Marshall Islands
The Marshall Islands are a location you definitely don't want to go near, even though most people would probably rank Chernobyl at the top of their list of locations they wouldn't want to visit due to their concern about radiation exposure. The location of American nuclear weapon testing is still roughly ten times more radioactive than Chernobyl after more than 60 years.
On July 25, 1946, a bomb on the Bikini Atoll in the Marshall Islands detonated for the first time. They conducted the first hydrogen bomb test there five years later. They tested a bomb that was 1,000 times more potent than the one that exploded over Hiroshima three years later.
The Marshall Islands were the site of 67 distinct nuclear weapon tests, and the destruction is evident from space. The Dome, an enormous crater containing 85,000 cubic meters of radioactive waste buried in concrete, may be found on one of the islands. The region will flood if sea levels rise further, and radioactive waste would likely escape.
