On April 13, the Japanese government decided to dispose of nuclear waste water from the Fukushima nuclear power plant accident by means of ocean discharge, which caused an uproar in the world.
The so-called nuclear waste water is the waste water left after cooling the nuclear reactor.
According to research by Japanese experts, the main pollutants in nuclear waste water are tritium and other radioactive substances, and their respective half-lives are different.
The half-life of tritium is about 12.43 years, the half-life of cesium-137 is 30 years, and the half-life of strontium-90 is 29 years. None of their hazards can be eliminated in a short time.
According to a report issued by the "Greenpeace" in October last year, the large amount of tritium and carbon-14 contained in Fukushima nuclear waste water will greatly increase the radiation dose received by humans, and there is a potential danger of harming human DNA.
In the words of Sean Bernie, a senior nuclear expert at the organization, harmful elements and other radioactive nuclear waste in wastewater will harm the environment for thousands of years.
In addition, these radioactive materials can easily enter marine sediments and be absorbed by marine life.
Not only are they potentially toxic to humans, but they can also affect the marine environment in a more permanent and complex way.
Unfortunately, the earth cannot speak.
If the earth had thoughts and life, she would definitely turn around and flee, and would never accept this cup of nuclear waste water "respectfully" by Japan.
Preventing nuclear waste water from polluting the ocean is not only protecting the earth, but also protecting man’s own health, life and future.
