Free Potassium Iodide tables to be distributed in Dauphin County

This is an archived article and the information in the article may be outdated. Please look at the time stamp on the story to see when it was last updated.

      Pennsylvanians who live, work or attend school within a 10-mile radius of the state’s five nuclear power plants, including the Three Mile Island Nuclear Generating Station (TMI), can acquire free potassium iodide, or KI, tablets from the state Department of Health on August 8.

When taken as directed, KI helps protect the thyroid gland against harmful radioactive iodine that may be released during a radiological emergency. Because not all radiological releases involve radioactive iodine, no one should take KI tablets unless directed to do so by state health officials or the governor.

Four 65-milligram tablets will be provided to each person. Individuals can pick up KI tablets for other family members or those who are unable to pick them up on their own.  Directions on how to store the tablets and when to take them will also be provided at each location.

Anyone can take the tablets, unless they are allergic to KI.  They are safe for pregnant women, women who are breastfeeding, people on thyroid medicine, children and infants.  Individuals who are unsure if they should take KI should ask a health care provider.

KI tablets are also available throughout the year at county and municipal health departments or state health centers.

KI tablets will be available between 2 p.m. and 7 p.m. on August 8 at the following distribution sites in Dauphin County:

  • Hummelstown Fire Hall, 249 E. Main St., Hummelstown
  • Londonderry Township Building, 783 S. Geyers Church Road, Middletown

No appointments are necessary.

    Yay! But why are these necessary to distribute now? Food and blankets are distributed when the are needed. Shelters open for heat waves and cold snaps when they are needed. Sounds like a total waste of money. What's the shelf life of the pills? There hasn't been an emergency in 34.5 years.
