If you've ever walked through a city and spotted tiny mini 5G cell towers on the poles of street lights. They appear like tiny boxes however they're actually sending wireless signals from cellular providers to your phone.
The smaller ones are being replaced by larger built cell towers. Although they're not as visible, they still can cause issues for users.
It is the FCC's Radiation Exposure Thresholds

The FCC's Radiation Exposure Thresholds determine the safe limit at which a person can be exposed to electromagnetic energy generated by wireless devices. The exposure limits are based upon scientific research that show that RF energy can be harmful to human health.
The specific absorption rate (SAR) is an indication of the amount of radiofrequency energy that is taken up by tissues. It is typically 1.6 Watts per kilogram spread over a Gram of tissue.
But, since 5g operates at higher frequencies, it has the potential to cause greater energy intensity on the skin as well as other body areas. This can lead to many possible harms, like the appearance of skin conditions like dermatitis, cataracts, and skin cancer.
Due to the possible severe effects of 5g radiation, PSU has chosen to create a general maximum power density of four mW/cm2 based on the average over 1 cm2, but not to exceed 30 minutes, for all 5G services at 3000 GHz. This limit for localization is in line with the peak 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
If you've ever used a mobile phone, you're probably aware that a safe location from the tower should be at least 400 meters. This is due to the transmitting power of cell towers increases drastically the further away the tower is.
While this sounds like a good idea but the truth is that people living in close proximity to towers could be more vulnerable to health problems. For cell phone radiation , a 2014 study in India discovered that people who lived within 50 meters of cell towers had much more health problems than those who were distance from them.
This study revealed that those who relocated to areas further away from the cell towers saw their symptoms return to normal within a couple of days. Another study has demonstrated that exposure to extreme amounts of electromagnetic field radiofrequency (EMFs) can cause brain tumors, cancers as well as other health issues.
radiation from cell phones is due to the fact that RF radiation, which is used in wireless communications, may penetrate the body's outer layer, which is the skin. It is crucial to know because the skin acts as a shield against mechanical injury, infection from pathogenic microorganisms, as well as infiltration of toxic substances. It is also the biggest organ in the human body, and is accountable for keeping the integrity of the other organs.
The FCC's Minimum Exposure Thresholds for the Minimum Exposure
The FCC's Minimum Exposure Thresholds rely on several assumptions that aren't supported by scientific research. This includes the false assumption that exposures of a short duration to RF radiation are safe due to the limited radiation penetration in the human body (i.e. the heating of tissues).
The assumption also ignores the greater penetration of ELF components of modulated RF signals, as well as the effects of short bursts of heat caused by RF pulses. These assumptions are not in line with current knowledge of the biological consequences of RF radiation. As such they should not be relied upon for health-protection exposure standards.
In addition there is the fact that both ICNIRP and FCC limit their maximum exposure limits to local peak SARs based on the peak frequency of absorption (psSAR), which can be described as not a reliable dosimetric instrument to determine the degree of exposure to RF radiation. In particular it is inconclusive for frequencies that exceed 6 GHz. Furthermore, psSAR has not been tested for RF radiation exposed to other environmental agents , such as sunlight. The interactions of RF radiations with different agents in the environment could cause synergistic or antagonistic effects. This would result in an increased risk of adverse health effects. For instance, exposure to RF radiation with sunlight may cause an increase in the incidence of skin cancer, and may also exacerbate other skin disorders, such as acne.
