Abstract

The presence of radioactive contamination in soil presents significant challenges to monitoring for removable contamination. Implementing conventional removable contamination monitoring techniques (e.g., smear surveys) in Soil Contamination Areas (SCA) is not feasible. The measurement of contamination levels in the soil (on an activity per weight or volume basis) is relatively straightforward. It is difficult, however, to compare the results of such measurements to established posting and release values, which are provided in units of contamination levels per unit area. To ensure compliance with regulatory requirements, a study was performed on typical soil found in the Hanford Reactor liquid effluent sites. The study provided information used to determine the likelihood that radioactive contamination above posting and release values could be transferred from soil surfaces to surrounding areas, items, or individuals through contact or transport of soil from the work areas.
