Which is an example of a high-energy radiation source used in industrial radiography?

Cobalt-60 is recognized as a high-energy radiation source commonly utilized in industrial radiography. This isotope emits gamma rays with significant energy, which is essential for penetrating dense materials and providing high-quality images for non-destructive testing. The gamma rays produced by Cobalt-60 have the ability to penetrate through objects, making them ideal for examining structural integrity and identifying flaws within various components.

In the context of industrial radiography, the effectiveness of a radiation source is often measured by its energy and penetrating power, with Cobalt-60 standing out due to its high-energy emissions. The gamma rays from Cobalt-60 are typically in the range of 1.17 and 1.33 MeV, which is well-suited for inspecting thick metal structures or welds.

Other isotopes mentioned, such as Cesium-137, Barium-133, and Xenon-133, do not possess the same level of energy or effectiveness in industrial applications. Cesium-137 is primarily used in radiation therapy and medical applications. Barium-133 and Xenon-133 are less commonly applied in a radiographic context, focusing more on specialized medical imaging rather than providing the robust penetration capabilities required for industrial applications. Thus, Cobalt-60 remains
