The radiation RF-EMF causes damages to DNA and tissue and even disrupt the blood-brain barrier. These effects are real, and ARPANSA is active in collaborating within the EHS community, medical professionals, and researchers. ARPANSA will continue to study research related to the health impacts of EMF radiation.
RF-EMF damages DNA
The exposure to electromagnetic fields created by humans (EMFs) can cause DNA damage and other health consequences. EMFs can affect the intracellular ionic concentrations that are crucial to maintain the electrochemical balance of cells. It can also cause disruption to cell homeostasis and result in DNA damage. Moreover exposure to EMFs is also associated with an overproduction of free radicals and reactive oxygen species (ROS).
Exposure to RF-EMF radiation has been linked to changes in the male germ cell's development. This results in the transformation of germ cells into spermatozoa, as well maturation of the functional aspect as spermatozoa travel throughout the epididymis. To determine the sensitivity of RF-EMF exposure to the development of male germ cells A specially designed waveguide machine was designed to expose non-restrained mice to RF-EMF in the range of 2.2 W/kg.
In a recent study researchers have discovered that exposure to RF-EME triggered an oxidative DNA damage to the spermatozoa. Sperm DNA fragmentation increased by 18% following an entire week of treatment and by 23% 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 considered to be a carcinogen. But, numerous studies have shown that exposure to RF-EMF can affect DNA integrity in a range of cell types. In one of these studies, scientists were exposed Vero cells with an EMF at 100 Hz over about 45 minutes. They evaluated DNA damage at 48 hours following exposure to determine if the exposure affected the integrity of DNA.
RF-EMF causes tissue heating
While the effects of RF-EMF are typically believed to have thermal origins, a few studies have demonstrated that non-thermal effects are also present. These factors could be responsible for certain of the unsolved findings in epidemiological studies of EMF hypersensitivity. It is therefore important to take into account non-thermal effects when conducting systematic reviews.
The non-thermal effects of the RF-EMF can occur on the cell's membrane. This is a field which has already been extensively examined. Particularly the electrochemical properties of cell membranes is being studied. Current understanding suggests that energy generated by RF-EMF greater than 1 MHz is transferred to tissues via dielectric and ionic dissipation. Previous theoretical analyses indicated that the energy that is transferred to tissues could be as high as 200 kV/m.
The electrical properties of tissues are controlled in the form and quantity of water molecules and ions, and other molecules inside the body. This determines how absorbed EMR RF is by various tissues. The tissues with the highest conductivity tend to absorb more of the EMR field and produce more of an effect. This is the reason why the amount of tissue heating doesn't increase continuously as it moves from the exterior to however, it is more prevalent in hot areas. Bone and fatty tissue is less susceptible to RF heating than other tissues because they have a low water content.
The intensity of the field's electromagnetic energy depends on the strength and frequency of the field. Muscle tissue is more able to absorb field energy than other tissues, and converts it to heat more effectively. Typically, the depth of penetration of RF-EMF is measured as millimeters (mm). But, the higher the frequency, more shallow the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have discovered that RF-EMF could disrupt the blood-brain barrier which can alter sleep patterns and neurotransmitter levels. In addition the impacts of EMF affect brain function are linked to neurodegenerative disorders. For instance, EMF from mobile phones can affect electroencephalogram activity and sleep patterns, in addition to the actions of nitric Oxide and xanthin oxide.
what is emf radiation from the Vienna University have studied the effects of exposure to RF-EMF to brain cells. emf radiation examined how ELF EMF on the nervous system. Although the cellular mechanisms aren't completely comprehended however, there is an obvious 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 proven methods for regenerating myelin within the brain.
Researchers have found that exposure to the frequency of 900 MHz EMF caused a rise in the permeability of BBB and raised the signs of neuronal injury in rats. They also observed increased extravasation of albumin to neurons. Furthermore, they discovered the following: after about 30 min of exposure at 900 MHz 99mTc-MIBI accelerated its permeation to the cerebral cortex. But this effect didn't occur with Evans blue-based injections.
However, RF-EMF has no clear mechanism to disrupt the BBB. The evidence suggests that nonthermal EMF exposure can increase erythrocyte membrane permeability, which may affect the BBB and also increase the efflux of calcium-ion. Furthermore, emf radiation a 99mTc-MIBI radiotracer in the brain is also linked to increasing the permeability of the BBB.
