Chromosomal aberration of human lymphocytes at G,0, phases of cell cycle induced by tritium ,β,-rays and ,60,Co γ-rays were investigated. Dose-response relationship has been observed (dose range from 0 to 0.5 Gy). The results showed that chromosomal type aberration is main aberration for both radiations and the data of dicentrics gave the best fit to the linear model respectively Y=- 0.0824+ 0.0555 D and Y=- 0.0719+0.0263 D. Taking ,60,Co γ-rays as a reference source, the RBE value of dicentrics for tritium ,β,-rays irradiation was estimated to be 2.
