If you've ever been through a town you might have noticed tiny mini 5G cell towers on street light poles. cell phone radiation look like little boxes however they're actually sending wireless signals from cell phone providers to your phone.

They are replacing the larger, purpose-built cell towers. Although they're not as visible but they can still create issues for users.
The Federal Communications Commission's Radiation Exposure Thresholds
The FCC's Radiation Exposure Thresholds establish the safe limit at which an individual can be exposed to electromagnetic radiation from wireless devices. The limits of exposure are based on research which prove that electromagnetic energy could be harmful to human health.
The specific absorption rate (SAR) is a measure of the amount of radiofrequency energy that is absorption by tissues. It is typically 1.6 Watts per kilogram averaged over one Gram of tissue.
Since 5g is able to transmit at higher frequencies, it has the potential to create more energy on the skin as well as other body parts. This can lead to a wide range of potential harms, including exacerbated appearance of skin disorders like dermatitis, cancer of the skin and cataracts.
Because of the potentially severe effects of 5g radiation, PSU has chosen to set a general localized power density limit of 4 mW/cm2 measured across 1 centimeter, and not to exceed 30 minutes, for all 5G services at 3000 GHz. This localized limit is in accordance with the maximum SAR that is spatially averaged at 1.6 W/kg, which is averaged over 1 g of tissue at 6 GHz.
The FCC's Maximum Exposure Thresholds for Maximum Exposure
In the event that you've used mobile phone, then you've probably realized that a safe location from the tower is at least 400 meters away. This is because the transmitting power of cell towers increases drastically the further your location from the tower.
While this sounds like something that's good however, those living close to towers may actually be more susceptible to health issues. For instance, a 2014 study in India discovered that people who lived within 50m of cell towers had significant more health issues than those who lived farther distance from them.
This study showed that residents who moved into areas farther away from the cell towers saw their symptoms return to normal within a couple of days. Studies have also demonstrated that exposure to extreme levels of radiofrequency electromagnetic fields (EMFs) could cause cancer, brain tumors and other health issues.
This is due to the fact that radiofrequency radiation, utilized in wireless communications, can penetrate the human body's outer layer, called the skin. This is important to understand because the skin serves as a protective barrier against injuries caused by mechanical forces, infections from pathogenic microorganisms, as well as entry of toxic substances. Additionally, it is the biggest organ in the human body. It is responsible for keeping the integrity of other organs.
The FCC's Minimum Exposure Thresholds
The FCC's Minimum Exposure Thresholds rely on various assumptions that aren't supported by scientific evidence. Look at more info include the erroneous belief that short-term exposures RF radiation are safe due to minimal radiation penetration in the human body (i.e., tissue heating).
This assumption does not take into account the greater penetration of ELF parts of the modulated RF signal, as well as the effect of brief bursts of heat from pulsed RF waves. These assumptions do not correspond with the current understanding of biological consequences of RF radiation. Therefore, they should not be used for health protective exposure guidelines.
Additionally there is the fact that both ICNIRP and FCC are limiting their maximum exposure limits to local peak SARs based on the maximum frequency of absorption (psSAR) that is not a sufficient dosimetric tool to assess the amount of exposure to radiofrequency radiation. In particular the psSAR tool is not accurate for frequencies that exceed 6 GHz. In addition, psSAR is not been tested for RF radiation with co-exposure to other environmental agents such as sunlight. The interactions of RF radiation and other environmental agents could result in antagonistic or synergistic effects. This would result in the risk of having adverse health effects. For example, exposure to RF radiation along with exposure to sunlight can increase the risk of skin cancer and exacerbate other skin conditions like acne.
