An in-vivo study on the energy dependence of X-ray biological effectiveness
Background: The International Commission on Radiological Protection (ICRP) has attributed the same relative risk for X and gamma radiations of all energies. Several studies have proven that the biological effect of low energy photon is more than that of higher ones. The assessment of risks is important due to the wide use of low energy X-rays for mammography screening and other diagnostic appli...
متن کاملSex determination by the length ratio of metacarpals and phalanges: X-ray study on Iranian population
Background: In forensic anthropological identification, we usually use body remains. Accurate sex estimation from these remains is very important and needs the knowledge of specific population standards of that area. Sometimes, human remains are damaged by environmental circumstances. So, we must examine single bones for sex estimation. One of the relatively resistant bones to environmental con...
متن کاملDetermination of cristobalite phase content in ceramic cores using various X-ray quantitative phase analysis methods
The aim of this research is to investigate different X-ray based quantitative phase analysis methods for determination of cristobalite phase content in ceramic cores. For this purpose, four popular routes including peak absolute intensity method, relative intensity ratio method, direct or calibration method and internal standard (or Alexander-Klug) method have been chosen. Some control samples ...
متن کاملEFFECTIVE X-RAY BREMSSTRAHLUNG SOURCE (Is it possible to handle quality of the X-ray bremsstrahlung?)
The efficiency of new nontraditional scheme for generating bremsstrahlung is studied by means of computer simulation. In this scheme the electron beam multiply crosses a thin target due to the presence of special focusing magnetic field [1]. It is showed that one could expect more than two times increasing of the radiation yield power. 1 NEW SCHEME OF EFFECTIVE BREMSSTRAHLUNG SOURCE The X-ray r...
متن کاملDistance Determination Using X - Ray Scattering
We examine the feasibility of using dust-scattered X-rays for direct determination of distances to nearby galaxies with bright background AGNs, QSOs, or GRBs. We show how the Chandra X-Ray Observatory could be used to determine the distance to M31 to an unprecedented absolute accuracy of ∼ 1%.
