Mobile phone use and Wi-Fi can have health effects, some studies have found. Such studies have been conducted on many types of non-ionizing radiation, for decades.
Non-ionizing radiation includes exposures such as electromagnetic fields (EMF) produced by power lines, radio frequency energy used in microwave ovens or emitted by cell phones, and solar ultraviolet radiation. Whether such exposure is dangerous, or not, has been argued for decades.
Prudent usage is the advice sometimes given for using any products that product non-ionizing radiation.
Some have argued such potential effects are reasons for not deploying new mobile networks. Others have argued users simply have to be conscious of potential risks and adjust usage accordingly.
As with nearly all technologies, risks and rewards have to be balanced. There are some risks associated with automobiles and airplane travel, for example, and most us can balance the risk of using or not using those technologies.
Flying in an airplane does expose passengers and crew to more solar radiation than is experienced at ground level. So people have to balance such risks with the benefits of flying.
That is not a bad way to balance other risks as well. Be prudent.
