Potassium Iodide (KI) Distribution

Potassium Iodide (KI) Distribution


As part of Montgomery County’s continuing emergency preparedness effort, we continue to make available free potassium iodide tablets (KI) to Montgomery County residents who live, work and/or attend schools within a 10-mile radius of the Limerick Nuclear Power Plant.

KI tablets can be picked up daily, Monday-Friday, 8:00am to 4:00pm, at the Pottstown Health Center, 364 King Street, Pottstown, PA. Residents can also call Pottstown Health Center's phone number (610-970-5040) anytime of the year to inquire about the KI Tablets.
Potassium iodide, or KI, can help protect the thyroid gland against harmful radioactive iodine when taken as directed during radiological emergencies. Individuals should only take KI when told to do so by state health officials or the governor.

Adults and children will receive a two-day supply of KI. Directions detailing when and how to take the tablets, as well as instructions for proper storage, will be provided with the KI tablets. Individuals can pick up KI tablets for other families or those who are unable to pick them up on their own.  

Know What to Do in Case of a Nuclear Accident


Radioactive iodine, one of the contaminants that could be released in a nuclear accident or similar event, can increase the risk of thyroid cancer. Potassium iodide (KI) is a drug that, when taken in an appropriate and timely dosage, can block exposure to radioactive iodine.

As part of Montgomery County’s continuing emergency preparedness efforts, the Montgomery County Health Department is again making potassium iodide tablets available to residents who live or work within a 10-mile radius of the Limerick Nuclear Power Plant.

Public Form (Within a 10 mile radius)


Montgomery County residents can complete the KI Public Form online, print the form, and bring it with them to the Pottstown Health Center to help expedite the process. If forms cannot be printed, they will be available at the distribution sites.

Business Form (Within a 10 mile radius)


Unlike families, businesses are given a one day supply of KI. Businesses should call the Pottstown Health Center (610-970-5040), to provide information on the number of employees, and to schedule a pickup time for their KI tablets. To expedite the process, businesses can complete the KI Business Form and email the form to the Montgomery County Health Department. Business KI orders will not be filled at the public distribution sites. Businesses will be contacted when the order is ready for pickup at the Pottstown Health Center.
