Letter on Environmental and Health Effects of Telecommunications Infrastructure
November 2020
We explain why more than 400 expert scientists and numerous medical professionals are calling for
a halt to 5G and for the immediate reductions in both public exposure to microwave wireless radiation and
the densification of wireless infrastructure.
September 2020
“Expanding wireless communications in parks will irrevocably impair the wilderness experience. With the science on our side, we firmly believe there are wired solutions that would be far less damaging.”
April 6, 2020
The assumption that all wireless technology is safe has been shown to be incorrect. EHT strongly opposes the
widespread installation of new wireless antennas and 5G infrastructure until more testing has been done and joins
hundreds of scientific experts from around the world to urge nations to support safer technology instead of wireless
5th generation.
Letter to the Hon’ble Mr. Justice Sharad Arvind Bobde Supreme Court of India
March 3, 2020
In light of the growing demonstrations of the biological impact of RF, it is imperative that new infrastructure and 5G not be widely introduced into commerce at this time. The country needs to critically consider the impact of unprecedented increased wireless exposures to the population, insist on technological safeguards, and commit to fiberoptic cables (rather than to increased wireless radiation) as a means of improving connectivity.
Letter to Guernsey Competition and Regulatory Authority, 5G Spectrum: Draft Statement of Intent.
June 14, 2019
Technological progress does not require this increase in radiation. Wired systems are the safer, healthier alternative to wireless systems, as they do not emit harmful radiofrequency radiation. They are also more energy efficient, cost-effective, and more reliable.
The 5G rollout will dramatically increase the levels of radiofrequency radiation, a pollutant with documented harms to human health and the environment.
Teton County Wyoming, Comment on County Regs Re: “5G densification.”
May 31, 2019
Letter to inform Teton County of the scientific grounds that are the basis for hundreds of scientists calling for a moratorium on 5G and the rollout of 4G “small cells”.
FCC limits for Wireless radiation are over twenty years old. The EPA was defunded from developing proper safety standards. Instead, the FCC adopted industry-friendly guidelines from industry filled and industry loyal groups. Today the world looks quite different and the way we use cell phones and wireless devices has drastically changed.
