My company - 9CI - recently measured common RF sources in the home.
Modern cars also have multiple RF transmitters in them - Bluetooth, key transponders, WiFi, etc.
The FCC's approach to 5G is a supply/demand one. Three is huge demand for high speed data links to mobile device, and their job is to meet that demand by allocating and providing "spectrum" to providers. The demand comes from consumers/customers. All market driven.
There are, however, possible externalities. Un-priced long term costs. Health effects are one of these possible externalities.
Wireless technology appears to be on a similar path to tobacco with regards to long term health effects, who bears the cost and suffering of these effects, and who is legally protected from liability. This separation of liability from the product has created an incentive for wireless providers and device manufactures to get as much as they can as quickly as they can get it. High time preference.
Because manufacturers are free of liability, there is no market incentive for them to study the health effects of prolonged exposure to microwave and millimeter-wave radiation on 5G devices (as well as 4G/LTE, 3G, 2G, GSM, WiFi, Bluetooth, etc).
An excellent documentary on the health effects of RF radiation is Generation Zapped, available on Amazon or the iTunes store.
You as an individual can make informed decisions and take your health and well being into your own hands. With a small amount of effort, you can protect yourself from sources of RF radiation in your living space and work space.
My company - 9CI - designs and manufactures the Safe and Sound line of RF detectors - simple to use, highly accurate detectors and meters. We have partnered with Safe Living Technologies to produce these meters entirely in North America so that the general public has a laboratory tested and calibrated tool for detecting sources of electromagnetic radiation in their living and work spaces.
Once these sources have been identified, Safe Living Technologies offers products to protect your space, including shielding paints, fabrics, and construction materials to be used during new construction and renovation.
There's no need to complain or feel powerless about these new technologies. You can easily identify them with an RF detector or meter, and you can protect yourself from their negative health effects in many simple and cost-effective ways.
