When protein was irradiated by gamma rays from a cobalt 60 source, an activated state was caused. An empirical equation for the viscosity change was obtained, and the phenomena were explained on the basis of the molecular mechanism. The general equation for the viscosity change is given by η red = ( b + a log R )(1 − e − kt ), where η red is the reduced viscosity of the solution, R is the gamma radiation dose, and t is time.
