The USSR Hid a Nuclear Disaster. The CIA Knew. (2026) - The 1957 Kyshtym explosion at the secret Mayak plant, told from Russian sources: what was hidden, who knew, and what the documents actually confirm [00:08:21]
Made this myself, mostly from Russian-language sources (Zhores Medvedev's book, Novosyolov & Tolstikov's "Secrets of the Forty", Mayak records). The last third separates what the documents confirm from what the Western press invented in 1976. Full source list is in the video description. Happy to answer questions.
