More than twenty years have passed since the accident at the Chernobyl nuclear power plant. And all this time, disputes about why the accident occurred, whether it was inevitable, whether everything was done correctly and enough to localize the accident, eliminate its consequences, medical and socio-economic protection of the population do not subside. But, nevertheless, there are still questions that make us return to Chernobyl problems again and again, because Chernobyl is not only our past, it is our present, and maybe the future, if you do not try to fully understand the causes and consequences of what happened. "To figure it out," of course, it is loudly said: so many truths, truths, myths and outright lies intertwined that it would seem difficult to separate the grains from the chaff. It is significant that after more than 20 years, not a single apocalyptic forecast, fortunately, did not come true, and could not come true.
