Radiation injury

Morbus radiationis · Poškození zářením (nemoc z ozáření)

What it is

Ionising radiation kills the fastest-dividing cells first: marrow, gut, then skin.

Symptoms & signs

  • Nausea and vomiting within hours
  • marrow failure at 2–3 weeks
  • diarrhoea
  • skin burns
  • hair loss

🚩 Get help if…

  • call 112 / 911 now Vomiting within hours of a radiation exposure
  • call 112 / 911 now Bleeding, bruising or fever in the weeks after exposure
  • call 112 / 911 now Severe diarrhoea or confusion after exposure
  • see a doctor soon Red, blistering or peeling skin after exposure or radiotherapy

Where it strikes

Medical treatment

  • Decontamination
  • G-CSF
  • transfusion support
  • potassium iodide for radioiodine
  • antibiotics
  • stem-cell transplant in severe exposure

Natural & lifestyle

  • Distance, shielding, time
  • iodine prophylaxis where indicated
  • dosimetry monitoring

Emerging & experimental

  • Radiomitigators
  • regenerative marrow therapies

Alternative, off-label & anecdotal

Approaches used outside the guidelines, with what their supporters report and what testing has found so far.

  • Apple pectin for caesium after Chernobyl — small studies of faster clearance early / small studies
  • Iodised table salt instead of potassium iodide — far too little iodine, and dangerous amounts of salt not confirmed in trials
