SCDHEC Fukushima Information
SCDHEC Information and Response to Fukushima Daiichi
Amid continued concerns over radiation and nuclear issues in Japan, SCDHEC has provided this document Radiation Information PDF to give insight into nuclear power plant operations and radiation topics here in South Carolina. The document includes the most frequently asked questions and answers in:
- South Carolina Radiation History/Overview
- Radiation Basics
- Radiation Health
- How Nuclear Power Plants Work
Final Assesments on SCDHEC testing: (May 2011)
Most recent DHEC lab tests show no detectable Iodine-131 in drinking water samples, due to the Japan nuclear emergency
The S.C. Department of Health and Environmental Control laboratory tests confirm Iodine-131 has not impacted drinking water supplies. Drinking water samples collected from Columbia, Jenkinsville, Seneca and Barnwell water systems showed no detectable levels of Iodine-131 in the drinking water systems due to the events at the Japanese nuclear power plant. Minor levels of Iodine-131 have been detected in several air and rain water samples from around the state.
At this time, there are no protective measures recommended for South Carolina residents including the use of Potassium Iodide.

Initial Advisory: (March 2011)
SCDHEC finds minor levels of Iodine-131 in air and rainwater, due the Japan Nuclear Emergency, however levels do not cause a health concern or health threat. (04/01/2011)
Results from SCDHEC lab analysis has confirmed minor levels of Iodine-131 in air and rainwater samples collected from several locations throughout the state. Air monitoring has been conducted in Rock Hill, Seneca, Jenkinsville, Hartsville and Columbia areas.
The rainwater samples have been collected from the Jenkinsville, Rock Hill, and Columbia area.
These findings are in line with federal U.S. Environmental Protection Agency findings throughout the region and the country. It is believed that the source of the elevated levels is the on-going incident in Japan.
The levels detected are low enough that there would be no significant health concern or health threat. The levels we are seeing coming from Japan are 100,000 times lower than what you would get from taking a roundtrip international flight
SCDHEC personnel continue to collect air and precipitation samples from multiple locations throughout the state and will continue to submit them to the SCDHEC state laboratory for analysis.
Drinking water samples are have been collected from Barnwell, Seneca, Columbia and Jenkinsville areas and sent to the DHEC state laboratory and USEPA for analysis. At this time, there are no protective measures recommended for South Carolina residents including the use of Potassium Iodide.
