This report presents the results of measurements of ambient outdoor radon concentrations and indoor radon progeny working level determinations during November 1975 for 10 locations throughout the Ambrosia Lake area and vicinity, New Mexico. For that portion of the study area in the vicinity of uranium mines and mills, statistical evaluation of the data indicates that ambient outdoor radon concentrations and the indoor radon progeny levels (WL) are in excess of typical background levels. Better definition of background levels and a more thorough evaluation of specific source terms in the immediate Ambrosia Lake area is strongly suggested. For locations in proximity to a uranium mill site, gamma radiation exposure rates and the radium-226 content of surface soils are also above normal background conditions. This may reflect the deposition of windblown tailings and/or ore dust. To assure compliance with State and Federal regulations, it is recommended that further studies be conducted over at least a one-year period for comparison to the applicable radiation protection guides for those areas in the vicinity of uranium mill sites. Radiation exposures to the general population occupying areas in the immediate vicinity of uranium mining and milling operations should also be evaluated.
