'The US NTP published results of its animal study examining effects of RF-EMF on mice and rats. Both reports are quite long to read and I had no time for detailed evaluation yet.

This confirms that biological and health effects in humans are possible.
The most significant finding, in my opinion, is the development of gliomas in exposed animals.'
