- "Cell phones emit radio frequency energy, a form of non-ionizing electromagnetic radiation, which can be absorbed by tissues closest to where the phone is held." (National Cancer Institute)
What determines the amount of energy people exposed to the radiation?
- The amount of radio frequency energy a cell phone user is exposed to depends on the technology of the phone, the distance between the phone’s antenna and the user, the extent and type of use, and the user’s distance from cell phone towers. (National Cancer Institute)
- "The RF waves from cell phones come from the antenna, which is part of the body of a hand-held phone. The waves are strongest at the antenna and lose energy quickly as they travel away from the phone. The phone is typically held against the side of the head when in use. The closer the antenna is to the head, the greater a person's expected exposure to RF energy. The body tissues closest to the phone absorb more energy than tissues farther away." (American Cancer Society)
Factors affect the amount of RF energy to which a person is exposed: (American Cancer Society)- "The amount of time on phone"
- "Whether or not is using the speaker mode or a hands-free device. Using one of these allows the phone to be held away from the head."
- "The distance and path to the nearest cell phone tower. Cell phones adjust their power to use the minimum amount for a good signal, so being farther away from the tower requires more energy to get a good signal, as does being inside a building."
- "The amount of cell phone traffic in the area at the time. Higher traffic may require more energy to get a good signal."
- "The model of phone being used. Different phones give off different amounts of energy."
What kind of population does the cell phone radiation hurt most?
- Phones Carried on Belt or in Pants Pocket May Harm Reproductive Health, the radiation can damage sperms. (Environmental Science Group)
- The bone marrow of a child’s head absorbs 10 times more radiation than an adult, while those of infants and toddlers will absorb even more. (Australian Government)
How to prevent cell phone radiation harm? (Megan)
- Use hands free devices or switch the cell phone to speaker mode when chat with others
- Reduce the amount of time on phone
- Keep the phone away from your body
- Use the cell phone when there is maximum amount of bars of signal
- Use a wireless land-line when you are at home
