We report on the first detailed measurements of electron backscattering from low Z targets at energies up to 124 keV. Both energy and angular distributions of the backscattered electrons are measured and compared with electron transport simulations based on the GEANT4 and Penelope Monte Carlo simulation codes. Comparisons are also made with previous, less extensive, measurements and with measur...
The light output response and the neutron and gamma-ray detection efficiency are determined for liquid scintillator EJ-309. The light output function is compared to those of previous studies. Experimental efficiency results are compared to predictions from GEANT4, MCNPX and PENELOPE Monte Carlo simulations. The differences associated with the use of different light output functions are discussed.
Accounting for brachytherapy applicator attenuation is part of the recommendations from the recent report of AAPM Task Group 186. To do so, model based dose calculation algorithms require accurate modelling of the applicator geometry. This can be non-trivial in the case of irregularly shaped applicators such as the Fletcher Williamson gynaecological applicator or balloon applicators with possib...
Geant4 is a versatile Monte Carlo radiation transport simulation toolkit with steep learning curve. This work introduces user-code called M-TAG (Modular Radiation Teaching-Aid for Geant4), built on top of Geant4. designed to help gradually introduce the new users.The goal record quantities from simulated as it transported through geometries. simplifies inclusion geometric elements and detector ...
