Answer: No. Mobile phones do not give off sub-atomic (ionizing)  radiation.    Answer: Yes.

not a techie-but think that's right). It worked great with my iPhone-but doesn't seem to do much for my new Galaxy-I tried resetting the wireless booster-and I also downloaded a signal booster app on the phone-still seems to only show 1-2 bars-with spikes to full bars sporadically-then back to 1-2 bars. Post(s). That is incorrect, higher numbers mean a better signal. -70 is 10 times stronger than -80 Firstly, remove any signal booster apps, they are all nonsense. Secondly, in the -70 to -80 dBm range you should be getting 5 bars easily. I'm at home on LTE with -94 dBm and I'm at 4 bars.
