Human body organs and tissue have different values of density. The nature of interaction between radiation and organs is not the same due to differences in density of medium, and energy and type of radiation. Low density medium has high range of energetic radiation inside the medium with low values of mass attenuation coefficient. Treatment plan considers the densities of human tissues and organs like water density, so readings of predicted doses inside body have no accurate outputs. The use of real dosimetry inside human heterogeneous phantom gives answers of these differences. TLD-100H has high sensitivity for radiation doses than other TLD types and can be reused but it cannot keep signals after annealing procedures to get one signal by the use of Harshaw® TLD reader.
Author Keywords: dosimetry, heterogeneity, MammoSite, radiation, treatment planning.

Abstract
Human body organs and tissue have different values of density. The nature of interaction between radiation and organs is not the same due to differences in density of medium, and energy and type of radiation. Low density medium has high range of energetic radiation inside the medium with low values of mass attenuation coefficient. Treatment plan considers the densities of human tissues and organs like water density, so readings of predicted doses inside body have no accurate outputs. The use of real dosimetry inside human heterogeneous phantom gives answers of these differences. TLD-100H has high sensitivity for radiation doses than other TLD types and can be reused but it cannot keep signals after annealing procedures to get one signal by the use of Harshaw® TLD reader.
Author Keywords: dosimetry, heterogeneity, MammoSite, radiation, treatment planning.
