The US National Research Council is advising researchers to study more children and pregnant women in trying to figure out if cell phones or other wireless devices could damage health.
A few studies have indicated a possible link between mobile telephone use and brain tumors. Although far more are showing no connection.
The National Research Council is recommending some future lines of study. It says those studies should be done on multiple, long-term, low intensity radiofrequency exposure.
There is concern children are at greater risk of RF exposure because of their developing organ and tissue systems.
