For further information about the atmospheric test years topic I'd recommend the movie 'Trinity and Beyond' (https://www.youtube.com/watch?v=gqaq59whOa0). It's build upon declassified military material. Years: 1945 to 1963, Comprehensive Test Ban Treaty.

Finding good and solid information about the russian test program is very hard. There's no "complete" documentation about the whole programm. Most documentaries focus on the ~50MT device the USSR built and detonated.
