      The calculation of the value of stopping power and the range for the proton is done by two ways : first, using Bethe-Bloch formula and second, using Bragg-Kleeman rule. The differences between the experimental and theoretical values of stopping power and range required studying  the corrections for Bethe-Bloch formula which are represented by the maximum energy and density correction and then comparing the results with experimental values.

 The aim of this study is to detect the radioactivity of radionuclides and measure the specific activities and the uranium concentration in (30) samples of crude oil and oil waste were brought from three oil locations Dora refinery, Bijie refinery, and north field of al-Rumaila.The measurements in this study were done by using two techniques:   

      Aluminum matrix composites reinforced with boron carbide are currently employed in the nuclear industry. It's used as a control rod in nuclear reactors; Since B C has very high absorption cross section for
