5G will pose "little or no risk" to health, experts say

There is fear for fifth generation wireless networks (5G) and some throw catastrophic messages on how they will affect humans, but a team of researchers has concluded that there are "little or no risk" of adverse effects for the Health related to exposure to radio frequency of 5G systems.

"Although we recognize gaps in the scientific literature, particularly for exposures to millimeter wave frequencies, we judge that the probability dangers for health yet unknown at exposure levels within current limits is very low, if there is one"the researchers note in a statement by the Committee on Man and Radiation (COMAR) of the Institute of Electrical and Electronic Engineers. This committee is a non-profit organization composed of physicians, biologists, epidemiologists, engineers, and physical scientists who are experts in health and safety issues related to electromagnetic fields.

The objective of this study is to counter the increase in alarmist messages on the mysterious health effects of 5G technology. "Disinformation, along with activist websites that express even more ominous consequences of 5G, ranging from induction of cancer to be responsible for the current coronavirus pandemic, has created a substantial and unnecessary public anxiety"he explains to SciTechDaily Jerrold T. Bushberg, from the Davis School of Medicine of the University of California and Vice President of COMAR.

Less contact … for non-users

5G technology is expanding worldwide to satisfy the growing demand for wireless connectivity. 5G can transmit larger amounts of data at much higher speeds compared to previous 2G to 4G systems. This is in part because 5G uses the greater bandwidth available at higher frequencies, such as the so-called millimeter wave band, which, according to the report, "will produce more ubiquitous presence of it in the environment"

Because millimeter waves do not penetrate through vegetation and building materials, as low-frequency signals do, many transmitters will be needed low power "small cell" to provide a effective indoor coverage. Some 5G systems will have "beamforming" antennas that will transmit signals to individual users as they move, which means that those who don't use them will have less exposure.

"The misinformation and the allegations that it causes cancer or is responsible for the coronavirus pandemic, have created substantial and unnecessary public anxiety about 5G"

He tissue warming is the principal potential harmful effect of exposure to radio frequency fields. However, most countries have adopted limits Exposure limits similar to those recommended by recent standards, which seek to avoid harmful effects by setting exposure limits well below the threshold at which any adverse effect on human health would be expected to occur.

In relation to this, the researchers point out that unlike low-frequency fields, millimeter waves do not penetrate beyond the outer layer of the skin, so they do not cause heating of the deeper tissues. Similarly, the introduction of 5G is unlikely to change general levels of RF exposure.

As is currently the case, most of the exhibition will be mainly due to the communication link of the own phone or other devices, not transmitting from base stations. Finally, in almost all publicly accessible locations, RF exposures from cellular base stations, including 5G stations, will remain small

There is no association

"As long as exposures remain below established guidelines, the research results to date do not support the determination that adverse health effects are associated with exposures to radio frequency, including those from 5G systems," concludes the COMAR statement. The Commission recognizes the limitations of current evidence on the possible health and safety effects of exposure to 5G and identifies the key areas in which it should be keep investigating, including high-quality studies on biological effects of millimeter waves.
