Quantity and Quality of Scattered X Rays

Abstract

The paper presents measurements of the amount and quality of radiation scattered from materials of different atomic numbers. At all energies of the primary X-ray beam used, low atomic number materials scatter the greatest quantity of radiation, the differences in the normal deep therapy range being large. The quality of the radiation scattered shows a maximum for scatterers of medium atomic number in this energy range and a steady increase with atomic number at the highest energy used.
