Comparative levels of radioactive air pollutants from industry and fallout. A progress report of radioecological investigations of airborne radioactivity in the Utah environment. [1971 and first two months of 1972]
Results are reported of measurements carried on during the year 1971 and the first two months of 1972 on the radioactivity from natural as compared to artificial radiation sources in the environment in Utah. During this time, a major portion of our work was devoted to analyses of the data and preparation of a report related to the Baneberry venting event and the accumulation of data on fallout from the January 7, 1972 Chinese nuclear explosion. Calibration procedures were developed for air samplers for the establishment of the numbers of pCi/m/sup 3/ in air. The responses of the air monitors in relationship to the ventilation index, seasonal effect, and the industrial complexity of the area were analyzed. Continuous measurements were made of the levels of radioactive materials in soils and vegetation and the results of these studies are presented mainly in tabular form. Comparisons have been made of the levels of radioactive materials in soils on the basis of square mile levels and the distribution of the radioactive materials in the soil profiles. Measurements of farm crops, including the major sources from which dairy products would be produced, have been made, and some comparisons by year and location have been made. Studies of secondary aerosols have been made using the dust accumulated on farm implements as the indicator of the kinds of secondary aerosols to which farmers and outdoorsmen might be exposed. These results would also be indicative of the kinds of dusts produced when high winds resuspend soil deposited radionuclides.
