Despite 35 years, the most dangerous nuclear reactor accident ever is an amazing story to this day. From the experimental spirit of chief engineers and operating personnel to the already poorly designed reactor and post-disaster wine clerk to official denials and side talks.
It took 68 hours for a 42-word statement from the Soviet News Agency to be issued. By this time, they already knew in Europe that something big, unmanageable, had happened at the nuclear power plant 120 kilometers from Kiev. Specifically, an astonishing amount of radioactive material leaked into the atmosphere and spread across the continent.
For the first time in Sweden, a sudden rise in extremely high levels of radioactive radiation was observed. Since nothing happened around their home, it didn’t take long for them to quickly realize the source of the heavenly grace: the meteorological data, and the movements of the air, clearly showed that it was around Chernobyl.
And where it spread it was only controlled by the whims of nature.
In the days following April 26, 1986, tornadoes and actual currents swept through the aggressive substances north and northeast. Finding Scandinavia, especially Sweden. We approached clouds for the first time in the 30’s (radioactive cloud wants to be just a plastic name, not in the shape of a sheep or cauliflower like clouds of water vapor, but a collection of large airborne amounts of radioactive material), and more specifically the northwestern part of the country, my county Gyor Sopron and Fez. In Szombathely So he jumped up Measured radiation.
On the other hand, Austria received a heavy dose.
However, by May 1, to celebrate the action, they also swam over the interior of Hungary. Even if the data were not accurate, the Hungarian party leadership certainly knew the true dimensions of the disaster. However, they found a good idea to hold regular rallies, and while they were preparing for an emergency in Europe, Janus Kadar and members of the Central Committee waved back from the amphitheater of Budapest’s Parade Square to the masses of workers carrying flags and placards. We can also say with radiant joy.

We must have been lucky. After all, the unusual radiation in the early days mostly avoided us. However, it didn’t help that there were thunderstorms across the country on May 1. This is because heavy rain was actually washing the air. This is why we feel much cleaner after a severe thunderstorm. It also brings greater quantities of radioactive material to the earth at this time (wet deposition) compared to periods of drought (dry precipitation).
In the next few days in May, the situation changed, with radioactive material reaching us from the east in a shorter way, straight ahead.
This was our second dose.
However, the thunderstorms have disappeared, so only radioactive materials can reach the Earth’s surface in a less dense and dry way. It was not like this in Austria, where a thunderstorm zone passed by us, washing off another potion from the neighbors.
After May 3, the third part of the polluted air from us arrived from the south and southeast, mostly over Transdanubia. But the rain struck our western neighbor again, we are still fleeing the drought. From the fifth and fourth time, and then again from the East we received a renewal, but already in diminishing focus.
Nuclear power plants are powered by various isotopes of uranium, which gain energy via nuclear fission. Decomposition processes generate a number of new radioactive materials, more than twenty of which have been released in Europe. I was fortunate enough to have written my ELTE dissertation from Chernobyl and processed a previously unprocessed dataset.
One of them is also one of the radioisotopes Cesium-137. Also in Hungary, the largest amount of this was settled. The half life (the time at which half of its value collapses) is 30 years, which means that half of it is now over. Although the iodine analogue is also dangerous (which is why iodine tablets are usually taken so that primary iodine displaces the iodine analogue from the thyroid gland), its half-life is only eight days.
However, there is still debate to this day about how many people were injured or killed directly or indirectly due to the accident. According to estimates About 0.02 percent of the hazardous substances released from the exploded power plant fell in Hungary between April 29 and May 5. We received 0.06% of the total radiation emitted from Chernobyl. This is certainly only a fraction of the dose for the Ukrainian, Belarusian and Russian lands.
And we can say that we are fortunate to have a disaster nearby that hit us so badly that we did not face it Chernobyl Radioactive areas became dangerous in Europe List. However, our third neighbor, Austria, is in third place (Sweden is in first place, followed by Finland). And we can think, if it hadn’t happened that way, but if we had been exposed to radiation, the KDAR system, which is unacceptable to everyone, would have pulled out even in the next two years. The Soviet Union did not withdraw for long either, although it was likely that it was just one of the last nails in its coffin. What should we do with them?
