What is nuclear sewage?

The so-called nuclear sewage is the waste water left after the nuclear reactor is cooled.

20 1 1 March 1 1, a "3? 1 1 "The Great East Japan Earthquake triggered a huge tsunami and Fukushima nuclear disaster, causing tens of thousands of deaths. The Fukushima Daiichi nuclear power plant was damaged in the earthquake and tsunami, and dozens of radioactive materials leaked to the outside world.

These radioactive substances have polluted everything around Fukushima, except vegetation, soil, articles, even fine dust and air, as well as nuclear sewage, that is, radioactive liquid.

Nuclear sewage was detected to contain a lot of radioactive substances. According to reports, nuclear radiation can not only kill cells, but also induce mutations, which may induce cell canceration or gene mutation, leading to biological malformation. In a short time, once the intake dose exceeds 100 millisieverts, people will be hurt, and more than 4000 millisieverts will directly lead to death.

Extended data:

If nuclear sewage is discharged into the sea, the consequences will be unimaginable.

Since 20 1 1, more than 1.2 million tons of nuclear sewage have been stored in thousands of large water storage tanks in Fukushima nuclear power plant. Moreover, at present, Fukushima produces about 140 tons of nuclear sewage every day, and all the collected nuclear sewage is stored in nuclear power plants. It is estimated that by 2022, the nuclear sewage will reach the limit of 6.5438+0.37 million tons of water tank capacity.

According to relevant sources, the Japanese government had planned to make a final decision on the treatment method of nuclear sewage in late June 2020, that is, gradually discharge nuclear sewage into the sea.

Because tritium radiation remains in the nuclear sewage to be discharged by the Japanese government, experts predict that once discharged into the sea, these sewage will pollute many places in the world with the Pacific Ocean current.

Japan has basically decided to discharge Fukushima nuclear sewage into the sea. Is it necessary to protect it?
