If you've ever been through a city you might have noticed tiny cell towers for 5G on street light poles. They look like small boxes, but they're actually broadcasting wireless signals from cell phone providers to your phone.
These smaller towers are replacing the larger, purpose-built cell towers. Although they're not as visible, they still can create issues for users.
A FCC's Radiation Exposure Thresholds
The FCC's Radiation Exposure Thresholds determine the safe distance that one can expose to electromagnetic energy generated by wireless devices. The exposure limits are based on research that show that RF energy could be harmful to human health.
The rate of absorption called the specific absorption rate (SAR) is an indication of the radiofrequency energy that is absorbed by tissue. It's usually 1.6 milliwatts per kilogram spread over a gram of tissue.
But, since what is a safe distance from a 5g cell tower operates at higher frequencies and has the potential to create more energy on the skin and other directly-exposed body areas. This can result in various potential problems, including an increased the development of skin conditions like dermatitis, skin cancer and cataracts.
Due to the potential for negative effects of 5G radiation, PSU has chosen to create a general maximum power density of four MW/cm2 based on the average on 1cm2, and not exceeding 30 minutes for the entire 5G spectrum at 3000 GHz. This limit for localization is in line with the peak SAR that is spatially averaged at 1.6 W/kg averaged over 1 grams of tissues at six GHz.

If you've ever used a cell phone, then you've probably realized that a safe range from the tower is around 400 meters. This is because the power of transmission from the cell tower is significantly increased the further away your location from the tower.
While this sounds like an ideal idea however, those living close to towers may actually be more prone to health problems. For instance, a 2014 study in India discovered that people living within 50 meters of cell towers experienced significantly more health complaints than those who were away from the antennas.
But, the study showed that residents who moved to areas that were further from cell towers noticed their symptoms improve within a couple of days. Another study has demonstrated that exposure to extreme amounts of electromagnetic field radiofrequency (EMFs) can cause brain tumors, cancer, and other health problems.
This is because radiofrequency radiation, utilized in wireless communications, can penetrate the human body's outer layer, called the skin. This is important to understand since the skin functions as a protective barrier against mechanical injury, infection by pathogenic microorganisms, and infiltration of toxic substances. It is also the most important organ of 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 numerous assumptions that are not supported by scientific evidence. They include the incorrect belief that short-term exposures RF radiation is safe due to minimal radiation penetration in the human body (i.e., tissue heating).
This also overlooks the deeper penetration of the ELF elements of modulated radio signals and the consequences of short bursts of heat caused by RF pulses. These assumptions do not correspond with current understanding of the biological consequences of RF radiation. As such, they should not be considered for health protection exposure guidelines.
Additionally to that, ICNIRP and FCC limit its maximum levels of radiation exposure for local peak SARs based on the maximum spatial specific absorption rate (psSAR) which is an inadequate dosimetric tool for determining the level of exposure to radiofrequency radiation. Particularly the psSAR tool is not accurate for frequencies that exceed 6 GHz. Furthermore, psSAR has not been tested for RF radiation with co-exposure to other environmental agents such as sunlight. Interactions of RF radiation with other environmental agents could cause synergistic or antagonistic impacts. This could result in an increased risk of adverse health consequences. For example, exposure to RF radiation along with exposure to sunlight can raise the chance of skin cancer and exacerbate other skin conditions like acne.
