If you've ever been through a town you might have noticed tiny 5G cell towers placed on poles for street lighting. They appear like tiny boxes however they're actually sending wireless signals from mobile providers to your phone. 
 
what is a safe distance from a 5g cell tower are being replaced by larger built cell towers. While they're less noticeable however, they could cause issues for users. 
It is the Federal Communications Commission's Radiation Exposure Thresholds 
 
The FCC's Radiation Exposure Thresholds define the safe limit at which a person can be exposed to electromagnetic energy generated by wireless devices. The exposure limits are based on scientific data which show that the energy of RF can cause harm to health. 
 
The absorption rate specific (SAR) is an indicator of the amount of radiofrequency energy absorbed by tissue. https://notes.io/qNCFa 's usually 1.6 watts per kilogram, spread over a Gram of tissue. 
 
But, since 5g operates at higher frequencies this could be able to cause greater energy intensity on the skin and other exposed body parts. This could lead to various possible harms, like the appearance of skin conditions such as dermatitis, cataracts, and skin cancer. 
 
Because of the potentially negative effects of 5G radiation, PSU has chosen to establish a general, localized limits on power density, which is 4mW/cm2 based on the average across 1 centimeter, and not to exceed 30 minutes for all 5G services at 3000 GHz. This localized limit is in accordance with the highest SAR that is spatially averaged at 1.6 W/kg, averaged over one g of tissue at 6 GHz. 
The FCC's Maximum Exposure Thresholds 
 
If you've ever used a cell phone, you probably know that the safest distance from the tower should be at least 400 meters away. what is a safe distance from a cell tower is due to the power of transmission from the cell tower is significantly increased the farther you are from it. 
 
While this sounds like a good idea but the truth is that people who live close to towers might be more prone to health issues. For example, a study from 2014 in India found that residents who lived within 50m of cell towers experienced significantly more health complaints than those living further distance from them. 
 
 
But, the study found that people who moved to areas that were further from the cell towers saw their symptoms improve within a few days. Another study has revealed that exposure to high levels of radiofrequency electromagnetic fields (EMFs) can cause brain tumors, cancer and other health issues. 
 
This is due to the fact that RF radiation, which is utilized in wireless communication, can penetrate the body's outer layer, which is the skin. It is crucial to know because the skin acts as a shield against injuries caused by mechanical forces, infections by pathogenic microorganisms, and entry of toxic substances. The skin is the biggest organ in the human body. It is responsible for maintaining the integrity of other organs. 
The FCC's Minimum Exposure Thresholds 
 
The FCC's Minimum Exposition Thresholds depend on a variety of assumptions that aren't supported by scientific evidence. They include the false belief that exposures to RF radiation are safe because of the minimal radiation penetration in the human body (i.e. thermal heating of tissue). 
 
This assumption does not take into account the more extensive penetration of ELF parts of modulated RF signals as well as the effect of brief bursts of heat caused by RF pulses. These assumptions do not correspond with current understanding of the biological consequences of RF radiation, and thus they should not be considered for health protection exposure standards. 
 
Additionally to that, ICNIRP and FCC restrict their limit of exposure to the local SARs, based on the maximum frequency of absorption (psSAR) that is not a sufficient dosimetric tool for determining the level of exposure to RF radiation. Particularly the psSAR tool is not accurate for frequencies above 6 GHz. Additionally, psSAR hasn't been evaluated for RF radiation with co-exposure to other environmental agents such like sunlight. The interactions of RF radiation and other agents in the environment could cause synergistic or antagonistic effects. This would result in an increased risk of negative health adverse effects. For instance, exposure to RF radiation with sunlight may raise the chance of developing skin cancer, and may also exacerbate other skin disorders, such as acne.
