Cell phones produce "non-ionizing" radiation, which, unlike X - or gamma rays, doesn't damage DNA by stripping away electrons from molecules in cell tissue.
手机产生“非电离”辐射，它不像X或伽马射线那样从细胞组织中的分子里分理出电子，从而破坏dna。

Stronger than FM radio signals, these RF waves are still abillionth the intensity of known carcinogenic radiation like X-rays. (See pictures from an X-ray studio.)
这些射频电波比调频收音机信号要强，其强度大约相当于X射线这类致癌放射线的十亿分之一。
