(2) only naturally occurring radionuclides were identified in the gamma spectral analyses(1)
(3) the ambient gamma radiation measurements indicate that the average annual gamma exposure is similar at all three monitoring stations and periodic intervals of increased gamma values appear to be associated with storm fronts passing through the area(1)

and dust conditions at stations installed adjacent to clean slate i and clean slate iii and at the ttr range operations control center. the primary objective of the monitoring effort is to determine if winds blowing across the clean slate sites are transporting particles of radionuclide-contaminated soils beyond both the physical and administrative boundaries of the sites. results for the calendar year (cy) 2013 monitoring include: (1) the gross alpha and gross beta values from the monitoring stations are approximately equivalent to the highest values observed during the cy2012 reporting at the surrounding community environmental monitoring program (cemp) stations (this was the latest documented data available at the time of this writing)(1)

differences in the observed dust concentrations are likely due to differences in the soil characteristics immediately adjacent to the monitoring stations. neither the resuspended particulate radiological analyses nor the ambient gamma radiation measurements suggest wind transport of radionuclide-contaminated soils.(1)

radiological contaminants may be entrained with the soil particles and estimate their concentrations.(1)
