A collimated gamma ray beam consists of equal numbers

Reference no: EM13548296

A collimated gamma ray beam consists of equal numbers of 0.1 MeV and 1.0 MeV photons. If the beam enters a 5 cm thick lead shield, what is the relative portion of 1 MeV photons to 0.1 MeV photons in the emergent beam? State the source of all values used & show your work.
