3、tists at the National Institute of Health said at a conference last month, adding that the study will not likely settle concerns of a link between cell phones and brain cancer.

4、d to a cell phone in the area closest to the antenna, said Dr. Nora Volkow of the NIH, whose study was published in the Journal of the American Medical Association.

5、s surprised that the weak electromagnetic radiation (电磁辐射) from cell phones could affect brain activity, but she said the findings do not shed any light on whether cell phones cause Cancer.

8、nt increase in brain metabolism in the region closest to the cell phone antenna when the phone was on. (77) Experts said the results were interesting, but urged that they be understood with great care.“Although the biological significance, if any, of increased glucose metabolism from too much cell p

9、hone exposure is unknown, the results require further investigation,” Henry Lai of the University of Washington in the U.S. and Dr. Lennart Hardell of University Hospital in Sweden, wrote in an article in JAMA. “Much has to be done to further investigate and understand these effects,” they wrote. 1.
