Radio galaxies are complex and diverse X-ray emitters.
Current answers to key questions are presented. The imaging and spectroscopic results obtained by the PSPC are used to obtain fluxes for the non-thermal core sources and structures for the atmospheres of the host galaxies or their groups. The implications for the environments of the radio jets and for the radio cores are discussed. To appear in Energy Transport in Radio Galaxies and Quasars , P. E. Hardee, A. H. Bridle, and A.
