Photo- and Radiation Chemistry of DNA,uch an exclusive statement is not possible although strand-breaks undoubtedly play a very important role. The influence of exposure conditions and modification by additives (photosensitizers, oxygen) are described as well as the dependence on ionization density.

Radiation Effects on Subcellular Systems,be given which describes quantitatively the effects on “small” systems. Investigations using viruses (especially bacteriophages), plasmids or isolated DNA are outlined. A special section deals with repair phenomena at the subcellular level. The chapter includes also a description of “gene mapping”,

Radiation and the Cell Cycle, is found both with UV and with sparsely ionizing radiations; in many cases, the two types show a mirror-image-like relationship. Radiation also slows down the progression of cells through the cycle; this effect is reversible with low doses. The inhibition of DNA synthesis is particularly relevant i

The time pattern of exposure plays an important role, both fundamentally and practically. With respect to the recent interest in hyperthermia in radiation therapy, the combination of heat and radiation at the cellular level is
