Real-time, meter-resolution gamma-ray mapping is relevant in the detectionand mapping of radiological materials, and for applications ranging fromnuclear decommissioning, waste management, and environmental remediation tohomeland security, emergency response, and international safeguards. We presentthe Localization and Mapping Platform (LAMP) as a modular, contextual andradiation detector sensor suite, which performs gamma-ray mapping in threedimensions (3-D) and in real time, onboard an unmanned aerial vehicle (UAV) orin a man-portable configuration. The deployment of an unmanned aerial system(UAS) for gamma-ray mapping can be advantageous, as the UAS provides a means ofmeasuring large areas efficiently and improving accessibility to someenvironments, such as multi-story structures. In addition, it is possible toincrease measurement robustness through autonomous navigation, and to reduceradiation exposure to users as a result of the remote measurement. LAMP enablesmeter-resolution gamma-ray mapping through Scene Data Fusion (SDF) [1], acapability that fuses radiation and scene data via voxelized 3-D MaximumLikelihood Expectation Maximization (MLEM) to produce 3-D maps of radioactivesource distributions in real-time. Results are computed onboard LAMP while itis flying on the UAV and streamed from the system to the user, who can view the3-D map on a tablet in real-time. We present results that demonstrate the SDFconcept, including a set of UAS flights where a 133Ba source is localized at atest site in Berkeley, CA and a handheld measurement in Fukushima Prefecture,Japan where the distribution of radiocesium(137,134Cs) released from theaccident of the Fukushima Daiichi Nuclear Power Plant is mapped. Thereconstruction parameters used for each measurement were identical, indicatingthat the same algorithm can be used for both point or distributed sources.
