Selenium-75

Selenium-75 sources are available in cylindrical and quasi-spherical focals, permitting shorter SFDs and greater sensitivity on fixed geometries.
  • Ideal for controlling the size of the exclusion zone during radiographic exposures at congested work sites
  • Optimizes image contrast on radiographic films while lower energy photons provide a better response on storage phosphor plates
  • Provides the needed accessibility in fabrications that x-ray generators cannot access
APPLICATIONS
  • Off shore oil rigs and outages at power generation plants where exposure to non-occupational workers (members of the public) is a problem
  • Self propelled pipeline crawlers (QSA Global, Inc. Model 979) and directional ...
