Background
- Non-nuclear (conventional) bomb cased in radioactive material
- can cause exposure to I-131
- administration of potassium iodide (KI) can significantly reduce thyroid I-131 uptake, which can later causes thyroid cancer
- for persons older than 40 years of age, the risk for radiation-induced thyroid cancer is extremely low, while the potential side effects of prophylaxis due to preexisting thyroid disease tend to increase

Treatment
Treatment with stable iodine when the committed dose equivalent to the adult thyroid is expected to exceed 250 milliSieverts (mSv), the equivalent of 25 rem (FDA 2001).
- Under 40 years old
- potassium iodide (KI)
- immediate and Qday x 7-14 days
- Over 40 years old
- no KI treatment
- contraindication = iodine allergy
- potassium iodate (KIO3) can also be used (more GI irritation)
