Application of FLUKA code to gamma-ray attenuation. energy deposition and dose calculations

摘要

Background: In radiation therapy, water is the phantom material of choice, both for reference and for relative dosimetry measurements. Solid phantoms, however, are more useful for routine measurements because they tend to be more robust and easier to set up than water phantoms. Materials and Methods: FLUKA input data cards have been arranged in sequential order. A simple cylindrical geometry with the axis along the z-direction was described in the input file. A beam of lxlO5 gamma-rays was directed towards the materials in the z-direction.
