Introduction to radiation biology pdf

This book is about radiation, radioactive decays and some elements of nuclear and particle physics. Einstein's theory of special relativity is needed for a correct description of some of these phenomena. The word "special" is used to distinguish this part from the theory of general relativity that deals with non-inertial reference frames and with gravity. Some textbooks follow a rather radiation exposure to a cell, there is a latent period before any observable response. The latent period could be decades for low radiation doses, but only minutes or hours for high radiation exposure. These basic generalizations form the foundation on which radiation biology is based (4). RADIATION INTERACTIONS WITH HUMAN CELLS radiation response of cells in the low dose region (0-3 Gy) f = e--((αD +D +βD2) Gives a continuously bending survival curve with no straight portion at high radiation doses Shape or bendiness of the curve is determined by the α/βratio; represents the dose (Gy) at which linear contribution to cell kill equals quadratic contribution.

Although the field of radiation biology is rapidly evolving as a result of advances in molecular biology and genetics and the availability of new technologies, a thorough understanding of the established factors that Four things can happen when radiation enters a cell: 1. The radiation may pass through without any damage occurring; 2. The radiation may damage the cell, but the cell repairs the damage; 3. The radiation may damage the cell…the damage is not repaired…and the cell replicates itself in the damaged form; 4. The cell dies.
