Surface radiation survey for the Phase 1 remedial investigation of the 300-FF-1 operable unit on the Hanford Site
This report summarizes Task 3a-1 of the Phase I Remedial Investigation for the 300-FF-1 Operable Unit on the Hanford Site, near Richland, Washington. The purpose of the Remedial Investigation is to determine the nature and extent of the risk presented by releases of hazardous substances from the operable unit. The purpose of Task 3a-1 was to locate any areas of contaminated soil outside of operable unit waste facility boundaries. Surface radiation survey and sampling activities in the 300-FF-1 Operable Unit were conducted from September 1989 to December 1989 and April 1990 to June 1990. Surveys were conducted primarily using portable Geiger-Muller beta/gamma detectors. As a result, 77 locations were found where radiation occurred above a statistically calculated background estimate. The Ultra Sonic Ranging and Data System (USRADS) was also used to survey a limited area. Analysis of the USRADS data revealed several elevated measurements that were not detected at the same locations with the Geiger-Muller detector. 6 refs., 14 figs., 4 tabs.
