English term or phrase:hard radiation
"Later that afternoon, an accident occurred with the demon core and its upper beryllium half fell, causing a "prompt critical" reaction and a burst of hard radiation. At the time, other scientists present observed the "blue glow" of air ionization and felt a thermal wave. Moreover, Slotin felt a sour taste in his mouth and a stinging burning sensation in one of his hands. Slotin instinctively jerked it upward, lifting the upper beryllium half and letting it fall, stopping the reaction."
