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).
The active focal of the sources are octagon shaped in the range of 1.4 mm to 3.5 mm (maximum focal) to maximize the output in all directions of use while minimizing the focal spot size.
Sources are available in cylindrical and quasi-spherical focals. Compared to a right circular cylinder focal, the unique focal (quasi-spherical) of the Se-75 permits shorter SFDs and greater sensitivity on fixed geometries.
Testing of the metallic selenide sources demonstrates a high degree of thermal safety and material stability.
