Measurement And Calculation Of The Linear And Mass Attenuation Coefficient Of X-Ray For Some Materials

Abstract

The attenuation measurements of X-Rays for the voltage range of (15-35) KV for the Wood were done by using X-Ray unit with two X-ray tubes (Cu-tube and Mo-tube) and G-M counter.The linear attenuation coefficients (µL) were concluded for the voltage range mentioned above through the linear equations of the Yeild of graphic representation operation between the logarithmic absorption and the sample thickness X(cm) , The mass attenuation coefficient µm were also concluded through the graphic relation between the logarithmic absorption and the equivalence thickness of the samples X m(gm/cm2) such that the slope of the graphic relation represents the attenuation coefficient either linear or mass .The linear relation between the logarithmic absorption of X-rays with the thickness and equivalent thickness sample were concluded. Inverse relation between the linear and mass attenuation coefficients with X-ray voltage were also concluded of samples.
