Are usually safest distance from the 5G cell System?

If you've ever walked through a town you might have noticed tiny mini 5G cell towers placed on poles for street lighting. They appear like tiny boxes however they're actually sending wireless signals from cellular providers to your phone.

These smaller towers are replacing larger built cell towers. While they're less noticeable, they still can cause problems for people.
It is the Federal Communications Commission's Radiation Exposure Thresholds

The FCC's Radiation Exposure Thresholds define the maximum amount of time an individual can be exposed to electromagnetic energy generated by wireless devices. The exposure limits are based on scientific data that show that RF energy can cause harm to health.

The specific absorption rate (SAR) is an indicator of the amount of radiofrequency energy that is absorption by tissues. It is typically 1.6 Watts per kilogram spread over a gram of tissue.

However, because 5g transmits at higher frequencies and has the potential to increase the intensity of energy on the skin as well as other body parts. This could lead to various possible harms, like the formation of skin disorders like dermatitis, cataracts and skin cancer.

Due to the possible severe effects of 5g radiation, PSU has chosen to set a general localized power density limit of 4 mW/cm2 measured over 1 cm2, and not exceeding 30 minutes for the entire 5G spectrum at 3000 GHz. This limit for localization is in line with the highest SAR spatial-average of 1.6 W/kg, averaged over one 5 grams of body tissue, at 6 GHz.
The FCC's Maximum Exposure Thresholds for Maximum Exposure

If you've ever used a mobile phone, then you're aware that the safest distance from the tower is at least 400 meters. This is due to the power of the transmission of cell towers increases drastically the further away you are from it.

While  how far do cell phone towers reach  sounds like an ideal idea however, people living in close proximity to towers could be more susceptible to health problems. For example, a study from 2014 in India discovered that those who lived within 50m of cell towers had significantly more health complaints than those who were away from the antennas.

This study showed that residents who moved into areas farther away from the cell towers saw their symptoms improve within a few days. Another study has demonstrated that exposure to extreme amounts of electromagnetic field radiofrequency (EMFs) could cause brain tumors, cancer, and other health problems.

This is because RF radiation, which is used in wireless communication, can penetrate the body's outer layer, the skin. This is important to understand because the skin acts as a barrier to protect against injury to the body, infection from pathogenic microorganisms, as well as entry of toxic 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

The FCC's Minimum Exposure Thresholds rely on numerous assumptions that are not supported by scientific research. They include the false belief that exposures to RF radiation are safe due to minimal absorption into body (i.e., tissue heating).

The assumption is also ignoring the greater penetration of ELF components of modulated RF signals and the effects of brief bursts of heat generated by RF waves that are pulsed. These assumptions are not in line with current knowledge of the biological effects of RF radiation. As such they should not be considered for health protection exposure guidelines.

Additionally, the ICNIRP and FCC restrict their maximum limit of exposure to the local SARs that are based on the maximum spatial specific absorption rate (psSAR) which is not a reliable dosimetric instrument to assess the amount of radiation exposure. Particularly it is inconclusive for frequencies that exceed 6 GHz. Furthermore, psSAR has not been evaluated for RF radiation with co-exposure to other environmental agents such like sunlight. In the event of interactions, RF radiations with different agents in the environment could result in antagonistic or synergistic effects. This could result in the risk of having adverse health effects. For example, co-exposure to RF radiation along with exposure to sunlight can increase the risk of developing skin cancer and exacerbate other skin diseases such as acne.
