Year of first detonation: Number of detonations: Each explosion is represented by a circle. Many of these circles overlap. atmospheric underwater Country: United States underground 912 1945 206 5 USSR 1949 223 756 Filled circles are atmospheric detonations United Kingdom 1952 21 24 1960 1964 France 50 160 Hollow circles are underground or underwater tests China 22 26 Israel? The size of each circle represents the yield of the blast. The scale is not linear: 1967 ?
