Radiofrequency (RF) radiation is at the low-energy end of the electromagnetic spectrum and is a type of non-ionizing radiation. Non-ionizing radiation has enough energy to move atoms in a molecule around or cause them to vibrate, but not enough to ionize (remove charged particles such as electrons).icrowave ovens work by using very high levels of a certain frequency of RF radiation (in the microwave spectrum) to heat foods. When microwaves are absorbed by food containing water, it causes the water molecules to vibrate. This produces heat.
There still aren't any good explanations for how mobile phones could cause cancer. The radiofrequency electromagnetic radiation they transmit and receive is very weak. This radiation does not have enough energy to damage DNA, and cannot directly cause cancer.In 2012 an independent report concluded that there is no convincing evidence that being exposed to radiofrequency fields, including those from mobile phones, within the guidelines could affect somebody's health.here has been some media speculation that Wireless internet (Wi-Fi) and smart meters, which can be used to record energy use in your home and transmit it back to your energy provider, could cause cancer. Smart meters and Wi-Fi both use radio waves to send information.
