摘要： Disclosed example gamma radiography sources include an encapsulated quantity of at least 10 Ci of Hafnium-175 (Hf-175). Disclosed example gamma radiation exposure devices include: a gamma radiation source comprising a quantity of Hf-175; and a shielding device configured to attenuate gamma radiation emitted by the gamma radiation source while the gamma radiation source is in a stored position, and configured to allow the gamma radiation source to be moved to an exposed position for gamma radiation exposure.

摘要： The disclosure pertains to a radiation source, such as an active insert, typically containing porous or microporous iridium or compounds, alloys or composites thereof within an encapsulation, and methods of manufacture thereof. The porosity or microporosity or low-density alloying ingredient with iridium causes a reduced density of the iridium within the active insert to be achieved.

摘要： A neutron sealed source holds cermet wire sources, such as Californium-252/Palladium wires, in separate blind apertures within a stainless steel block. The stainless steel block is part of an inner encapsulation and includes blind apertures arranged in rotational symmetry for receiving the cermet wire sources. The cermet wire sources are separated from each other and the fission and decay heat is rejected through the stainless steel block.

摘要： 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.
