The study specifically used 2G and 3G frequencies — not the frequencies used on more advanced 4G or 5G networks. Researchers exposed the rodents’ entire bodies to the radiowaves for more than nine hours per day, for up to two years. (“A rat that is 2 years old is roughly equivalent to a 70-year-old person,” STAT News reports.) These exposure levels were much higher than what people would experience, John Bucher, senior scientist with the NTP, says in a statement. “So, these findings should not be directly extrapolated to human cell phone usage,” he says.
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:
Another way to think about the situation is to consider the steady state power emission of .02 Watts and ask how long it would take to heat up your body by one degree Celsius if your entire volume was exposed. Take your body mass to be 100 kg and approximate it as being composed entirely of entirely of water. If all of the radiation was absorbed and went into heating you up (which it isn’t), it would take 20900000 seconds (specific heat*mass*1 degree/power) or 241 days to heat you up by one degree. Fortunately, you have metabolic processes in your body, or possibly air conditioning, to mitigate this heating.
Over time, the number of cell phone calls per day, the length of each call, and the amount of time people use cell phones have increased. Because of changes in cell phone technology and increases in the number of base stations for transmitting wireless signals, the exposure from cell phone use—power output—has changed, mostly lowered, in many regions of the United States (1).
