Radiofrequency (RF) Radiation
Radiofrequency (RF) radiation is used in many broadcast and communication applications, including cellular phones and wearable technologies. RF is a form of non-ionizing radiation that has the lowest energy in the electromagnetic spectrum. Non-ionizing radiation does not have enough energy to remove electrons from atoms and molecules but has enough energy to heat substances such as in a microwave.
