艹， 强电和弱电的区别又不是依靠电磁波大小决定的， 而是电压, 频率和功率。 而且辐射也分电离辐射和非电离辐射， 你以为电磁波都像gamma，x射线？
Smart meters emit RF waves, which are a type of electromagnetic radiation, so there is the potential for them to cause harm. The actual risk of harm, if it exists, is likely to be extremely low, for a number of reasons.
The RF waves that smart meters give off are a form of electromagnetic energy that falls between FM radio waves and microwaves. Like FM radio waves, microwaves, visible light, and heat, RF waves are a form of non-ionizing radiation. They don’t have enough energy to cause cancer by directly damaging the DNA inside cells. RF waves are different from stronger (ionizing) types of radiation such as x-rays, gamma rays, and ultraviolet (UV) light, which can break the chemical bonds in DNA. Long-term exposure to ionizing radiation is a known cause of cancer.
