In this study the value of linear  and mass  attenuation coefficients of Aluminum element (Al) were determinated by using x-ray Cu-tube of energies CuKα (8.048) KeV, CuKβ (8.906) KeV, and Mo-tube of energies MoKα (17.480) KeV and MoKβ (19.609) KeV.the voltage between the two electrodes are up to 35 KV.The measured  values are compared with other experimental data showing a general agreement within a precision of 0.2% - 0.8%. The mass attenuation cross-sections were thus derived and compared with other experimental data available on database of x-ray attenuation cross-sections. The agreement is always within ±7%.   http://dx.doi.org/10.25130/tjps.24.2019.013

The aim of the research is to estimate the X-ray shielding properties of different glass systems using Monte Carlo Simulation. X-ray glass is also known as radiation shielding glass. Glass provides protection against the absorption of energy radiation. The shielding layer is formed by a high concentration of lead and barium. The mass attenuation coefficient, the effective atomic number and the effective electron density are used to determine the position of gamma-ray photons in matter. Shield characterization in terms of mass attenuation coefficient (μm), transmission fraction (T), effective atomic numbers (Zeff), half-value layer (HVL) and exposure build-up. factor (EBF) of a glass system is estimated by the Monte Carlo Simulation. The random sampling and statistical analysis are computed using the monte carlo simulation. Various external factors are considered as the input parameters. The different composition of the glass will be examined using the Monte Carlo simulation and the shielding capability would be determined for the various samples.

AbstractAn X-ray diffraction method has been successfully applied to the quantitative determination of mineral mixtures. The absorptive properties of the samples and the number of components determine the analytical procedure to be used. The methods described (external standard plus empirical determination of the mass attenuation coefficient) provides an accurate and rapid alternative to the direct measurement of the mass attenuation, Compton diffusion or internal standard methods. The relative accuracy obtained is of the order of 10% at the 0.1% level, independent of the sample composition.
