Information on Potassium Iodide for Calvert Residents

If you live or work within 10 miles of the Calvert Cliffs Nuclear Power Plant you are eligible to receive Potassium Iodide (KI) tablets. KI helps protect the thyroid gland from damage caused by radioactive iodine that may be released from the plant during an emergency. KI does not protect any other part of the body from radiation damage. Therefore, KI is not a substitute for other protective actions such as evacuation or taking shelter, which protect the entire body. Should a radioactive emergency occur, official recommendations to the public for protective actions, including taking KI, will be broadcast by the media.

Heads of households or representatives from a business may come to the Health Department any Monday-Friday between 8:00 am – 4:00 pm to replace expiring tablets. We are encouraging family-run daycares, businesses and private residents to have KI on hand if they reside within the 10-mile “protective zone.”

If you live south of Prince Frederick you probably reside within the 10-mile protective zone. For specific details please go to the health department’s web page: Potassium Iodide Protective Areas Defined.

If you have any questions please call 410-535-5400, x334.
