This chapter focuses on the basic features of photo- and radiation-chemical reactions as far as they are relevant for the understanding of biological processes. These include the basic mechanisms of photosensitization and of action spectroscopy which allows to identify the primary absorber in a biological effect by studying its wavelength dependence. More specifically, atmospheric photochemical reactions and the light-dependent formation of vitamin D are discussed. The decomposition of water is described and, particular attention is paid to the influence of oxygen and different ionization densities, providing the background for the understanding of cellular phenomena. The chapter concludes with a discussion of direct and indirect radiation effects.
