The biological effects of radiation depend on the source of radiation used. The quality of radiation delivered to the individual, to tissues, and to cells is measured in terms of absorbed dose (Gy), which reflects the quantity of ionization. If cells are irradiated with two radiations by the same absorbed dose, the same number of ionizations is introduced per unit volume. Actually, a value that considers the difference in biological effect is needed, because irradiation with the same absorbed dose induces different biological effects, depending on the type of radiation and/or radiation quality represented by the linear energy transfer (LET). Relative biological effectiveness (RBE) is used to show the difference in the biological effect, and in clinical and basic biological research, iso-effective dose which is often physical dose multiplied by RBE is used. In proton beam therapy, RBE = 1.1 is used as an international standard value. However, because RBE varies widely with dose, radiation quality, beam depth and biological endpoint. It is important to understand the effects of the factors for RBE to establish more higherdefinition and tailor-made proton therapy. This chapter details the basic concept of RBE and the factors that influence RBE value.
