This is a listing of criminal acts resulting in acute radiation casualties. It is a subset of the Database of Radiological Incidents and Related Events. Links in the table are to more detailed incident summaries.

The 28 events below include:

• 9 assaults targeting individuals;
• 8 incidents involving thefts of radioactive sources;
• 5 intentional self-exposures;
• 1 apparent act of sabotage of a research reactor;
• 5 unspecified criminal acts.

Notes on table:

• code: coding for type of accident. See this page for list of codes.
• highest dose: highest dose to any individual; in cases of more than one casualty, most doses were significantly lower. "L" indicates casualties involving localized exposures. "N" indicates the individual(s) receiving the highest dose died from effects other than ionizing radiation.
• deaths: figures are for ionizing radiation-induced deaths only; parenthetical figures include those from other effects (e.g. thermal and mechanical results of explosions).
• public: codes indicating case involved known exposure to the public (i.e. non-employees). See this page for list of codes.
• source: radioisotope involved, if known. See this page for list of codes.
• release: radioactive release into the environment, if any; for point events (e.g. criticality accidents or nuclear detonations), activity is for 1 hour after event.
