TECHNICAL MANUAL FOR RADIO-FREQUENCY RADIATION HAZARDS

Research on electromagnetic radiation from mobile phones, including 2G, 3G, 4G LTE, and 5G NR signals.
Your cell phone is likely the most significant source of EMF exposure in your daily life. Every time you make a call, send a text, or stream a video, your phone emits radiofrequency (RF) radiation in the 700 MHz to 2.7 GHz range to communicate with cell towers. This radiation doesn't stop at your phone's case-it penetrates into your body, with the strongest exposure occurring in tissues closest to the device.

The report explains that high-power VHF-UHF radiation can harm people and animals by overheating tissue. It defines radiation protection guide numbers of 10 and 1.0 milliwatts per square meter for different temperature-humidity indices. If the curves indicate a potential hazard, the actual antenna system must be analyzed with extensive near-field calculations.

The report defines microwave radiation as electromagnetic radiation covering the range between conventional radio waves and far infrared. It explains that microwave absorption in tissues depends on water content and frequency, with fat allowing deeper penetration than muscle. The report classifies biological effects into thermal, specific thermal, and non-thermal categories and notes that harmful thermal effects usually occur at power densities exceeding 100 aW/on.

This 1971 study examined the dangers of using microwave energy to warm blood for medical transfusions, focusing on risks of hemolysis (blood cell destruction) and overheating. The research investigated how microwave heating could overwhelm or damage blood components, making it unsafe for patient use.

This 1971 French study investigated whether pulsed and modulated UHF electromagnetic radiation could influence the development of Trypanosoma equiperdum infections in laboratory animals. The research examined the relationship between EMF exposure and parasitemia (parasite levels in blood), representing early work connecting electromagnetic fields to biological infection processes.

This 1971 government study measured radiofrequency and microwave radiation levels from man-made sources throughout the Washington DC area. The research documented the electromagnetic environment in the nation's capital, providing baseline measurements of RF and microwave exposure from various transmission sources. This early work helped establish understanding of urban electromagnetic pollution levels during the dawn of the wireless age.

Researchers identified three populations treated with microwave diathermy at 2450 MHz for study. A second group comprises older patients with fair to poor health receiving weekly treatments for up to two years for temporomandibular joint conditions.

Chamber length is determined by the antenna size and the highest test frequency. Chamber width must keep the angle of incidence at or below 60 degrees to maintain absorber performance. Tapered chambers can achieve better performance at lower frequencies and lower cost than rectangular chambers.
