The testing of nuclear weapons is suddenly a major topic of discussion after being largely dormant for three decades. Last week, Russia tested a nuclear-powered missile, but did not detonate an actual bomb. In response, President Donald Trump said this week the U.S. will resume testing nuclear weapons.

So far in the 21st century, the only country to have conducted nuclear weapons tests is North Korea, and those tests have all been underground. The U.S. last tested a nuclear bomb in 1992. Russia’s last test was in 1990. China stopped in 1996.

The most spectacular nuclear tests were those conducted in the open air in the late 1940s and 1950s, producing some of the most iconic and horrifying images of the nuclear age. The mushroom cloud has been a symbol of the threat ever since.

The devastating effects of those tests are still being felt. The U.S. tests on Bikini Atoll in the Pacific were some of the biggest ever. To this day, contamination from radioactive fallout makes it unsafe for anyone to live there permanently.
