Apart from Potassium Iodide (KI) to keep the thyroid gland from absorbing radioactive iodine which may prevent thyroid cancer from developing in the futre, treating radiation exposure may include IV fluids for hydration; standard burn skin care; wounds gently washed to prevent internal contamination; emergency management of nausea and vomiting with antiemetics (antinausea medicine); management of pain with morphine or acetaminophen (aspirin will interfere with blood clotting and make bleeding worse); antibiotics (recommended only if an infection takes hold); blood transfusions; blood-cell growth stimulants if necessary for patients whose bone marrow is affected, which are most effective when given soon after exposure; bone-marrow transplantation, but it remains a controversial treatment; probiotics, which involve the use of bacterial implantation to recolonize the body's natural store of bacteria in the gastrointestinal tract, which we use to digest and absorb food; and chelating agents such as DTPA (the calcium form is used for early decontamination and the zinc form is used for long-term treatment).
