selenium or iridium

Ndtmetal,
The answer to your question is it depends!
Image quality depends on a number of factors; pertinent to the isotope are energy level and source size.
Selenium is lower energy then Iridium, therefore the sensitivity would be better but the thickness of material which can be effectively radiographed is decreased.
The source size is dependent on the individual isotope with smaller sources producing better resolution.
You need to match the isotope to the application to produce the best radiograph possible.
