CELLULAR PHONES AND RADIATION RISKS
Some people worry that wireless and cellular phones cause cancer. Cellular phones give off radio-frequency energy (RF), a form of electromagnetic radiation. Scientists need to do more research on this before they can say for sure.
- Cellular telephones emit radiofrequency (RF) energy
- Exposure to high levels of RF energy can heat body tissue, but RF energy exposures from cellular telephones are too low to cause significant tissue heating
- Concerns have been raised that RF energy from cellular telephones may pose a cancer risk to users
- Researchers are studying tumors of the brain and central nervous system (CNS) because cellular telephones are held next to the head when used
- Studies have not shown any consistent link between cellular telephone use and cancer, but scientists feel that additional research is needed before firm conclusions can be drawn
