Fig. 3From: In vitro effects of 0 to 120 Grays of irradiation on bone viability and release of growth factorsRelative cell viability of bone cells following irradiation at varying concentrations of Grays relative to control samples. Over 85 % of all cells were non-vital in samples receiving as little as 7.5 Gy and all cells were non-vital following 60 Gy.
