As a basis for the explanation of the effects of ionizing radiation on bacteria, water radiolysis is discussed, since the bacterium cell is 85 to 90% water. First of all, H-atoms and OH-radicals are formed. The inactivation consists of the direct tanget theory and the indirect action of the modified water and cell molecules. As an e-function in semilogarithmic representation, the curve is frequently a straight line, but it may also take sigmoidal shapes. The dependence on outside influences such as initial concentration of bacteria, time, dosage, age medium, or nutritive substrate is discussed. Among the vegetative microorganisms, the gram-negative ones are the most sensitive, then follow the gram-positive, whereas the spores are considerably more resistant to radiation. In conclusion, a brief outlook on practical applications in radiation sterilization is given. (auth)
