If you've ever wandered through a city you might have noticed tiny 5G cell towers placed on poles for street lighting. They look like small boxes, but they're actually broadcasting wireless signals from cell phone providers to your phone.

The smaller ones are being replaced by larger built cell towers. While they're not as noticeable but they can still create issues for users.
A of the FCC'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 limits of exposure are based upon scientific research that show that RF energy can cause harm to health.

The specific absorption rate (SAR) is an indication of the radiofrequency energy that is absorption by tissues. It's typically 1.6 milliwatts per kilogram spread over a kilogram of tissue.

Since 5g is able to transmit at higher frequencies and has the potential to create more energy on the skin as well as other body parts. This could lead to many potential harms, including exacerbated development of skin diseases like dermatitis, cancer of the skin and cataracts.

Due to the potential for negative effects of 5G radiation, PSU has chosen to create a general maximum power density of four MW/cm2 averaged across 1 centimeter, and not to exceed 30 minutes, for all 5G services at 3000 GHz. This localized limit is in accordance with the peak 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 cell phone, you're probably aware that a safe distance from the tower is at least 400 meters away. This is due to the power of the transmission of cell towers increases drastically the farther you are from it.

While it sounds like something that's good, the reality is that those living close to towers may actually be more prone to health issues. For instance, a study conducted in 2014 in India discovered that people who lived within 50 meters of cell towers had significantly more health complaints than those living further far from antennas.

However, this study also showed that residents who moved to areas that were further from cell towers noticed their symptoms return to normal within a couple of days. Studies have also shown that exposure to high frequencies of radiofrequency electromagnetic fields (EMFs) can lead to cancer, brain tumors and other health issues.

how to block radiation is due to the fact that RF radiation, which is utilized in wireless communications, can penetrate the human body's exterior layer, which is the skin. This is vital to be aware of because the skin acts as a barrier to protect against mechanical injury, infection from pathogenic microorganisms, as well as infiltration of toxic substances. The skin is the most important organ of the human body. It is accountable for protecting other organs.
The FCC's Minimum Exposure Thresholds for the Minimum Exposure


The FCC's Minimum Exposure Thresholds rely on numerous assumptions that are not supported by evidence from science. These include the erroneous belief that exposures to RF radiation is safe because of the minimal absorption into body (i.e. the heating of tissues).

This assumption does not take into account the greater penetration of ELF parts of the modulated RF signal and 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 consequences of RF radiation. As such, they should not be considered for health protection exposure standards.

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 spatial specific absorption rate (psSAR) which is not a sufficient dosimetric tool to determine the degree of exposure to RF radiation. Particularly how to block electromagnetic waves is inconclusive for frequencies above 6 GHz. Furthermore, psSAR has not been tested for RF radiation exposed to other environmental agents such as sunlight. The interactions of RF radiation and other agents in the environment could cause synergistic or antagonistic results. how to block electromagnetic waves would result in an increased risk of adverse health effects. For example, co-exposure to RF radiation with sunlight may raise the chance of skin cancer and exacerbate other skin conditions like acne.
