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.
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 beam exposure devices used to perform panoramic exposures of pipelines with inner diameters down to three inches (77 mm)
