Officials say they'll be distributing free potassium iodide tablets to Delaware residents who live within 10 miles of the Salem/Hope Creek nuclear power plant in New Jersey.
The tablets will be distributed July 31 and Aug. 28 at two locations in Middleton.
Officials say the tablets can protect the thyroid gland from radioactive iodine, which a plant may release in an emergency.
Evacuation is the primary way Delaware residents would get out of harm's way in an emergency, but the tablets offer additional protection.
If a radiation emergency were to occur, officials would inform the public through the use of emergency alert system radio stations. The information would include evacuation instructions as well as instructions on when to take the potassium iodide tablets.
