The radiation from RF-EMF can cause damage to DNA, increase the temperature of tissues and even disrupt the blood-brain barrier. These effects are real, and ARPANSA is actively engaged within the EHS group, the medical experts as well as researchers. The agency will continue to examine research regarding the health effects of EMF radiation.
RF-EMF can cause DNA damage
Exposed to man-made electromagnetic fields (EMFs) can cause DNA damage and other health consequences. EMFs can disrupt intracellular ionic concentrations, which are crucial to maintain the balance of electrochemical activity in cells. It can also disrupt cell homeostasis, resulting damages to the DNA. Moreover, exposure to EMFs can cause the production of free radicals as well as reactive oxygen species (ROS).
The exposure to radiation from RF-EMF has been linked with alterations in male germ cell development. This is due to the differentiation of the germ cell into spermatozoa, as well functional maturation when the spermatozoa travel through the epididymis. To determine the sensitivity of RF-EMF exposure to male germ cells A specially designed waveguide machine was designed for the exposure of mice without restriction to RF-EMF with a dose of 2.2 W/kg.
In a recent study researchers found that exposure to RF EME caused oxidative DNA damage in spermatozoa. Sperm DNA fragmentation increased by 18% following an entire week of treatment and by 23% after 5 weeks. Furthermore, DNA damage in mitochondria was observed by measuring the level of a biomarker, 8-hydroxy-2-deoxyguanosine (8-OH-dG).
Although RF-EMF radiation is not yet considered to be a carcinogen. However, numerous studies have shown that RF-EMF exposure can impair DNA health in variety of cell lines. In one of these studies, scientists were exposed Vero cells to an EMF at 100 Hz over 45 minutes. They measured DNA damage 48 hours after exposure to determine if exposure affected DNA integrity.
RF-EMF causes tissue heating
While the effects of RF EMF are usually believed as thermal in nature, some studies have revealed that non-thermal effects are also observed. These may be the reason for some of the unresolved observations in the epidemiological study of EMF hypersensitivity. It is therefore important to take into account non-thermal effects when conducting a systematic review.
The non-thermal effects of RF-EMF could occur at the cell membrane. This is a field of research that has been thoroughly investigated. In particular the electrochemical properties of cell membranes is being studied. The current understanding is that energy from RF-EMF higher than 1 MHz is transmitted to the tissue via dielectric and ionic dissipation. Previous theoretical analyses indicated that the energy transfer to the tissue could be as high as 200 kV/m.
The electrical properties of tissues are regulated by the composition and distribution of water molecules, ions, and other substances in the body. This determines how absorbed EMR RF is by various tissues. Organs with greater conductivity are likely to absorb more of the EMR field and produce more of an impact. This is why the level of heating in tissues doesn’t increase continuously as it moves from the exterior to however, it is more prevalent in hot spots. Bone and fatty tissue is less susceptible to RF heating as compared to other tissues, since they are low in water content.
The extent of the field’s penetration is determined by the frequency and strength of the field. Muscle tissue absorbs more energy than other tissues, and converts it to heat more efficiently. Usually the depth of penetration for RF EMF is determined by millimeters (mm). However, the higher the frequency, the deeper the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have discovered that RF-EMF can alter the blood-brain-barrier change sleep patterns as well as neurotransmitter levels. Additionally to this, the effects of EMF in brain activities have been linked to neurodegenerative disorders. For instance, EMF from mobile phones could affect the electroencephalogram’s activity and sleep patterns, in addition to the actions of nitric Oxide and xanthin oxide.
Researchers at Vienna University have studied the effects of exposure to RF EMF to brain cells. They also studied the effects of ELF EMF on the nervous system. Although the cellular mechanisms involved are not completely understood but there is a clear relationship between exposure to ELF EMF and myelin depletion. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. However, there are tested methods to regenerate myelin in the brain.
Researchers have discovered that exposure to the frequency of 900 MHz EMF caused a rise in the permeability of the BBB and also increased the symptoms of neuronal damage in rodents. emf radiation observed increased extravasation of albumin to neurons. Additionally, they observed that after 30 minutes of 900 MHz exposure, 99mTc-MIBI increased its diffusion to the cerebral cortex. But this effect didn’t happen with Evans blue injections.
However, RF-EMF has no clear mechanism to disrupt the BBB. Research suggests that EMF exposure increases erythrocyte membrane permeability, which could affect the BBB and enhance the efflux of calcium-ion. Additionally, the presence of a 99mTcMIBI radiotracer inside the brain has been connected to increased permeability of BBB.
