Researchers measured how radiofrequency radiation is absorbed by human and animal tissue models when exposed to near-field conditions (close-range exposure) versus far-field conditions. They found that near-field exposure creates different absorption patterns and potentially dangerous "hot spots" of concentrated radiation in body tissues. This matters because most of our daily EMF exposure comes from devices held close to our bodies, like cell phones.

Scientists tested microwave radiation exposure on a life-sized rhesus monkey model using 1.29 GHz radar signals to measure how energy is absorbed in body tissues. They found that while some areas showed expected surface heating, certain internal regions created dangerous 'hot spots' with three times higher energy absorption than the surface. This reveals how microwave radiation can create unpredictable heating patterns deep inside the body.

Researchers exposed E. coli bacteria to millimeter wave radiation at frequencies of 51.3-52.3 GHz (similar to some 5G frequencies) at low power levels. The study examined whether this exposure could trigger colicin production, a natural bacterial defense mechanism. The findings suggest that even low-level millimeter wave radiation can influence bacterial cellular processes.

Researchers developed a sophisticated method to expose cells to extremely high microwave radiation (320-450 mW/cm²) at 41.80 GHz and 73.95 GHz while preventing heating through rapid medium circulation. After one hour of exposure, they found no effects on cell structure or protein/RNA synthesis, suggesting thermal effects may be the primary mechanism of microwave biological impact.

Researchers used 915 MHz microwave diathermy on healthy volunteers' thigh muscles while measuring blood flow at different depths. They found blood flow increased dramatically from 2 to 32 ml/min/100g, with deeper muscle tissue showing different response patterns than surface tissue. This demonstrates how microwave energy penetrates and affects human tissue circulation.

Researchers exposed dogs' thyroid glands to 2450 MHz microwave radiation (the same frequency used in microwave ovens) and found changes in thyroxine hormone production. The study concluded these effects were caused by tissue heating rather than non-thermal biological mechanisms. This demonstrates that microwave radiation can disrupt normal thyroid function through thermal effects.
