Connecticut Department of Emergency Services and Public Protection Radiological Emergency Preparedness webpage, has public information available at:

KI Tablets/Potassium Iodide
Potassium iodide, also known as KI, is a form of iodine. KI helps protect your thyroid gland when there is a chance you might be exposed to a harmful amount of radioactive iodine. Taking KI saturates the thyroid with harmless iodine and prevents radioactive iodine from being absorbed.

The State of Connecticut makes potassium iodide tablets available to residents and workers within the 10-mile emergency planning zone (EPZ) around Millstone Power Station in Waterford, Connecticut. The affected communities include: East Lyme, Old Lyme, Waterford, New London, Groton City, Groton Town, Fishers Island, NY, and portions of Lyme, Montville, Ledyard.

If advised to “Take Shelter”, the Connecticut Department of Emergency Services recommends:

If you are located in an area that has been advised to “Evacuate”, please be aware that state and local plans were developed and are in place to assure your safety. Each community within the 10-mile radius of the nuclear power facility has been assigned to one of five Connecticut communities predesignated as a Host Community. These Host Communities have agreed to receive and shelter individuals who have been told to evacuate their homes or the area. When directed to evacuate, please carry out the following:

Evacuation Routes

All Towns:  In general, if an evacuation is ordered for any town, the evacuation routes and destinations will be broadcast via the emergency broadcast system. If you know of neighbors or co-workers with language or hearing difficulties please inform them of any evacuation information that you hear from an emergency broadcasting system.
