Proportional Counter in X-ray Fluorescence

Abstract

The purpose of this work is to investigate and quantify x-ray fluorescence, its production and its spectroscopy. Characteristic x-ray with different energies was obtained from six various elements using Am-241 source with 59.5 keV. It was found that x-ray energy and intensity increase with increasing atomic number of material. X-ray spectroscopy was studied for such elements in respect to their atomic number and intensity of Kα using proportional counter. Furthermore, x-ray fluorescence was produced from different thicknesses of copper foil using different energies. It was found that there is no substantial difference in x-ray fluorescence yield with higher thickness of the target.

The Use of the Stopping and Range of Ions in Matter Code for Calculation of Damage in Three Different Types of Steel

“…The capability of accelerated protons to emulate neutron damage in a short term way would be very useful as a means of testing material viability quickly during the design of a plant and would also offer the ability to test numerous variables (dose, dose rate, hardness, irradiation temperature, etc.) [4][5][6][7][8][9][10].…”

Experimental Study of the Pressure Effects on Stopping Power for Alpha Particles in Air

“…The directly ionizing radiations such as the α-particle, β-particles and many other charged particles ionize atoms of their target material due to Columbic collisions with the electrons of the material, and the amount of kinetic energies of these particles determines the amount of this Columbic force [3,4]. On the other hand, indirectly ionizing radiations are neutral particles such as high photons and neutrons which do not directly ionize atoms but undergo collisions to eject an energetic electron called the secondary electron [5][6][7][8][9][10]. Therefore undergoes direct ionization ejecting many other electrons leaving the atom ionized.…”

Investigation of Gamma Ray Buildup Factor for some Shielding Absorber

“…Second, indirectly ionizing radiations are neutral particles such as high energy photons and neutrons which do not directly ionize atoms but undergo interactions to eject an energetic electron called the secondary electron. Despite the fact that a large number of possible interaction mechanisms of gamma rays with matter are known, three processes are most important in the attenuation of gamma rays by matter [6][7][8][9]. These processes of interaction are photoelectric effect, Compton scattering and pair production.…”
