Abstract

Effective atomic numbers Z eff, air-kerma and energy-absorption buildup factors, EABF for some human organs and tissues, vitamins and tissue substitutes have been computed in the present work. Geometric-Progression (G-P) fitting method was applied for computation of EABF. It is observed that the EABF and air-kerma are dependent upon Z eff and chemical compositions. The EABF, Z eff and air-kerma of calcium carbonate and lithium carbonate are found in good agreement with cortical bone and fat, respectively. The EABF in the present work could be useful in medical diagnostics, radiation therapy procedures and also personal monitoring.
