In support of the DTRA-NTD sponsored Quantification and Swarm projects, LBNL participated in a measurement campaign in collaboration with Idaho National Laboratory and the Nuclear Science Center at Washington State University. At this campaign, WSU irradiated copper in their nuclear reactor to create Cu-64, which was packaged into 100 easily handled sealed radioactive sources. Cu-64 is a convenient isotope because its 12.7 hour half-life renders it safe after a few weeks. These sources were placed on a rugby practice field in predetermined configurations and measured by handheld, vehicle-borne, and UAS-carried LAMP systems. The images below describe a preliminary result from a UAS-borne MiniPRISM LAMP survey of a modified square configuration where the bottom-right section of the square had its radioactive material translated to the top-left, forming a hotspot and coldspot. Below that are photographs of our source placement grid and an airborne photograph of our gridding.
