Atlanta, Georgia – The difference between a basement and an upstairs room during a nuclear emergency could reduce radiation exposure by up to 90% in the first critical hours.
According to the U.S. Food and Drug Administration and Georgia Emergency Management and Homeland Security Agency, residents near Plant Vogtle near Waynesboro may be directed to shelter in place immediately if an incident occurs. That makes choosing the right location inside your home critical within minutes.
Basements offer the strongest protection because dense materials like soil and concrete block radioactive fallout. In parts of eastern and northern Georgia, including areas near Augusta and some suburban Atlanta communities, homes with basements provide a significant advantage during the early phase when radiation levels are highest.
However, many homes across southern and coastal Georgia, including Savannah and surrounding areas, are built on slabs without basements. In those cases, officials recommend moving to the most interior room possible—away from windows and exterior walls. Bathrooms, closets and central hallways can reduce exposure further, especially when surrounded by dense materials like books, water containers or furniture.
Upper floors and window-facing rooms should be avoided, particularly in multi-story homes and apartments where rooftop exposure can increase risk.
Potassium iodide, or KI tablets, may be recommended to protect the thyroid, but they do not shield the rest of the body. Shelter choice remains the most immediate and effective protection.
Emergency alerts could be issued with little warning. Identifying your safest indoor space now could make a measurable difference in how long you remain protected.
