Eight countries 2055 nuclear tests 71 years
Eight countries. 2,055 nuclear tests. 71 years.
In the name of national security, eight countries have tested nuclear weapons all over the world since 1945, frequently near populated places. North Korea’s claim of hydrogen bomb test draws skepticism, condemnations.
Eight countries have performed nuclear tests. The United States and U.S.S.R. have performed the most explosive tests in history.
“Yield,” a measure of how much energy an explosion releases, is measured in kilotons — one equalling about the power of 1,000 tons of TNT. Both nuclear superpowers have performed nuclear tests with yields of at least 10,000 kilotons (at scale above: ).
The United States is the only country that has used a nuclear weapon in war. Those destructive detonations — in Japan at Hiroshima on Aug. 6, 1945, and at Nagasaki three days later — were just 15 () and 21 () kilotons.
