10、ce in Quebec, said more research was needed to determine the seriousness of the changes and their impact on the brain or the body.The study at Finlands Radiation and Nuclear Safety Authority found that exposure to radiation from mobile phones can cause increased activity in hundreds of proteins in h
11、uman cells grown in a laboratory, he said.“We know that there is some biological response. We can detect it, with our very sensitive approaches, but we do not know whether it can have any physiological effects on the human brain or human body,“ Leszczynski said.Nonetheless the study, the initial fin
