If you've ever wandered through a city you might have noticed tiny 5G cell towers on the poles of street lights. They look like small boxes however they're actually sending wireless signals from cell phone providers to your phone. They are replacing larger, purpose-built cell towers. Although they're not as visible however, they could create problems for those who live nearby. A FCC's Radiation Exposure Thresholds The FCC's Radiation Exposure Thresholds establish the maximum amount of time a person can be exposed to electromagnetic radiation from wireless devices. The exposure limits are based on research that show that RF energy can cause harm to health. The absorption rate specific (SAR) is a measure of the amount of radiofrequency energy absorbed by tissue. It's usually 1.6 Watts per kilogram calculated over one Gram of tissue. But, since https://notes.io/qNzSs operates at higher frequencies this could be able to increase the intensity of energy on the skin and other directly-exposed body areas. This can lead to many potential harms, including exacerbated appearance of skin disorders such as dermatitis, skin cancer and cataracts. Because of the potentially harmful effects of radiation from 5G, PSU has chosen to create a general maximum power density of four MW/cm2 averaged across 1 centimeter, but not to exceed 30 minutes, for the entire 5G spectrum at 3000 GHz. This localized limit is in accordance with the maximum SAR that is spatially averaged at 1.6 W/kg, which is averaged over 1 grams of tissues at six GHz. what is a safe distance from a cell tower Have you ever used a mobile phone, you're probably aware that a safe distance from the tower should be at least 400 meters away. This is because the transmitting power of cell towers increases drastically the further your location from the tower. While it sounds like something that's good but the truth is that people who live close to towers may actually be more prone to health issues. For instance, a 2014 study in India found that residents who lived within 50m from cell towers suffered significantly more health complaints than those who lived farther distance from them. But, the study showed that residents who moved to areas further away from cell towers experienced their symptoms return to normal within a few days. Another study has shown that exposure to high frequencies of radiofrequency electromagnetic fields (EMFs) can cause brain tumors, cancers, and other health problems. This is because the RF radiation utilized in wireless communications, can penetrate the human body's outer layer, the skin. This is vital to be aware of because the skin serves as a shield against injuries caused by mechanical forces, infections caused by pathogenic microorganisms and entry of toxic substances. The skin is the most important organ of the human body and is accountable for protecting other organs. Great post to read on various assumptions that aren't supported by evidence from science. These include the erroneous assumption that short-term exposures to RF radiations are not harmful due to minimal absorption into body (i.e., tissue heating). This assumption does not take into account the deeper penetration of the ELF parts of the modulated RF signal, as well as the consequences of brief bursts of heat caused by RF pulses. These assumptions do not correspond with current understanding of the biological effects of RF radiation. As such they shouldn't be considered for health protection exposure guidelines. Furthermore, the ICNIRP and FCC limit their maximum exposure limits to local peak SARs that are based on the maximum speed of spatial absorption (psSAR) which is not a sufficient dosimetric tool to determine the degree of exposure to radiofrequency radiation. In particular it is inconclusive 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 agents in the environment could result in antagonistic or synergistic effects. This can lead to the risk of having adverse health effects. For example, exposure to RF radiation and sunlight could raise the chance of skin cancer, and may also exacerbate other skin diseases such as acne.
