The Story Behind Cell Phone Radiation Research
XopherMV writes "A study by Lai and Singh, published in a 1995 issue of Bioelectromagnetics, found an increase in damaged DNA in the brain cells of rats after a single two-hour exposure to microwave radiation at levels considered "safe" by government standards. The idea behind that study was relatively simple: expose rats to microwave radiation similar to that emitted by cell phones, then examine their brain cells to see if any DNA damage resulted.
The news was apparently unwelcome in some quarters.
According to internal documents that later came to light, Motorola started working behind the scenes to minimize any damage Lai's research might cause even before the study was released. In a memo and a draft position paper dated Dec. 13, 1994, officials talked about how they had "war-gamed the Lai-Singh issue" and were in the process of lining up experts who would be willing to point out weaknesses in Lai's study and reassure the public.
To this day, the cell phone industry continues to dispute Lai and Singh's findings although half of about 200 studies say there is a biological effect from cell phone radiation.

As a result the embryo mortality rate in the incubation period increased to 75% (versus 16% in control group). PMID: 14658287 [PubMed - indexed for MEDLINE
Russia has long had LOWER emission requirements than Western countries. Russian scientists are not stupid. See: http://www.gallawa.com/microtech/Ch3.html Quote from this site: "Rather than concentrating on the effects of high-intensity levels, 'Soviet scientists were focusing their efforts on the lesser-known effects of prolonged or repeated exposure to low levels of microwaves. Their research, which began quite some time before that of their Western counterparts, has yielded some rather unsettling reports. Soviet studies show that long-term exposure to low levels of microwave energy could result in unpleasant effects that are not attributable to over-heating (or thermal effect) alone. These effects could be seen at exposure levels at and below 10mw/cm2, which is the occupational safety standard in the U.S. The USSR, and other European countries, has thus set their own strict guidelines for microwave safety, concluding that Western safety standards are simply not safe. For example, Russian workers are required to wear protective goggles any time they are temporarily exposed to a microwave radiation level of 1mw/cm2, a level routinely allowed to leak (although in recent years, rarely does) from U.S. microwave ovens." Personally I think the Russians know a lot we don't....
Proteins and enzymes, and probably even DNA (IANABC) rely heavily on steric (shape) effects to do their work. Why cannot microwaves cause a molecule to flip and turn into a stereoisomer of itself ?
Consider the horrors of, for example, prions such as those that cause CJD. Here is an example of a simple stereoisomer of a protein, wreaking havoc by its mere presence causing the production of more of the wrong stereoisomer.
So, Maybe if microwave radiation does not affect DNA, what about the proteins found around it that function to repair and monitor damage ? How about turning them into stereoisomers and stopping them from functioning ?
Be careful: Some headsets are used as antennas for the cell phone. That would contradict the goal you are trying to achieve.
Actually, apparently all headset wires will act as an antenna for cell phone signals, even in models where that's not part of the designed functionality. Studies have shown that using a wired headset can increase your exposure to cell phone radiation by up to 3X. However, clipping a ferrite bead on the wire is suffcient to dampen radio coming off it to negligible levels. These beads are really easy to find online.
Perhaps a bluetooth headset can minimize the energy which your DNA in the brain has to absorb.
A bluetooth headset does use significantly less
power than a cell phone. I believe the SAR for a bluetooth headset is less than 0.1 W as opposed to the 0.6-1.2 W for an average digital cell phone.
