ESOP conducts radiological airborne sampling for contaminants that can affect the public through exposures from releases associated with SRS. We positioned radiological atmospheric monitoring sites (Ambient Air Monitoring locations) to provide spatial coverage where public exposure could occur.
Our monitoring capabilities include operating and maintaining eight air monitoring stations. These stations collect samples using glass fiber filters, rain pans, silica gel columns, and thermoluminescent dosimeters (TLDs).
The glass fiber filters collect total airborne particulates. We screen particulates weekly for gross alpha and gross beta emitting radionuclides. We composite glass fiber filters annually and analyze for selected isotopes.
Each month we collect precipitation from rain pans and silica gel distillates of atmospheric moisture and analyze each for tritium. Our local Tritium Laboratory performs the tritium analyses. We also collect our TLDs quarterly and they are analyzed by a contract laboratory for ambient beta-gamma levels.
