Look and listen. Hughes Aircraft scientists show their miniature radiation detector. In top photo, one of them takes a close look at the heart of the new device—a thin wafer of highly pure silicon. When a charged particle strikes the silicon, it emits a pulse that can be measured and analyzed. In lower photo, Dr. S.S. Friedland listens to the response of a detector packaged in a cigarshaped tube with battery and amplifier. Hughes believes the detector will be useful in exploring space, in nuclear research, therapy, and industrial processing.
