The radiation RF-EMF causes damage to DNA, heat up of tissues and even disrupt the blood brain barrier. These are real-world effects, and ARPANSA is actively involved within the EHS group, the medical professionals and researchers. ARPANSA will continue review research on the health effects caused by EMF radiation.
RF-EMF can cause DNA damage
The exposure to electromagnetic fields created by humans (EMFs) are associated with DNA damage as well as adverse health adverse effects. EMFs can alter the intracellular ionic levels that are crucial to maintain the balance of electrochemical activity in cells. It can also disrupt cell homeostasis, resulting in DNA damage. Additionally, exposure to EMFs is also associated with an overproduction of free radicals and reactive oxygen species (ROS).
The exposure to radiation from RF-EMF has been associated with changes in male germ cell development. This is due to the development of germ cells into spermatozoa, aswell functional maturation when the spermatozoa pass throughout the epididymis. To determine the sensitivity of RF-EMF exposure to the development of male germ cells, a specially-built waveguide device was developed for the purpose of exposing mice without restriction to RF-EMF with a dose of 2.2 W/kg.
In emf radiation , researchers found that exposure to RF-EME causes oxidative DNA damage in spermatozoa. Sperm DNA fragmentation was increased by 18% after a 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 the radiation emitted by RF-EMF isn't yet considered to be a carcinogen. But, several studies have shown that RF-EMF exposure can impair DNA health in range of cell varieties. In what is emf radiation subjected Vero cell lines to EMF of 100 Hz for 45 minutes. They assessed DNA damage for within 48 hours of exposure to determine if exposure affected DNA integrity.
what is emf radiation of RF-EMF on tissue heating
While the effects of RF EMF are generally believed to have thermal origins, a few studies have revealed that non-thermal influences are also observed. These may be the reason for certain of the unsolved findings in the epidemiological study of EMF hypersensitivity. This is why it is crucial to consider the non-thermal effects when conducting an extensive review.
The non-thermal effects that RF-EMF can have may be felt at the cell's membrane. This is a field where research has been extensively studied. In particular, the electrochemical behavior of cell membranes has been investigated. The current understanding is that energy from RF-EMF higher than 1 MHz is transmitted to the tissue through dielectric and ionic dissipation. Studies of the theory have suggested that the energy that is transferred to the tissue could be as high as 200 kV/m.
The electric properties of tissue are controlled by the composition and distribution of water molecules, ions and other substances in the body. This determines how absorbed EMR from RF is absorbed by different tissues. The tissues with the highest conductivity tend to absorb more EMR field and produce more of an effect. This is why the degree of heating in tissues is not constant from outside to inside and is only noticeable in hot spots. Bone and fatty tissues are less susceptible to RF heating than other tissues, because they are low in water content.
The extent of the field's penetration depends on the strength and frequency that the electromagnetic field has. Muscle tissue is more able to absorb field energy than other tissues, and converts it into heat more effectively. Typically the depth of penetration that RFEMF has is measured as millimeters (mm). But, the greater the frequency, the more shallow the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have discovered that RF EMF could disrupt the blood-brain barrier change sleep patterns as well as neurotransmitter levels. Furthermore, the effects on the effects of EMF in brain activities have been associated with neurodegenerative diseases. For instance, EMF from mobile phones can affect electroencephalogram activity and sleep patterns, as well as the activities of nitric oxide and xanthin oxidase.
Researchers at Vienna University have studied the effects of exposure to RF-EMF on brain cells. They also studied what effects ELF EMF on the brain system. Though the cellular mechanisms that play a role are not fully comprehended, there is a clear association between ELF-EMF exposure and depletion of myelin. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. Fortunately, there are some tested methods to regenerate myelin within the brain.
Researchers have observed that exposure to 900 Mhz EMF caused a rise in the permeability of the BBB and also increased the signs of neuronal damage in rodents. They also observed increased extravasation of albumin to neurons. Further, they found the following: after 30 mins of exposure to 900 MHz 99mTcMIBI increased its diffusion into the brain. However, this effect did not occur when using Evans blue injections.
However, RF-EMF is not able to provide a definitive mechanism for disrupting the BBB. Evidence suggests that non-thermal EMF exposure increases erythrocyte membrane permeability, which may alter the BBB and increase calcium ion efflux. Additionally, the presence of a 99mTc-MIBI radiotracer within the brain has been linked to increasing the permeability of BBB.
