Critical Pathways and Radiological Dose Assessment

ESOP uses the data from all environmental monitoring activities around the perimeter of SRS each year to calculate the potential radiation dose to the surrounding public within a 50-mile radius of the SRS center point.

Potential radionuclide dose or exposure to the public was calculated from radioactive concentrations that were identified in the environment, food and milk samples. A comparison of similar DHEC and SRS media resulted in an evaluation of both environmental programs based on averages and standard deviations.

Each year DHEC reviews the different inhalation, ingestion, and external exposure pathways that may result in a dose to the public. This identifies the possible routes of exposure and types of radiation that may contribute to an individual's radiation dose.
