1. Do wireless phones pose a health
hazard?
The available scientific evidence does
not show that any health problems are
associated with using wireless phones.
There is no proof, however, that wireless
phones are absolutely safe. Wireless
phones emit low levels of radiofrequency
energy (RF) in the microwave range while
being used.
