Abstract
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.
