A 2018 study looked at the effects of repeated radio frequency radiation (RFR) exposures suggesting these can cause oxidative stress, neuropsychiatric effects, endocrine changes and more. RFR is created by cell phones, wifi, bluetooth, cordless phones, and other technologies. This electrical noise has impacted the nervous systems of humans and other animals that have evolved on an electrically silent planet.
Here thoughts may turn to the risks of 5G. More rigorous research is needed as the network is established concluded Dr. Kenneth Foster in a 2019 article for Scientific American.
However, in 2011 the International Agency for Research on Cancer (IARC) provided evidence on cancer risks of RF radiation. In 2017, the WHO classified RFR as a possible carcinogen.
With the global roll out of 5G, concern has grown. In 2021, the BMJ published a letter that urged caution until the safety of the radiation from the towers and phones is confirmed:
Transmitter density means greater population exposure to high levels of radio frequency electromagnetic fields.
But what is 5G?
5G is the fifth-generation technology for wireless cellular networks. A given network is distributed over land areas called "cells", each served by at least one large fixed-location transceiver (receives and transmits) which we call a tower. The network connects your wireless devices (your phone, tablet, laptop that also contain transceivers) to the internet by radio waves.
The radio waves used in 5G are called millimeter waves (mmwaves) that require boosting antennae every 100 to 300 meters: “While higher bands are faster at carrying information, there can be problems with sending over large distances. They are easily blocked by physical objects such as trees and buildings. In order to circumvent this challenge, 5G will utilize multiple input and output antennae to boost signals and capacity across the wireless network.
In humans, MM-waves have penetrating effects including impacts on the brain, producing EEG changes and other neurological/neuropsychiatric changes, increases in apparent electromagnetic hypersensitivity and produce changes on ulcers and cardiac activity.
