Özet

Dosimetric materials have been investigated in terms of calculated mass energy absorption coefficient, equivalent atomic number and KERMA (kinetic energy released per unit mass) in the energy range 0.015-15 MeV. Using analytical methodology it has verified that nylon is the best substitute dosimetric material for skin, muscle, bone and soft-tissues. Relative energy absorption buildup factors calculated by G-P fitting method confirm the findings. Nylon has been found to be good tissue substitute material for making tissue-phantoms of the biological tissues investigated. (C) 2011 Elsevier Ltd. All rights reserved.
