Columbia, South Carolina – Rising global tensions and recent strikes involving nuclear-linked infrastructure are prompting renewed attention across South Carolina, one of the most nuclear-dense states in the country with four active power stations.
According to the U.S. Food and Drug Administration and South Carolina Emergency Management Division guidance, potassium iodide, or KI, can help protect the thyroid from radioactive iodine if taken at the right time. A recent ballistic missile strike on a nuclear-related facility in Iran did not result in radiation release, but officials say it highlights how quickly situations involving nuclear infrastructure can escalate.
South Carolina is home to the Oconee Nuclear Station in the Upstate, Catawba Nuclear Station near the North Carolina border, V.C. Summer Nuclear Station in Fairfield County, and the H.B. Robinson plant near Hartsville. Major population centers including Columbia, Charleston and Greenville could fall within impact zones depending on wind direction and incident scale.
KI works by saturating the thyroid with stable iodine, reducing the body’s ability to absorb radioactive iodine during exposure. That protection is most effective if taken shortly before or immediately after exposure, with effectiveness dropping after several hours. It only protects the thyroid and does not shield other organs or reverse existing damage.
Communities across the Midlands, Upstate and Pee Dee regions are part of emergency planning considerations tied to these facilities, with broader impacts possible under certain conditions.
Emergency officials stress evacuation or sheltering in place remains the primary protection strategy. KI is considered a secondary layer of defense and should only be taken when directed by public health authorities.
Iodine is also safely used in controlled medical treatments for thyroid conditions, demonstrating its targeted effectiveness when properly administered.
Residents are encouraged to review emergency plans and consider access to KI tablets now, as guidance could be issued rapidly during any nuclear-related emergency.
