More than 180 scientists and doctors from 35 countries recommend a moratorium on the roll-out of the fifth generation, 5G, for telecommunication until potential hazards for human health and the environment have been fully investigated by scientists independent from industry. 5G will substantially increase exposure to radio-frequency electromagnetic fields (RF-EMF) on top of the 2G,3G, 4G, WiFi, for telecommunications already in place. RF-EMF has been proven to be harmful for humans and the environment.
