Abstract
The relative biological effectiveness has been measured for the biological characterization of p^(+)(50.5 MeV) Be neutron of KCCH-Cyclotron prior to clinical application. Measured RBE of mouse jejunal crypt cell in single whole body irradiation was 2.8. This RBE value is changed differently in different biologic systems such as mouse jejunal crypt cells, intestine and bone marrow in different irradiation method, so that in fractionated irradiation, RBE is variable to the different fraction size and total dose, and also variable to the number of fractions.
