Is Japan s nuclear leak really that serious? How much impact will it have if I want to study in Toky

I want to go to ...... too

Some people say that it is so serious that if you don't deal with it, the whole of Asia will be radiated, and some people say that in fact, the so-called severe radiation in Tokyo is just as ...... as going to the hospital to take an X-ray

But I feel like it's going to pass, and it shouldn't have any effect.

The Fukushima area may be a bit more serious, but Tokyo is fine, I have friends and relatives in Tokyo, and they are fine. If you have concerns, you can postpone it for two years from what you originally planned. If it were that serious, Tokyo would have become an empty city.

The Fukushima Nuclear Power Plant is located in the Fukushima Industrial Zone of Japan. It is currently the largest nuclear power plant in the world, with a total of 10 units all boiling water reactors. On March 12, 2011, the Ministry of Economy, Trade and Industry's Nuclear Safety and Security Agency announced that radioactive materials from the Fukushima Daiichi Nuclear Power Plant had leaked to the outside as a result of the impact.

Radioactive elements have a half-life, and the so-called half-life refers to the time it takes for half of the nuclei of radioactive elements to decay. Its half-life decreases exponentially over time, but it should be noted that as long as there is one atom at the end that has not decayed, the radioactivity of the element will not disappear. Generally speaking, after 30 decay periods, its radioactivity will drop to a state that is basically undetectable, and there is no danger to humans.

(Take no as an example).

The main radioactive materials found around the nuclear power plant are iodine (I) 131 and cesium (CS) 137, which are used as an estimate. Iodine-131 has a half-life of 8 days and cesium-137 has a half-life of 30 yearsBased on a half-life of 30 halves, it takes about 900 years for cesium (CS)137 to decay to the point where it is harmless to humans. At the same time, it should be noted that the duration of the half-life is not related to the external physical and chemical environment, which means that we cannot shorten the radiation time by changing the half-life.

In addition, the ionizing radiation produced by the leaked radioactive materials will form free radicals after invading the molecules of living organisms, and then damage proteins, DNA, and cell membranes, causing abnormal and irreversible mutations in animals and plants, which is why there are so many deformed plants and animals around nuclear power plants.

It may be that no matter how many teenagers there are, such damage cannot be reduced, so this is very serious.

Because this kind of damage is really too harmful to the human body, but for many more years, this kind of damage has always existed.

And leakage will not be harmless to the human body for many years, it will always be harmful to the human body, and it will always affect people's living environment and body.

No matter how many years after the nuclear leak, the impact will still be there, but the problem will be alleviated after many years.

Based on a half-life of 30 halves, it takes about 900 years for cesium (CS)137 to decay to the point where it is harmless to humans.

No matter how many years have passed, nuclear leaks have been harmful to people, after all, the chemicals are not so easy to digest.

The impact of nuclear leakage is significant, some of which will be harmless to humans after hundreds of years, and some of which will be permanently polluted.
