Abstract: The effective atomic number (Zeff)and electron density (Nel) of coumarinderivatives 1IPBCand 4IP6MC have been calculated for all photon interactions [coherent, incoherent, photoelectric, pair production in the field of electric and nuclear, total photon interaction (with coherent and incoherent)] in the energy range 1 keV to 100 GeV using the WinXCom program. The significant variation of photon mass attenuation coefficient, Zeffand Nelis due to the variations in the dominance of different interaction processes in different energy regions. The maximum values of Zeff and Nel are found in the low-energy range (E> 0.5 MeV), where photoelectric absorption is the main interaction process for total photon interaction(with coherent). The minimum values of Zeff and Nel are found at intermediate energies, typically 2 MeV<E<400 MeV, where Compton scattering is dominant. Above 400 MeV, Zeffand Nel assumes an almost constant value determined by pair production. The Kerma (Ka) values also have been calculated for energy range 1 keV- 20 MeV. It is to be noted thatkavalues show sharp peak due to photoelectric absorption of the high-Z constituent of the compound.
