Özet

This study was carried out to determine some distinctive features of thermoplastic materials used in radiotherapy. In this work, effective atomic numbers and number, energy and dose albedos of different colored thermoplastic samples (white, light green, green and blue) were determined for 59.54 keV gamma rays by using a high purity germanium detector. It is observed that the white thermoplastic sample has good reflectivity for gamma rays. The blue thermoplastic sample indicates superior shielding quantities since it has the lowest values of number, energy and dose albedos.
