This report presents the results of measurements of ambient outdoor radon concentrations around the Grand Junction, Colorado, uranium mill tailings pile during the period of April 27, 1974 to April 2, 1975. A similar study was done by the U.S. Public Health Service in 1967 and 1968 before the pile was stabilized, and this study was done after the pile was stabilized to determine the effects of stabilization. Air samples were collected over a 48-hour period in a Mylar bag which was sent to the laboratory for radon analysis, using alpha scintillation cells. Samples were collected at each of 20 stations every three weeks for one year. The samples collected on the pile had higher radon concentrations following stabilization, and the exact cause for this is not known. Radon concentrations in the predominant daytime wind direction had elevated radon concentrations which are a power function with distance. Samples collected in other directions away from the pile contained background concentrations of radon.
