If you've ever walked through a town, you may have seen tiny cell towers for 5G on street light poles. faraday hats look like small boxes, but they're actually broadcasting wireless signals from cellular providers to your phone.
These smaller towers are replacing larger built cell towers. Although they're not as visible, they still can cause problems for people.
The of the FCC's Radiation Exposure Thresholds
The FCC's Radiation Exposure Thresholds define the safe distance that a person can be exposed to electromagnetic energy from wireless devices. The exposure limits are based on research which show that the energy of RF could cause harm to health.
The specific absorption rate (SAR) is an indication of the radiofrequency energy absorption by tissues. It's usually 1.6 Watts per kilogram calculated over one gram of tissue.
However, because 5g transmits at higher frequencies this could be able to cause greater energy intensity on the skin and other exposed body parts. This can lead to various possible harms, such as an increase in appearance of skin disorders like dermatitis, skin cancer and cataracts.
Because of the potentially severe effects of 5g radiation, PSU has chosen to establish a general, localized limits on power density, which is 4mW/cm2 based on the average on 1cm2, but not exceeding 30 minutes for all 5G services running at 3000 GHz. This localized limit is in accordance with the maximum spatial-average SAR of 1.6 W/kg averaged over 1 g of tissue at 6 GHz.
The FCC's Maximum Exposure Thresholds for Maximum Exposure
In the event that you've used mobile phone, then you've probably realized that the safest range from the tower is at least 400 meters. This is because the power of transmission from cell towers increases drastically the farther your location from the tower.
While it sounds like something that's good, the reality is that those living close to towers might be more prone to health problems. For instance, a 2014 study in India discovered that people living within 50 meters of cell towers experienced much more health problems than those who were away from the antennas.
This study showed that residents who moved to areas that were further from cell towers experienced their symptoms return to normal within a few days. Another study has demonstrated that exposure to extreme frequencies of radiofrequency electromagnetic fields (EMFs) could cause cancer, brain tumors as well as other health issues.
This is because the RF radiation used in wireless communication can be absorbed by the body's outer layer, the skin. faraday cage hat is important to understand 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 largest organ in the human body and is accountable for protecting other organs.
The FCC's Minimum Exposure Thresholds for the Minimum Exposure
The FCC's Minimum Exposure Thresholds rely on various assumptions that aren't supported by scientific evidence. These include the erroneous belief that exposures to RF radiation are safe because of the minimal absorption into body (i.e. thermal heating of tissue).
This assumption does not take into account the more extensive penetration of ELF components of modulated RF signals, as well as the effect on the body of short bursts generated by RF waves that are pulsed. These assumptions do not correspond with the current understanding of biological effects of RF radiation. As such faraday hats shouldn't be relied upon for health-protection exposure guidelines.
In addition there is the fact that both ICNIRP and FCC limit its maximum levels of radiation exposure for local peak SARs, based on the peak frequency of absorption (psSAR) that is not a reliable dosimetric instrument to determine the degree of radiation exposure. Particularly, psSAR is inaccurate when frequencies exceed 6 GHz. Additionally, psSAR hasn't been tested for RF radiation exposed to other agents of the environment such like sunlight. Interactions of RF radiations with different environmental agents may produce synergistic or antagonistic results. This would result in an increased risk of adverse health effects. For example, exposure to RF radiation along with exposure to sunlight can raise the chance of developing skin cancer and exacerbate other skin diseases such as acne.
