“Trust, but verify.” Ronald Reagan’s famous dictum at the high point of the Cold War underscores the importance of what have become our most high-tech “eyes” in the nonproliferation mission to detect, interdict, and secure fissile and other radiological materials: cutting edge radiation detectors. Detectors enable discovery, and blend research with education.
