How were sites chosen to represent background for radiation in soils?
There are two sites chosen for this purpose – the National Guard Training Site and the Lew-Port School property. They were chosen because records indicate that no radiological activities have taken place in the survey areas. According to Corps health physicists, radiation levels observed were typical for regional geology and for types of surfaces surveyed (soil, concrete, and gravel). During the Remedial Investigation, the Corps took many background samples on and around the LOOW and NFSS properties. Back 5. If the Corps is not authorized to answer questions about health risks, then why did the Corps present results of the gamma walkover at the Lewiston-Porter school and say that no hazard to the public was found? A risk assessment is a little different than a public health assessment (study). The risk assessments that the Corps conducts at DERP-FUDS and FUSRAP sites, such as LOOW and NFSS, follow the USEPA’s Risk Assessment Guidance for Superfund sites. The Corps is responsible for de
