Abstract
Effective atomic numbers are derived for the low-Z compounds polyethyl ene, polycarbonate, Teflon, Mylar, polystyrene, and polyvinyl chloride for total photon interaction in the 10- to 20 000-keV energy region. The number generally decreases and then increases with increasing ener gy. This variation is based on the effective atomic numbers for photoe lectric, incoherent scattering, and pair production partial photon int eraction processes.
