One objective of environmental monitoring and analysis at the Fernald Environmental Management Project (FEMP) is to determine whether {sup 222}Rn emitted from the K-65 silos following the bentonite sealant application has been reduced to a level such that the contribution from the K-65 silos to offsite background is less than 0.015 pCi/l at the location of the maximally exposed individual at a non-FEMP location. Because the annual average offsite environmental radon background concentration is 0.5 {plus_minus} 0.1 pCi/l,0 this low level {sup 222}Rn concentration can be determined only by modeling as monitoring techniques are not sufficiently precise to reliably detect such a small change. The flux of radon (pCi/M{sup 2}/sec) which is emitted from the silo dome by mechanisms of diffusion and air exchange will be calculated from the measured concentration of radon (pCi/M{sup 3}) in the dome headspace and will be used as the source term for the Gaussian plume model.
