How efficient are metal‐polymer and dual‐metals‐polymer non‐lead radiation shields?

open access: yesJournal of Medical Radiation Sciences, Volume 71, Issue 1, Page 57-62, March 2024.
Replacing lead radiation aprons with lead‐free aprons is a challenge in radiation protection. In this study, the attenuation capability of non‐lead radiation shields made of one or two metallic compounds together with polymer was evaluated. The results showed that some dual‐metals‐polymer compounds such as Bi2O3‐BaSO4‐PVC are capable of reducing the ...

Total body irradiation delivered using a dedicated Co‐60 TBI unit: Evaluation of dosimetric uniformity and dose verification

open access: yesJournal of Applied Clinical Medical Physics, Volume 25, Issue 2, February 2024.
Abstract This work presents the dosimetric characteristics of Total Body Irradiation (TBI) delivered using a dedicated Co‐60 TBI unit. We demonstrate the ability to deliver a uniform dose to the entire patient without the need for a beam spoiler or patient‐specific compensation.

Monte-Carlo Modelling For Evaluation Of Two Different Calculation Algorithms

open access: yesBrazilian Journal of Radiation Sciences, 2019
Modeling of linac head (VARIAN Trilogy) for 6 MeV photon beam was performed using BEAMnrc code package (BEAMnrc 2017). The DOSXYZnrc code was used to determine the percentage depth dose (PDD profiles) and beam profiles for different symmetric square ...
