Narrator: This is Science Today. An advanced radiation detection system has been developed at the Lawrence Livermore National Laboratory. It's called the Large Area Imager and according to John Valentine, the program leader of the Lab's Detection Technologies, it utilizes astrophysics technology.
Valentine: The Large Area Imager is based on coated aperture imaging, which has been used for many, many years in the astrophysics community, where you put a detection system on a satellite and are looking into space in order to try to image the point sources of light that are coming in there – there are gamma rays coming from stars, as well as light coming from them.
Narrator: In a terrestrial environment, this technology allows the detector to seek and find radiation sources with total insensitivity to variation in an area's radiation field, which can include naturally-occurring radioactive materials.
Valentine: The Large Area Imager has demonstrated detection at ranges approximately on the order of magnitude – a factor of ten larger distances than the commercially, off-the-shelf systems.
