73 years ago, in the morning of August 6, 1945 at 8:15 the atomic bomb was dropped on the Japanese city of Hiroshima. The American bomber had the imposing name of “Enola Gay” (it was named after the mother of the commander of the crew) and the deadly bomb with the affectionate nickname "Little boy" and energy of 20 kilotons of TNT. "Little boy" claimed about 130 thousand human victims in a few seconds, most of which turned into radioactive dust, tens of thousands of people were left without a roof over their heads. Three days later, on August 9, a Nagasaki city was subject to a similar blow from the bomb with a no less peaceful nickname "Fat Man," the consequences were terrible as well [3]. According to some reports, the Americans, wishing to achieve Japan's surrender, planned to make three nuclear attacks in total, but as of early August 1945, only two deadly bombs were available to the US military. At that time, few could have guessed how terrible and irreversible the consequences of a nuclear attack could be. The incidence of leukemia has increased 18 times. Victims of this terrible atomic bomb attack continue to die of radiation exposure so far, adding 5,000 names to the list of victims annually [1]. To date, the number of victims of the tragedy has approached 450 thousand. The US Air Force Colonel, who ordered from the escort aircraft to drop the bomb, soon went crazy, and spent the rest of his days in a psychiatric hospital.
