List of nuclear accidents

This is a list of notable accidents involving nuclear material. In some cases, these incidents involve people being injured or killed due to the release of radioactive contamination. Most incidents involve accidental releases that have caused contamination, but had no other immediate effects. Some incidents only had the potential to release radioactive material, and are included because of the tensions such incidents caused (collisions between nuclear-powered submarines, for instance). Due to government secrecy, it is difficult to determine with certainty the extent of some events listed below or, occasionally, whether they happened at all.

First notice of radioactivity in the fallout was raised seven hours after the detonation when fallout reached Rongerik atoll. A group of 28 service members working at the weather station on Rongerik, 160 miles (260 km) east of Bikini, began evacuating about 30 hours after the explosion.


The accident was discovered by those outside the reactor building when radiation and thermal alarms alerted fire crews and health physicists, who discovered radiation levels exceeding 200 mR/h hundreds of feet from the reactor building. Emergency crews were at first unable to find either a fire or the workers, but encountered radiation levels as high as 1000 mR/h inside the reactor building. One of the three workers was removed from the building but died a few hours later. The other two bodies remained in the building for several days while hundreds of rescue workers initiated recovery operations. Of those recovery personnel, 22 received radiation exposures in the range of 3 rem to 27 rem, according to 1961 Atomic Energy Commission reports. The reactor was dismantled and the 13-ton core and pressure vessel was removed several months later.
