Outcome: this is a review of a research study conducted by the World Health Organization in 2011 relating to the health effects of RF emissions. The review highlights the conflict of interest that was apparent in how the research was conducted and emphasizes that it "explains why only short-term thermal effects from RF radiation are accepted as proofs of harm, and why non-thermal biological effects are ignored."
Outcome: the epidemiological studies on RF EMF exposure do not show an increased risk of brain tumors, or cancers of the head and neck region. Studies do not support an increased risk of glicoma. However, there is a possibility of an association with acoustic neuroma.
4. Assessment of the Health Effects
of Radiofrequency Electromagnetic Fields
Outcome: current research limitations have not enabled the authors to exclude all possibility of risk. However, no short or long-term adverse health risks have been recognized. It further notes that there is a substantial discrepancy between the risks recognized by health organizations compared with the risk perceived by the general population.
Outcome: it was found that 5G downlink RF fields
generate significantly higher power density (PD) and specific
absorption rate (SAR) than a current cellular system. It further states that prior research on RF exposure has only focused on uplink only due to the closer physical contact
of a transmitter to a human body.
According to the US Food and Drug Administration, while some researchers have reported on the biological changes associated with RF waves, the majority of studies fail to show an association between exposure to RF from a cell phone and health issues.
An article from Scientific American states that while some new studies show that cell phone radiation causes cancer in lab rats, there is ongoing debate regarding such effects on humans. The article further states that RF radiation has only one known biological effect: the ability to heat tissue by exciting its molecules.
