The radiation RF-EMF causes damage to DNA, heat up of tissues, and disrupt the blood brain barrier. These effects are real, and ARPANSA is active in collaborating in discussions with EHS group, the medical professionals and researchers. ARPANSA will continue review research on the health effects caused by EMF radiation.
RF-EMF causes DNA damage
The exposure to electromagnetic fields created by humans (EMFs) are associated with DNA damage, as well as other negative health consequences. EMFs can affect the intracellular ionic levels that are essential to ensure a cell's electrochemical balance. This can alter the balance of cell metabolism, resulting to DNA destruction. Additionally, exposure to EMFs is also associated with an overproduction of free radicals as well as reactive oxygen species (ROS).
Exposure to RF-EMF radiation has been linked to changes in the development of male germ cells. emf radiation results in the development of germ cells into spermatozoa, aswell functioning maturation as spermatozoa travel through the epididymis. To investigate the sensitivity of RF-EMF exposure to male germ cells, a specially-built waveguide machine was designed to expose mice that were not restrained to RF-EME with a dose of 2.2 W/kg.
In Get more info that was conducted recently, researchers have discovered that exposure to RF-EME causes the oxidative DNA damage of the spermatozoa. emf radiation increased by 18% following one week of treatment and by 23 percent after five weeks. Furthermore, DNA damage in mitochondria was observed by measuring the level of a biomarker, 8-hydroxy-2-deoxyguanosine (8-OH-dG).
Despite this, RF-EMF radiation is not yet recognized as a true carcinogen. But, several studies have found that exposure to RF-EMF can affect the integrity of DNA in variety of cell lines. In one such study scientists exposed Vero cells with an EMF that was 100Hz, for 45 minutes. They measured DNA damage 48 hours after exposure to determine if exposure affected the integrity of DNA.
The RF-EMF effect causes the heating of tissues
While the effects of RF EMF are generally considered to be thermal, a few studies have revealed that non-thermal effects may also be evident. These factors could be responsible for some of the unresolved observations in epidemiological studies of EMF hypersensitivity. Therefore, it is important to take into account non-thermal effects when conducting an extensive review.
The non-thermal effects of RF-EMF could be mediated by the cell membrane. This is an area where research has been thoroughly investigated. In particular, the electrochemical behavior of cell membranes has been investigated. It is believed that RF-EMF energy that exceeds 1 MHz is transferred to tissue via dielectric and Ionic dissipation. The theoretical studies have indicated that the energy that is transferred to the tissue could be as high as 200 kV/m.
The electric properties of tissue are controlled through the distribution and composition of water molecules and other molecules in the body. This determines how well absorbed EMR from RF is absorbed by different tissues. The tissues with the highest conductivity tend to absorb more field and cause more of an effect. This is why the level of tissue heating doesn't increase continuously between the outside and inside, but occurs in hot spots. Bone and fatty tissue is less susceptible to heating by RF as compared to other tissues, since they have a low water content.
The extent of penetration of the electromagnetic field depends on the strength and frequency of the field. Muscle tissue absorbs more field energy than other tissues and transforms it into heat more effectively. Usually, the depth of penetration for RF EMF is determined by millimeters (mm). However, the higher the frequency, shallower the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have found that RF-EMF could disrupt the blood-brain barrier which can alter sleep patterns and neurotransmitter levels. In addition to this, the effects on the effects of EMF in brain activities have been associated with neurodegenerative disorders. For example, EMF from mobile phones can affect electroencephalogram activity and sleep patterns, in addition to the actions of nitric Oxide and xanthin oxidase.
Researchers at Vienna University have studied the effects of exposure to RF EMF in brain cells. They also looked at what effects ELF EMF on brain system. While the mechanisms of the cell that play a role are not fully understood but there is a clear association between ELF-EMF exposure and myelin depletion. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. Fortunately, there are some tested methods to regenerate myelin in the brain.
Researchers have found that exposure to the frequency of 900 Mhz EMF caused a rise in the permeability of BBB and increased symptoms of neuronal damage in rodents. They also observed increased extravasation of albumin to neurons. Additionally, they observed in 30 minutes exposure to 900 MHz, 99mTc-MIBI increased its diffusion in the cortex. But this effect didn't occur when using Evans blue injections.
Despite these findings, RF-EMF is not able to provide a definitive mechanism for disrupting the BBB. Research suggests that EMF exposure can increase erythrocyte membrane permeability, which may affect the BBB and also increase the efflux of calcium ions. Furthermore, the presence a 99mTc-MIBI radiotracer within the brain is also associated with increased permeability of the BBB.
