Radiological Atmospheric Monitoring Adjacent to SRS

Radiological airborne contaminants can affect the public through exposures from accidental releases. ESOP’s Radiological Atmospheric Monitoring sites are located to provide spatial coverage of the project area where public exposure could occur. Air monitoring capabilities include operating and maintaining air monitoring stations with the capacity for sample collection using glass fiber filters, rain pans, silica gel columns, and thermoluminescent dosimeters (TLDs). The glass fiber filters are used to collect total airborne particulates. Particulates are screened weekly for gross alpha and gross beta emitting radionuclides. Glass fiber filters are composited annually and analyzed for selected isotopes. Precipitation is collected monthly for tritium analysis. Silica gel distillates of atmospheric moisture are analyzed monthly for tritium. All tritium analyses are performed at the SCDHEC Region 5 EQC Tritium Laboratory. TLDs are collected and analyzed quarterly for ambient beta-gamma levels.
