If you've ever walked through a city, you may have seen tiny cell towers for 5G on the poles of street lights. They appear like tiny boxes, but they're actually broadcasting wireless signals from cell phone providers to your phone.
The smaller ones are being replaced by larger built cell towers. Although they're not as visible but they can still cause issues for users.
A FCC's Radiation Exposure Thresholds
The FCC's Radiation Exposure Thresholds establish the maximum amount of time a person can be exposed to electromagnetic radiation from wireless devices. The limits for exposure are based upon scientific research which show that the energy of RF could be harmful to human health.
The absorption rate specific (SAR) is an indication of the radiofrequency energy absorbed by tissue. It is typically 1.6 Watts per kilogram averaged over one Gram of tissue.
But, since 5g operates at higher frequencies this could be able to increase the intensity of energy on the skin and other exposed body areas. This could lead to a wide range of potential harms, including exacerbated development of skin diseases such as dermatitis and skin cancer and cataracts.
Due to the possible harmful effects of radiation from 5G, PSU has chosen to establish a general, localized maximum power density of four mW/cm2 measured on 1cm2, and never to exceed 30 minutes, for the entire 5G spectrum at 3000 GHz. This localized limit is consistent with the maximum spatial-average SAR of 1.6 W/kg, averaged over one 5 grams of body tissue, at 6 GHz.
The FCC's Maximum Exposure Thresholds for Maximum Exposure
If you've ever used a cell phone, you probably know that the safest distance from the tower should be at least 400 meters. This is because the power of transmission from cell towers increases drastically the further away you are from it.
While safe distance from cell tower sounds like something that's good but the truth is that people who live close to towers may actually be more susceptible to health issues. For https://www.openlearning.com/u/vargasdelgado-rtp3p0/blog/VeryBestMinimumAcceptableLengthBetweenYourselfPlusA5GMobileTowerSystem , a 2014 study in India discovered that people living within 50 meters of cell towers had much more health problems than those who lived farther far from antennas.
This study found that people who moved to areas further away from cell towers noticed their symptoms improve within a few days. Another study has revealed that exposure to high frequencies of radiofrequency electromagnetic fields (EMFs) could cause cancer, brain tumors and other health issues.
This is due to the fact that radiofrequency radiation, used in wireless communications, may penetrate the human body's outer layer, the skin. This is important to understand because the skin acts as a barrier to protect against mechanical injury, infection caused by pathogenic microorganisms and entry of toxic substances. The skin is the most important organ in the human body and is responsible for keeping the integrity of the other organs.
The FCC's Minimum Exposure Thresholds
The FCC's Minimum Exposure Thresholds are based on a variety of assumptions that aren't supported by evidence from science. These include the erroneous assumption that short-term exposures to RF radiation are safe due to minimal absorption into body (i.e. thermal heating of tissue).
The assumption also ignores the more extensive penetration of ELF components of modulated RF signals as well as the consequences of short bursts of heat from pulsed RF waves. These assumptions do not correspond with current understanding of the biological consequences of RF radiation, and thus they should not be relied upon for health-protection exposure guidelines.
Additionally to that, ICNIRP and FCC limit their maximum radiation limits for local peak SARs that are based on the peak spatial specific absorption rate (psSAR) which is not a sufficient dosimetric tool to assess the amount of exposure to RF radiation. Particularly what is a safe distance from a 5g cell tower is inconclusive for frequencies above 6 GHz. In addition, psSAR is not been evaluated for RF radiation exposed to other agents of the environment such like sunlight. The interactions of RF radiation with other environmental agents may produce synergistic or antagonistic effects. This can lead to an increased risk of adverse health effects. For example, co-exposure to RF radiation and sunlight could raise the chance of skin cancer and exacerbate other skin disorders, such as acne.
