چکیده
Introduction: In this study, a specific combination (70% W 18.61% Ni and 11.39% C) of lead free and flexible putty metal is introduced and validated as internal shielding by Mont Carlo study
Materials and Methods: To evaluate putty metal as an internal shielding by Mont Carlo study Varian 2100 C/D was validated within measurement and then by given energy spectrum of Varian 2100 C/D shield thickness and backscatter factor were obtained by Mont Carlo study and compared to those of lead.
Results: The results showed that this putty metal shield required comparable thickness for providing protection compared to lead. In addition, it is nontoxic and flexible in that it can be easily cut. Internal shielding with high atomic number causes dose enhancement that isn’t taken into account in treatment planning system. This study showed that this composition as internal shield causes 5-7% reduction of electron backscatter factor relative Lead.
Conclusion: it can be concluded that lead can be replaced by putty metal with specific combination (70% W, 18.61% Ni and 11.39% C). It is Lead free, flexible and thickness required for protecting tissue is acceptable under clinical condition and it causes 5 -7% reduction of electron backscattering
