This photo archive tells about the work of the expert group of our foundation at the Semipalatinsk nuclear test site in the period 1997-2000. Given the great experience gained in those years and the relevance of this topic in the modern world, it was decided to continue the work begun to help people, the environment and the planet. The goal of our foundation is to prevent the repetition of past global mistakes during the Cold War and use the atom only for peaceful purposes.
