چکیده

Monte Carlo track structure simulation is a powerful method for estimating damage induced by water radiolysis products cell killing. To investigate the influence of multiple ionization formation under 1H+, 4He2+, and 12C6+ ion beams, based on Geant4-DNA was carried out. The G-value H2O2 increased monotonically with increasing linear energy transfer up to 200 eV/nm. Above eV/nm, began dropping, but only when considered. This trend in good agreement experimental results. Furthermore, we successfully reproduce results G-values HO2• + O2•−. role production H2O2, HO2•, O2•−, O2 also discussed.

Microdosimetry study of a multicellular model with mono-energetic electrons using Geant4-DNA simulation toolkit

Introduction: The goal of any type of radiation therapy in the treatment of tumors, in addition to destroying cancer cells, is to minimizing radiation to nearby healthy cells and thus reducing side damages. For this purpose, targeted radiation therapy (TRT) is more effective in treating of single cells or small cluster of cells. The main factor in the success of this method is...

a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...

reinsurance is widely recognized as an important instrument in the capital management of an insurance company as well as its risk management tool. this thesis is intended to determine premium rates for different types of reinsurance policies. also, given the fact that the reinsurance coverage of every company depends upon its reserves, so different types of reserves and the method of their calc...

beams: a study with the GEANT4 toolkit

We study the spatial distributions of β-activity produced by therapeutic beams of He and C ions in various tissue-like materials. The calculations were performed within a Monte Carlo model for Heavy-Ion Therapy (MCHIT) based on the GEANT4 toolkit. The contributions from positronemitting nuclei with T1/2 > 10 s, namely 10,11C, N, 14,15O, 17,18F and P, were calculated and compared with experiment...
