Radioisotopes have been detected in the air of many countries in northern Europe. Why are people afraid of exposure to radioactive isotopes, and all countries strictly monitor radioactive isotopes in the air? Because exposure to radioactive isotopes will lead to gene mutation, which will induce various cancers and greatly increase the risk of cancer, which will lead to an increase in mortality.
There is an organization that monitors radioactive isotopes in the air, called the Comprehensive Nuclear-Test-Ban Treaty Organization, or CTBTO for short.
On June 22nd and 23rd, 2020, CTBTO detected abnormal contents of radioactive isotopes Cs and Ru in Stockholm, Sweden, but it was harmless to human body.
Radioisotope anomalies were also found in the monitoring report of the Estonian Environmental Protection Bureau on the 28th, and then a small amount of radioisotopes were detected in Finland and Norway.
Raassina, head of CTBTO? Zerbo released a map showing the possible range of radioactive isotope sources, covering northwest Russia, Finland and Du Nan, Sweden and the Baltic Sea.
Dutch officials claimed that the source was Russia. After Russia denied that the British BBC28 reported on the 28th that many countries had detected radioactive isotopes, a Dutch official claimed that the source of radioactive isotopes might come from northwest Russia.
Russia quickly denied this statement, saying that the Leningrad nuclear power plant and the Kola nuclear power plant in the northwest region were operating normally, and the surrounding radiation levels were within the standard range, and no accident reports were received.
The person in charge of CTBTO said that the bound particles monitored this time are related to nuclear fission and may come from civilian sources.
The specific radioactive isotope source is unknown. According to the regional analysis of the source of radioisotopes by the head of CTBTO, in addition to the two Russian nuclear power plants officially named by the Netherlands, there are also nuclear power plants in Sweden and Finland. One more thing, two nuclear power plants in Sweden have been abandoned and are ready to be demolished. I wonder if it is possible that nuclear particles leaked during disassembly.
The source of specific nuclear particle leakage is still under investigation, and the source is still unclear. Everything is just an inference.
The advantages of nuclear power plants and the dangers of nuclear leakage are really many, but nuclear leakage is also very terrible. What are the advantages? I will briefly list the benefits of nuclear power plants:
Unlike fossil fuel power generation, nuclear power generation will not emit a lot of waste pollutants into the air, thus reducing air pollution. Conducive to slowing down the greenhouse effect. Power generation by nuclear power plants is cheaper and cheaper than other traditional power generation methods. The energy density of nuclear fuel produced by nuclear power plants is several million times higher than that of fossil fuels, and the volume occupied by nuclear power plants is much smaller, which is more convenient for transportation and storage. Nuclear leakage from nuclear power plants will directly lead to canceration of human cells, which in turn will lead to cancer, so the supervision of nuclear particles is very strict all over the world.
