If you've ever walked through a city and spotted tiny mini 5G cell towers on street light poles. cell phone radiation look like little boxes, but they're actually broadcasting wireless signals from mobile providers to your mobile.
They are replacing larger built cell towers. While they're less noticeable, they still can create issues for users.

It is the of the FCC's Radiation Exposure Thresholds
The FCC's Radiation Exposure Thresholds determine the safe limit at which one can expose to electromagnetic energy generated by wireless devices. The limits for exposure are based upon scientific research which show that the energy of RF can cause harm to health.
The absorption rate specific (SAR) is an indication of the amount of radiofrequency energy taken up by tissues. It's usually 1.6 Watts per kilogram calculated over one gram of tissue.
However, because 5g transmits at higher frequencies and has the potential to cause greater energy intensity on the skin and other exposed body areas. This can result in many potential problems, including an increased the development of skin conditions like dermatitis, skin cancer and cataracts.
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, and not to exceed 30 minutes for all 5G services running at 3000 GHz. This limit for localization is in line with the peak 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
If you've ever used a cell phone, then you've probably realized that the safest location from the tower is at least 400 meters away. This is due to the power of the transmission of a cell tower increases dramatically the further the tower is.
While this sounds like an ideal idea however, people living in close proximity to towers might be more susceptible to health issues. For instance, a study conducted in 2014 in India found that residents who lived within 50m of cell towers had much more health problems than those living further far from antennas.
But, the study revealed that those who relocated to areas that were further from the cell towers saw their symptoms improve within a couple of days. Another study has demonstrated that exposure to extreme levels of radiofrequency electromagnetic fields (EMFs) can cause cancer, brain tumors, and other health problems.
This is because radiofrequency radiation, utilized in wireless communications, can penetrate the human body's outer layer, the skin. This is important to understand because the skin serves as a barrier to protect against injuries caused by mechanical forces, infections from pathogenic microorganisms, as well as the entry of harmful substances. It is also the most important organ of the human body and is responsible for maintaining the integrity of other organs.
The FCC's Minimum Exposure Thresholds for the Minimum Exposure
The FCC's Minimum Exposure Thresholds are based on many assumptions that aren't supported by scientific evidence. These include the erroneous belief that short-term exposures RF radiation are safe because of the minimal absorption into body (i.e. thermal heating of tissue).
This also overlooks the greater penetration of ELF elements of modulated radio signals, as well as the effects on the body of short bursts generated by RF waves that are pulsed. These assumptions are not in line with current understanding of the biological effects of RF radiation. Therefore they shouldn't be used for health protective exposure standards.
Furthermore to that, ICNIRP and FCC limit its maximum levels of radiation exposure for local peak SARs that are based on the peak frequency of absorption (psSAR), which can be described as an inadequate dosimetric tool to assess the amount of exposure to RF radiation. Particularly the psSAR tool is not accurate for frequencies above 6 GHz. Furthermore, psSAR has not been tested for RF radiation that is exposed to other environmental agents , such like sunlight. The interactions of RF radiation and other environmental agents could cause synergistic or antagonistic results. This can lead to an increased risk of negative health adverse effects. For example, exposure to RF radiation and sunlight could increase the risk of developing skin cancer, as well as aggravate other skin diseases such as acne.
