Characterization of the Urethane Based Tissue Equivalent Substitute for Phantom Construction: Model Molding, XCOM and MCNPX Studies

open access: yesInternational Journal on Advanced Science, Engineering and Information Technology, 2022
The Soft and Lung tissue equivalent substitute (STES and LTES) were developed from urethane PMC121/30 Dry (A and B) of Smooth-On, USA. The part A and B were mixed in the ratio 1:1 and further mixed with calcium carbonate (CaCO3) at a ratio 2:1 by mass. Air moisture was extracted from the mixture for 10minutes. This is the STES and the density after air

Comparison of mass attenuation coefficients of concretes using FLUKA, XCOM and experiment results

open access: yesRadioprotection, 2018
The mass attenuation coefficients of seven different types of normal and heavy concretes like ordinary, hematite-serpentine, ilmenite-limonite, basalt-magnetite, ilmenite, steel-scrap and steel-magnetite concretes has been simulated using FLUKA Monte Carlo code at high energies 1.5, 2, 3, 4, 5 and 6 MeV.

Low Energy Electron and Nuclear Recoil Thresholds in the DRIFT-II Negative Ion TPC for Dark Matter Searches [PDF]

open access: yes, 2009
Understanding the ability to measure and discriminate particle events at the lowest possible energy is an essential requirement in developing new experiments to search for weakly interacting massive particle (WIMP) dark matter. In this paper we detail an

New beam hardened data correction and its application to artifact reduction in CT images

open access: yesMedical Physics, Volume 53, Issue 2, February 2026.
Abstract Background Beam hardening is an unavoidable phenomenon in polychromatic CT systems, where lower‐energy photons are preferentially absorbed as x‐rays pass through materials such as tissue, bone, and metal. This energy‐dependent attenuation, which conflicts with the monochromatic assumption in filtered back‐projection (FBP), produces artifacts ...

Radiation shielding ability and optical features of La2O3+TiO2+Nb2O5+WO3+X2O3 (X=B, Ga, and In) glass system containing high-entropy oxides

open access: yesHeliyon, 2023
Three high entropy materials (La2O3+TiO2+Nb2O5+WO3+X2O3 coded as LTNWM1, LTNWM2, and LTNWM3 for X = B, Ga, and In) produced by aerodynamic containerless processing were evaluated for optical attributes, and their gamma-radiation absorption abilities were

Generation of 3D reference dosimetric datasets towards adoption of model‐based dose calculations for permanent implant prostate brachytherapy

open access: yesMedical Physics, Volume 53, Issue 2, February 2026.
Abstract Purpose This work aims to create and validate a comprehensive set of test cases and 3D reference dosimetric datasets for model‐based dose calculation algorithms (MBDCAs) in permanent implant prostate brachytherapy. These test cases address the limits of the standard TG‐43 formalism towards improving dose evaluations in prostate cancer ...

Lifted Variable Elimination for Probabilistic Logic Programming

open access: yes, 2014
Lifted inference has been proposed for various probabilistic logical frameworks in order to compute the probability of queries in a time that depends on the size of the domains of the random variables rather than the number of instances.
