Weldon Spring Site. Annual site environmental monitoring report, calendar year 1985. Surplus Facilities Management Program (SFMP)

The monitoring program at the WSS measures uranium, /sup 226/Ra, and /sup 230/Th concentrations in surface water, groundwater, and sediment; radon gas concentrations in air; and external gamma radiation exposure rates. Potential radiation doses to the public are also calculated. During 1985, annual average radon concentrations at the WSS ranged from 3 to 43% of the DOE limit for uncontrolled areas. The highest measured external dose rate was 50 mrem/yr above natural background. The measured background dose rate for the WSS area is 99 mrem/yr. The WSS was formerly used for the processing of radioactive materials. Radioactivity above currently applicable limits exists at the site, and elevated levels of radiation will be present until remedial action is completed. Radon concentrations, external dose rates, and radionuclide concentrations in groundwater and surface water at the site were generally equivalent to 1984 levels. The calculated radiation dose to the maximally exposed individual at the Weldon Spring Raffinate Pits/Weldon Spring Chemical Plant was 0.2 mrem, which is <1% of the radiation protection standard. The calculated radiation dose to the maximally exposed individual at the Weldon Spring Quarry was 0.9 mrem, which is also <1% of the radiation protection standard.
