Calculation of Atomic Cross section &Electron Density for (Tissue and Bone ) using Monte Carlo program


journal of kerbala university, Volume 11, Issue 4, Pages 38-44

In the present work , calculated mass attenuation coefficients ,atomic cross section and electron density for these tissue and bone were theoretically calculated using monte carlo program within a range of energies of x-rays (16.5-17.5-21.5-24.5)keV .The attenuation coefficient of substances ,at any energy of x-ray photon ,is known to depends on the electron density and effective atomic number of the material .which makes it very sensitive to the index "x" .Several different values laying between) 0.5 - 2.5( step 0.5 have been suggested for the exponent "x".The results were compared with XCOM program .These theoretical values are found to be in agreement with the calculated from XCOM value .
