title: Study of Zeff for DNA, RNA and retina by numerical methods.
abstract: The effective atomic number of a biomolecule for photon interaction present in DNA, RNA and retina has been estimated in the energy range 0.001-20 MeV using two different numerical methods. The significant variation of Zeff with photon energy is reported. This shows that Zeff is not constant with energy for photon interaction in DNA, RNA and retinal.
