"The voluntary exposure of the brain to microwaves from hand-held mobile phones... [is] the largest human biological experiment ever." - Professor Leif Salford, Head of Research at Lund University, Sweden
Exposure to radiation from cell phones is a growing concern, not only in the United States, but around the world. As more and more studies point towards a link between cell phone radiation and headaches, certain types of cancer and even lowered sperm count, consumers are searching for ways to protect themselves from this potential threat.
Is Cell Phone Radiation Really Harmful?
The problem is that no definitive studies are available, one way or the other. With some scientists still arguing that cell phone radiation isn't dangerous at all, how is a consumer to know who to trust? Recently, several companies have created cell phone radiation blockers to ease the concerns of some cell phone users. Those who choose to do so can simply use this accessory to block up to 99% of cell phone radiation.
All cell phones and cell phone towers emit Radio Frequency (RF) energy, a type of electromagnetic energy. This RF energy differs from the type of electromagnetic energy found in gamma rays and x-rays and has been thought of until recently to be completely harmless. X-rays are a type of ionizing radiation, meaning that they damage human cells by stripping electrons away from their normal locations.
Since RF energy is non-ionizing, scientists believed that it would not have this same effect on human cells. However, tests on animals show that the heat created by cell phone radiation can indeed damage cells by overheating them. The extent of the damage is impossible to know or understand until further testing is done, but this type of testing on humans is a moral and ethical no-no.
How Cell Phone Radiation Shields Work
As their name suggests, these cell phone accessories simply block cell phone radiation, preventing it from entering the ear or head. They are usually made of ceramic or other conductive materials and are readily available in stores or online for most cell phone models.
Some critics still believe that these devices are not enough. After all, cell phone radiation is all around us, especially in high population density areas and locations near cell phone towers. What else can be done to protect yourself from the harmful effects of cell phone radiation?
Reduce Your Exposure To Cell Phone Radiation
Since studies have shown that the overheating effect of cell phone radiation on the brain can occur in just minutes, limit your calls to those that are absolutely necessary. Use a landline for longer telephone calls.
Do your research before buying a wireless device. Most cell phones sold in the United States list their Specific Absorption Rate (SAR) in their manual. This number refers to the actual amount of RF energy absorbed by the body, so a lower number indicates a lower radiation exposure risk.
Invest in an airtube headset. While many people believe that using a headset offers some kind of protection, regular headsets actually intensify the radiation as it enters the ear canal. Avoid using your cell phone in metallic enclosures such as elevators, where radiation has nowhere to go but into your body.
Limit your cell phone use and choose cell phone radiation blockers as an extra measure of precaution. Until more is known about RF energy and the effects it has on the human body, it is up to you to protect yourself as best you can!
