While talking on these phones we don’t know, our communication is transmitted by radio waves through a network of fixed antennas called base stations. The radio frequency waves used for transmit are electromagnetic fields. The fact is these electromagnetic fields produced by mobile/cellular phones are classified by IARC (International Agency for Research on Cancer) as possibly carcinogenic to human.
Dr. George Carlo, public health scientist and ones of the world’s top expert s on the health affect radiation on human body has explained health effects of radiation on body:
The near-field radiation plume:
1- The handset only transmits power when it is turned on. So, the radio frequency drops down with increasing distance from the handset.
2- Keep your hand set away (30-40 cm) from body while using internet and text messaging.
3- Use hand free devices, which keeps mobile/cell phones away from head.
4- Try to use phones in area of good reception because it allows phone to transmit at reduced power.
5- Don’t use cell phone in hospitals and airplanes (prohibited areas) , as the radio frequency signals may intrude certain electro-medical devices and navigation system.
WHO (world health organization) is planning to conduct a formal risk assessment of all studies health outcomes from radio frequency fields exposure this year (2012).
