The guidelines recommend keeping phones away from the body when they’re not in use—in a backpack, for example, rather than a pocket—and sleeping with phones away from the bed. People may also choose to use speakerphone or a headset to make calls, rather than holding the phone to their heads. (They should remove their headsets when they’re not in use, though, as these devices also emit small amounts of RF frequency.)
In subsequent analyses of Interphone data, investigators addressed issues of risk according to specific location of the tumor and estimated exposures. One analysis of data from seven of the countries in the Interphone study found no relationship between brain tumor location and regions of the brain that were exposed to the highest level of radiofrequency radiation from cell phones (9). However, another study, using data from five of the countries, reported suggestions of an increased risk of glioma and, to a lesser extent, of meningioma developing in areas of the brain experiencing the highest exposure (10).
The 13-country INTERPHONE study, the largest case-control study done to date, looked at cell phone use among more than 5,000 people who developed brain tumors (gliomas or meningiomas) and a similar group of people without tumors. Overall, the study found no link between brain tumor risk and the frequency of calls, longer call time, or cell phone use for 10 or more years. There was a suggestion of a possible increased risk of glioma, and a smaller suggestion of an increased risk of meningioma, in the 10% of people who used their cell phones the most. But this finding was hard to interpret because some people in the study reported implausibly high cell phone use, as well as other issues. The researchers noted that the shortcomings of the study prevented them from drawing any firm conclusions, and that more research was needed.
For those of you who experience (or want to prevent) ES symptoms in your hands when using a computer keyboard, laptop, cell phone or other electronic devices, these gloves form a conductive enclosure and effectively shield radiowaves and electric fields. Soft, light weight, with ribbed cuff, and offering good tactile sensitivity. Polyester fiber is twisted with pure Silver fibers, then knit into a stretchy glove shape in basic gray color. Each glove has a 1.7 mm snap for a ground cord. Fully hand washable and tested for 50 cycles with no appreciable loss of conductivity. All fibers are conductive, achieving resistivity of less than 10 Ohm/sq. These gloves are also used in industry for static control when working with delicate static sensitive components and can even be used for TENS applications. Grounding is not necessary for Faraday Cage shielding effect, but is necessary for static control. Also useful on touch screens like an iGlove. We do not have the ground cord which fits this snap on these gloves. Shielded Gloves:
The energy of electromagnetic radiation is determined by its frequency; ionizing radiation is high frequency, and therefore high energy, whereas non-ionizing radiation is low frequency, and therefore low energy. The NCI fact sheet Electromagnetic Fields and Cancer lists sources of radiofrequency radiation. More information about ionizing radiation can be found on the Radiation page.
