Dirty bomb


  • Also known as "Radiological Dispersal Device"[1]
  • Consists of radioactive material packaged into non-nuclear (conventional) bomb[1]
    • No nuclear fusion/fission occurs
    • Detonation causes injuries from conventional explosion and also spreads radioactive material, causing radiation injuries and cancer
    • Radioactive material spread locally via blast, and carried more distantly via aerosolized or particulate "plumes"
    • Multiple radioisotopes from various sources (e.g. nuclear fuel waste, medical radiography, etc) could be employed
  • Most injuries and deaths will be caused by blast injuries, not radiation injury[2]
  • Triage of patients by radiation dose received is important and should be coordinated with disaster response officials.
