The study of interaction of photons with matter finds
wide application in areas such as industry, medical
radiation dosimetry and radiation shielding. A careful review of these measurements indicates that
the studies are exhaustive in respect of pure elements.
However, measurements on photon attenuation in alloys
are meagre. This is mainly due to the difficulty in
procuring targets in suitable form for experimentation.
Such studies play a prominent role in selecting
alternative shielding materials on the cost-effective basis.
