Radiological contamination penetration depth in Fernald transite panels

PDF Version Also Available for Download.

Description

To characterize the penetration depth of radiological contamination through the thickness of transite (an asbestos-cement building material) from the Department of Energy (DOE) Fernald site, both destructive and non-destructive analysis techniques were used. The destructive techniques were based on progressively removing layers of material and subsequent direct analysis of successive surfaces. These laminar analyses included quantitative measurements using a Geiger-Mueller (G-M) detector and qualitative measurements based on autoradiography and ultraviolet photography. G-M detector measurements during layer removal provided quantitative distributions consistent with diffusion theory and have served to validate a novel non-destructive technique. The ultraviolet analysis provided qualitative information with ... continued below

Description

To characterize the penetration depth of radiological contamination through the thickness of transite (an asbestos-cement building material) from the Department of Energy (DOE) Fernald site, both destructive and non-destructive analysis techniques were used. The destructive techniques were based on progressively removing layers of material and subsequent direct analysis of successive surfaces. These laminar analyses included quantitative measurements using a Geiger-Mueller (G-M) detector and qualitative measurements based on autoradiography and ultraviolet photography. G-M detector measurements during layer removal provided quantitative distributions consistent with diffusion theory and have served to validate a novel non-destructive technique. The ultraviolet analysis provided qualitative information with the advantage of instantaneous results that may be useful for screening samples. The autoradiographic analysis also provided qualitative results for comparison and image analysis. Both quantitative and qualitative results from this study indicated that the contamination did penetrate into the volume of the transite. However, this penetration depth was observed to be strongly dependent on the manner in which the transite was exposed to the contamination. Consequently, it is likely that significantly different penetration depths will be observed for different processes, buildings, and sites.
