Abstract : At the request of the U.S. Air Force Radioisotope Committee Secretariat, the U.S. Air Force School of Aerospace Medicine, Consultative Services Division (USAFSAM/OEC), Radiation Health Consulting Branch performed an independent radiological verification survey of five areas, consisting of 25 survey units within AOC 314, located on the former McClellan AFB, California, from 14-17 October 2014. USAFSAM/OEC personnel performed a gamma walkover survey of the five areas to assess the feasibility of unrestricted release and ensure the potential health risk to future inhabitants is minimized. USAFSAM/OEC personnel also collected 22 soil samples from within AOC 314. Laboratory analysis revealed that the concentration of radium-226 (Ra-226) in 10 of the soil samples exceeded the cleanup goal of 2.0 pCi/g agreed upon between the USAF and the State of California. Four of the five areas within AOC 314 yielded at least one sample that exceeded 2.0 pCi/g. The highest concentration of Ra-226 found in any of the soil samples was 25.8 pCi/g. Based on these findings, the cleanup goal was not met, and further remediation should be accomplished to ensure that the potential health risk to future inhabitants is minimized and cleanup levels are within current guidelines.
