A Bayesian approach to free-moving radiation mapping with a single detector
Large-area radiation imaging is crucial in enhancing nuclear safety and security. Traditional mapping methods involve stationary gamma-ray detectors or imagers and necessitate multiple time-consuming static measurements at various locations.

Lei Pan received the 2023 Best Paper Award titled, “Performance of Perovskite CsPbBr3 Single Crystal Detector for Gamma-Ray Detection”.
Room temperature gamma ray detectors are the cornerstone of many radiation detection and imaging systems in various fields, such as medical imaging, nuclear security, scientific research and so on. Compared to scintillators, the semiconductor gamma ray detector has the advantage of intrinsically high energy and spatial resolution. However, after decades’ research and development of various candidate semiconductors, CdZnTe is the only commercial semiconductor gamma ray detector.

Making Rad Maps With Robot Dogs
In 2013, researchers carried a Microsoft Kinect camera through houses in Japan’s Fukushima Prefecture. The device’s infrared light traced the contours of the buildings, making a rough 3D map. On top of this, the team layered information from an early version of a hand-held gamma-ray imager, displaying the otherwise invisible nuclear radiation from the Fukushima…

Semiconductor Detector Lab Reaches for the Stars
For decades, the LBNL Semiconductor Detector Lab (SDL) has been at the forefront of advancements in gamma-ray detector technology. Amongst the technologies pioneered at the SDL are double-sided high-purity germanium (HPGe) strip detectors with amorphous germanium (a-Ge) contacts [1] (Fig. 1). These devices find application in a range of areas including basic science, nuclear security,…

Applied Nuclear Physics Program Aiding Clean-up of Cold War-Era Radioactive Contamination through Radiological Mapping
From 1955–1988, low-level waste solutions from the processing of uranium and irradiated nuclear fuel were discharged into unlined earthen storage basins at the Savannah River Site (SRS) F-Area [1]. Over the decades, radioactive contaminants including uranium and iodine-129 (I-129) have leaked out of the basins and into the groundwater of the surrounding wetlands, and are…
