Masters Theses

"Gamma-ray number, energy and dose albedo are calculated with the Monte Carlo technique. A plane monoenergetic beam was considered at normal incidence upon single material shields at initial gamma energy up to 10 MeV. Aluminum, iron and lead are used as shield material. The contribution of secondary photons which are produced as a result of various photon interactions in the shield are taken into account. These secondary photons are annihilation gammas, X rays and bremsstrahlung gammas. In certain cases, they constitute a considerable fraction of the reflected radiation.

Annihilation gammas predominate in the reflected radiation for all energies above 1.02 …
