The Space Sciences Laboratory (SSL) at UC Berkeley is a preeminent university lab for space research and has participated in 50+ NASA missions since 1959.
John Tomsick, PI of NASA's COSI mission, describes the practical applications resulting from gamma ray detectors. From PET scans to radiation monitoring to protecting astronauts, Compton imaging technology has a profound impact on our health and safety.
