Abstract
The potential for using highly penetrating radiation for processing bulk material is examined. It is found that gamma radiation, which is highly penetrating and nonactivating, is an acceptable radiation source but that only very low numbers of atomic interactions are possible even with intense sources. This limits the usefulness to certain classes of processing. The most promising of these are ones where undersized solute atoms are preferentially displaced and concentrate at interfacial sinks. The possibility for radiation-assisted nucleation is also examined, as are source type, strength, and handling limitations.
