The chemical and physical characteristics of several flavonoid compounds such as geraniol, thymoquinone, betaine, apigenin, N-acetylcysteine, catechin, l -carnosine, epigallocatachin, saponarin were examined in this work. Numerous molecular properties all used study calculated using the Calculate Molecular Properties module Accelrys Discovery Studio v20.1.0.19295.0. These included polar surface...

Introduction Radon is a colorless and tasteless gas which exists in most soils. It is a substance that poses a potential risk for lung cancer in case a person is exposed to high levels over long periods of time. The Environmental Protection Agency (EPA) estimates that 90% of lung cancers per year are caused by radon. The aim of this paper is to estimate the absorbed doses of 222Rn by MCNPX simu...

We studied the effects of a dry rock sitting on a 3% water-containing martian-surface soil on neutron and gamma-ray fluxes. Rocks with radii of ~25 cm and bigger significantly affect these fluxes and the flux ratios of certain gamma rays. Introduction: The rock surface abundances on Mars are inferred from orbital data to vary from almost zero to ~30% [1]. These rock abundances are consistent wi...

Introduction: Passage of ionizing radiation through the organs of living creatures develops clusters of damaged nucleotides inside the DNA rounds. 192Ir Gamma source is one of the most widely used sources in brachytherapy of cervical and prostate cancer. Thus, in this research, we investigated the flux of photons and its resulting secondary electrons, the single-strand break (S...

Abstract Gamma-ray shielding properties of eight different metallic glasses based on Cu x Zr100- : = 35 (Cu35Zr65) ? 70 (Cu70Zr30) were determined using Monte Carlo simulations and Phy-X/PSD software. A typical gamma-ray transmission setup has been modeled in MCNPX code. The general trend the linear attenuation coefficients ( ? ) was reported as Cu35Zr65 < Cu40Zr60 Cu45Zr55 Cu50Zr50 Cu55Zr45...

Introduction One of the best methods in the diagnosis and control of breast cancer is mammography. The importance of mammography is directly related to its value in the detection of breast cancer in the early stages, which leads to a more effective treatment. The purpose of this article was to calculate the X-ray spectrum in a mammography system with Monte Carlo codes, including MCNPX and MCNP5...

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.

Neutron streaming through penetrations compromises the shielding performance of fusion devices. To characterize the problem, the effects of neutron streaming through the divertor Heaccess pipe on the peaking of radiation-induced damage across the ARIES-CS power plant components were compared to the nominal values for the different components. The results show that due to streaming the damage ex...
