] 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 and business secrecy, it is difficult to
] determine with certainty the extent of some events listed
] below or, occasionally, whether they happened at all.
