Hi brubble1,
Radiation from Cambium radios (or any microwave radio for that matter) do have an impact on human health. However, there are strict guideliness and rules that are already defined by various regulatory bodies that Cambium complies with. Simply put, we recommend that you maintain a certain distance from a live radio/antenna. This is clearly detailed in the User Guide of the corresponding Cambium products. Simply search for "HUMAN EXPOSURE TO RADIO FREQUENCY ENERGY" in the User Guide to read more about it. The recommended minimum safe distance is in the order of tens of centimeters and therefore the guidline applies more for the installer/tower climber than the end user on the ground and/or inside the home.
Thanks,
Sriram
