Have you ever know, What is radiation? How many types of radiation?
Radiation is the emission of energy in the form of waves, such as radio waves, microwaves, infrared, ultraviolet, x-rays, gamma rays.
Yes, Radiation cause cancer, but all radiation does not cause cancer.
Because from ultraviolet Ray's to gamma Ray's has Ionizing radiation. Ionizing radiation emits excess amount of energy, that is harmful for human health. If we exposed to ultraviolet rays, x-rays, gamma Ray's then DNA structure will be changes and it's cause cancer and also damage to our eyes.
But radio and cell phone waves not having much power to harmful to human health. Radio frequency waves have low energy and this is coming in Non-Ionizing radiation category.
Cell phone towers used 700 MHz - 2.5 GHz spectrum bands that's under low energy level. In short, cell phones radiation not harmful for our health.
Our mobile phone has a radio transmitter and receiver. It is designed not to exceed permissible limits for exposure to radio waves prescribed by Indian Government Guidelines. The SAR (Specific Absorption Rate) limit for mobile phone devices is 1.6 W/kg in india, Mobile phones under this SAR value limit consider as safe.
