Looking for That Wi-Fi, Bad Behavior Link

Some consumer groups in the United Kingdom are concerned that Wi-Fi signals may be harmful to young children and have convinced the a U.K. public health advisor to take on a $600,000 study to determine if the signals can harm health, according to an article posted by telegraph.co.uk. The groups are concerned that Wi-Fi signals, which "are very low power, typically 0.1 watt in both the computer and the router," according to the article, could affect children in classrooms where the Wi-Fi signals are emitted to experience "fatigue, memory and concentration problems, irritability and bad behaviour." And that would be different from . . . ?
