A study by scientists in Finland has found that mobile phone radiation can cause changes in human ceils that might affect the brain, the leader of the research team said.
But Darius Leszczynski, who headed the g-year study and will present findings next week at a conference in Quebec(魁北克), said more research was needed to determine the seriousness of the changes and their impact on the brain or the body.
The study at Finland’s Radiation and Nuclear Safety Authority found that exposure to radiation from mobile phones can cause increased activity in hundreds of proteins in human 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 findings of which were published last month in the scientific journal
A. Fatigue.
B. Headache.
C. Alzheimer's disease.
D. Tuberculosis.
