Kybernetische Aspekte der Strahlenschädigung

Starting with experimentally established radiobiological facts concerning cellular effects of ionizing radiation, the differences between single cells and tissues are discussed. A new classification for “size”-controlled tissues is proposed, and the relevant mathematical formulations are outlined. It is suggested that the different sensitivities of tissues against ionizing radiation may be explained on the basis of differently operating control mechanisms. As examples, root meristems, intestinal epithelium and blood forming organs are described in more detail.
