Improved reconstruction of Cs contamination distribution in Fukushima measured with High-Efficiency Multimode Imager HEMI on board JAEA’s RMAX unmanned helicopter

In May 2014, a team from LBNL traveled to Fukushima, Japan to perform demonstration measurements for mapping Cesium contamination. In collaboration with the JAEA and University of Tokyo, our High Efficiency Multi-mode Imager (HEMI) was attached to an unmanned RMAX helicopter. HEMI is a Compton gamma-ray camera and thus measures the direction of the gamma-rays, […]

Flights of compact unmanned aerial vehicle continue – soon with radiation sensors

In the Applied Nuclear Physics group we are developing a sensor package to be flown on a small quadcopter. This package will combine a gamma-ray detector with a visual camera and GPS. Having all of these sensors allows us to create accurate activity maps by performing data fusion. This will allows us to create high […]

Successful demonstration of real-time Scene Data Fusion or 3D Volumetric Imaging with hand-portable High-Efficiency Multimode Imager HEMI

Recently we have demonstrated real-time Scene Data Fusion of visual information and gamma-ray sources with a high degree of accuracy, in 3-D[cite ross’s paper]. For that work, we utilized a cart based Compton camera system. We have recently adapted this method with our High Efficiency Multi-mode Imager (HEMI) which is a hand-held Compton gamma-ray camera. […]

DoseNet preparing to go online

RadWatch is now ready to expand by taking our efforts to reach out to the public into the classroom. The DoseNet project aims to put networked dosimeter devices in schools around the Bay Area and eventually beyond. This will give both the public and the students access to real world data showing how levels of […]
