What is the safest distance coming from a 5G cell Tower?

If you've ever wandered through a city, you may have seen tiny mini 5G cell towers on street light poles. They look like small boxes however they're actually sending wireless signals from cell phone providers to your phone.

These smaller towers are replacing larger, purpose-built cell towers. While they're not as noticeable, they still can cause issues for users.
It is the of the FCC's Radiation Exposure Thresholds

The FCC's Radiation Exposure Thresholds determine the maximum amount of time one can expose to electromagnetic radiation from wireless devices. The limits for exposure are based on scientific data that prove that electromagnetic energy could cause harm to health.

is 5g harmful for humans and the environment  (SAR) is a measure of the amount of radiofrequency energy that is absorbed by tissue. It is typically 1.6 milliwatts per kilogram calculated over one Gram of tissue.

Since 5g is able to transmit at higher frequencies, it has the potential to increase the intensity of energy on the skin and other exposed body areas. This could result in various possible harms, like the formation of skin disorders such as dermatitis and skin cancer and cataracts.

Because of the potentially severe effects of  5g radiation , PSU has chosen to set a general localized limits on power density, which is 4mW/cm2 averaged on 1cm2, and not to exceed 30 minutes, for all 5G services running at 3000 GHz. This localized limit is in accordance with the maximum SAR spatial-average of 1.6 W/kg averaged over 1 grams of tissues at six GHz.
The FCC's Maximum Exposure Thresholds for Maximum Exposure

If you've ever used a mobile phone, you're probably aware that a safe range from the tower is at least 400 meters. This is because the power of the transmission of cell towers increases drastically the farther you are from it.

While this sounds like a good idea however, people who live close to towers could be more prone to health issues. For instance, a 2014 study in India discovered that those living within 50 meters of cell towers had significant more health issues than those living further distance from them.

This study revealed that those who relocated to areas that were further from the cell towers saw their symptoms return to normal within a few days. Another study has shown that exposure to high amounts of electromagnetic field radiofrequency (EMFs) could cause brain tumors, cancers and other health issues.

This is due to the fact that RF radiation, used in wireless communications, may penetrate the body's outer layer, which is the skin. This is important to understand since the skin functions as a protective barrier against injuries caused by mechanical forces, infections from pathogenic microorganisms, as well as entry of toxic substances. It is also the most important organ of the human body. It is accountable for maintaining the integrity of other organs.
The FCC's Minimum Exposure Thresholds for the Minimum Exposure

The FCC's Minimum Exposition Thresholds depend on numerous assumptions that aren't supported by evidence from science. These include the erroneous assumption that short-term exposures to RF radiation are safe due to minimal penetration into the body (i.e., tissue heating).

The assumption is also ignoring the deeper penetration of the ELF elements of modulated radio signals and the consequences of short bursts of heat generated by RF waves that are pulsed. These assumptions are not in line with the current understanding of biological consequences of RF radiation. As such, they should not be considered for health protection exposure standards.

Furthermore, the ICNIRP and FCC restrict their maximum exposure limits to local peak SARs, based on the peak speed of spatial absorption (psSAR), which can be described as not a sufficient dosimetric tool for determining the level of exposure to RF radiation. In particular the psSAR tool is not accurate for frequencies above 6 GHz. In addition, psSAR is not been evaluated for RF radiation with co-exposure to other environmental agents , such as sunlight. Interactions of RF radiations with different environmental agents could produce synergistic or antagonistic impacts. This could result in an increased risk of adverse health consequences. For example, co-exposure to RF radiation along with exposure to sunlight can increase the risk of skin cancer and exacerbate other skin disorders, such as acne.
