TRANSMISSION OF GAMMA RADIATION THROUGH THIN, FINITE SLABS,
Abstract
The shielding of gamma radiation -- at photon energies where the Compton scatter process is dominant -- results in a transmitted beam that is largely composed of scattered photons. An approximate formula was developed through experiment to calculate the scattered radiation and therefore determine the exact transmission, i.e., dose build-up factor (B), for thin shields in the range of photon energies from 0.6 to 2 MeV. The results of the experiment also gave rise to a simple method of measuring any microscopic scattering cross section by an array of detectors without loss of the definition of the scattering angle.
