Radiation accidents and other events causing radiation casualties--tabulated data

compiled by Wm. Robert Johnston
last updated 20 January 2014

Notes and codes:

  • code: coding for type of accident. Codes:
    • A -- radiation accident (unspecified or other)
    • A-R -- accident involving nuclear reactor
    • A-NR -- accident involving naval reactor
    • A-PR -- accident involving power reactor
    • AC -- criticality accident
    • AC-RR -- criticality accident involving research reactor
    • A-a -- accelerator accident
    • A-d -- accidental dispersal of radioactive material
    • A-i -- accidental internal exposure to radioisotope
    • A-ir -- irradiator accident
    • A-mr -- medical radiotherapy accident
    • A-mx -- medical x-ray accident
    • A-os -- orphaned source accident
    • A-osd -- accidental dispersal of orphaned source
    • A-rg -- radiography accident
    • A-s -- accidental exposure to source
    • A-x -- x-ray accident
    • I-a -- intentional exposure of individual (assault)
    • I-c -- criminal act (unspecified)
    • I-s -- intentional self-exposure
    • I-t -- exposures resulting from theft of source
    • NT -- nuclear weapon test
    • NW -- combat use of nuclear weapon
  • highest dose: highest dose to any individual; in cases of more than one casualty, most doses were significantly lower. Codes:
    • L -- casualties involving localized exposures
    • N -- 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). Code:
    • F -- indicates fetal deaths.
  • public: codes indicating case involved known exposure to the public (i.e. non-employees). Codes:
    • c -- criminal acts in which only perpetrators were injured
    • m -- medical, exposure of patients
    • x -- exposures among public
  • source: radioisotope involved, if known. Codes:
    • * NW -- nuclear detonations
    • * -- criticality accidents
  • 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.
