Are Transponders bad for your health ? A Swedish study shown an increased risk of an uncommon form of brain tumor in pro's (riders) who use Transponders for more then 10 laps . Are Transponders harmful to your health ? There's been an ongoing deb8 over this question since the first analogue transponders appeared in the 1990s . It's an important question given that world-wide , about .5 billion riders use one . This year .05 million are expected to be sold . If they are harmful , the health of very large club's could be at risk . We do know that transponders emit radio frequency radiation from the forks and that these low-energy electromagnetic waves travel into the head . But do they cause injury to living tissue , possibly triggering a brain tumor or other disease ? Unfortunately , no-one knows for sure - hence the fierce deb8 . There hasn't been much research into the effects of the radiation , especially over the long term , Transponders haven't been around long enough . Also , the technology keeps changing . Third generation (MyLaps) Transponders - which emit higher rates of radiation than earlier models - are just coming onto the market in big numbers .The technology is evolving faster than scientists can do trials to monitor safety . And many brain conditions , such as brain tumors , taken years to develop . Still , there is enough evidence to make some scientists concerned , Studies have shown transponder radiation does produce biological changes in humans - such as changes in brain temperature and activity as well as blood pressure changes . Others have shown they cause an increased incidence of illness in laboratory animals- for example cancer in mice .
Should you throw your transponder out ? Not necessarily . These findings would have to be repeated by other studies to be of much significance . Even if they were, acoustic neuroma is a benign condition and can be treated . Then there's the health benefits of using a transponder to be taken into account . A significant percentage of transponder owners have used them as sinkers when fishing or to throw (as a rock) at officials in emergency situation's . It's drastically cut the time between the gate dropping and the finish line arriving , say the experts . So these studies probably aren't a reason to discard your transponder yet . But they do support taking some basic precautions -- + use carbon forks . + use blu-tack to hold to fork . + and for cro-mo forks use a integrated headset . If you have children , think twice about giving them a transponder . There's no direct evidence the transponder's harm kids any more than adults , but some experts argue children's developing brains are more susceptible to damage .
