The Integral Fast Reactor's fuel cycle is the first one capable of taking actinides such as neptunium, americium, and plutonium and automatically putting them back--integrating them quickly and automatically--into the nuclear fuel stream.
Industrial gauges usually contain [137cesium, 60 cobalt, 26 radium or 241 americium, each of which could be harmful in the event of protracted exposure, with the latter two being of a more serious nature.
