cesium-137 is highly radioactive, volatile, and active. Cesium-137 in the environment tends to stay in the soft tissues of the body after entering the human body, especially in the muscles. Excessive intake will increase the risk of cancer.
3. Iodine (diǎn)
In radioactive iodine pollution, 131 iodine is a highly toxic nuclide. After entering the human body, it is easy to accumulate in the thyroid gland and damage thyroid cells. When the damage continues to occur, the human body will suffer from hypothyroxinemia, which can even lead to cancer.
4. Strontium (sī)
Strontium is highly toxic. When a large dose of radioactive strontium enters the body, it will cause acute or chronic damage to the body, because strontium has similar chemical properties to calcium, and as a typical bone-loving element, it is easy to affect the calcification of bones and teeth process, leading to distortion, cancer, etc., endangering bone health.
Although the nuclear sewage discharged by Japan has been treated and complies with relevant international safety standards, who can be sure that this standard will be accurate? Is there any problem if you step on this standard line?
These are all things that we need to be careful about, after all, human life is at stake.
Just now, the General Administration of Customs has issued a statement: a complete suspension of the import of aquatic products originating in Japan.
The ridiculous thing is that some experts also refuted the rumors, saying that eating seafood will not be a problem, speaking with international standards. The standard sampling is only a decimal point of the total amount of nuclear sewage. How can such a large amount of discharge be proved by one or two sets of data.
The simplest truth is that clean water without pollution is reassuring.
(3) Is it true that seafood cannot be eaten?
For now, there is no need to worry about it. After all, it has just been discharged, and some sea areas have not yet arrived, and the General Administration of Customs and the food safety supervision department have also clearly stated that they will strictly investigate dead cards and prevent a batch of contaminated Food flows into our country.
Therefore, everyone should eat as much as they want, drink as much as they want, and wait for further news in the future. Life will not be affected for the time being, so don’t worry too much.
(4) Is it necessary to hoard salt?
Since Japan decided to discharge nuclear wastewater on the 24th (today), South Korean people have hoarded a lot of salt, fearing that due to seawater pollution, salt may also pose a safety hazard.
In fact, this is the same as seafood. There is no need to panic. Our edible salt will first be strictly controlled by the food safety supervision department, and secondly, not all edible salt comes from nuclear-contaminated waters.
Japan’s nuclear pollution discharge has taken a tough attitude. This is challenging international credibility and digging its own grave. One day, they will suffer the consequences. wait!
