Abstract
This disclosure pertains to a gamma radiation source, including enriched Iridium-191 and Boron-11. Some embodiments may include alloying. Some embodiments may include sintering. The resulting disk, adapted for radiological sources, typically has a reduced attenuation and a reduced cost, due to the reduction in the use of Iridium-191. Substitutes for boron include aluminum, silicon, vanadium, titanium, nickel, platinum, phosphorus and/or combinations thereof.
