THE CLOSURE OF THE SEMIPALATINSK NUCLEAR TESTSITE IS THE BEGINNING OF THE PATH TO A UNIVERSAL BAN ON NUCLEAR TESTING
Scientists were the first to speak about the negative consequences of nuclear tests conducted in the USSR, the USA, Great Britain and France already in the 50s of the last century. After the conclusion of the Treaty on the Prohibition of Nuclear Tests in the Atmosphere and Under Water in 1963, underground tests continued in these countries. New members of the "nuclear club" have appeared. The paper analyzes the reasons and conditions for the beginning of a universal ban on nuclear weapons testing. The Comprehensive Nuclear-Test-Ban Treaty entered into force only thirty years after the closure of the Semipalatinsk nuclear test site.
