Abstract
The disclosure pertains to improvements in a gamma radiation source, typically containing low-density alloys or compounds or composites of iridium in mechanically deformable and compressible configurations, within an encapsulation, and methods of manufacture thereof.
Claims5
A radiation source including a stack of disks containing iridium or an iridium alloy of 100 percent density wherein the stack contains spaces between adjacent disks thereby reducing the average stack density in the range 30-85% of the density of 100% dense pure iridium wherein the disk stack is subsequently compressed, deformed or worked after irradiation to form a quasi-spherical shape inside a source capsule.
