The radiation from RF-EMF can cause damages to DNA and tissue and even disrupt the blood-brain barrier. These are real-world effects, and ARPANSA is actively involved in discussions with EHS group, the medical specialists and researchers. The agency will continue study research related to the health effects of EMF radiation.
RF-EMF causes 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 intracellular ionic concentrations, which are essential to ensure the balance of electrochemical activity in cells. In turn, this can disrupt cell homeostasis, resulting in DNA damage. Moreover, exposure to EMFs is also linked to an overproduction of free radicals as well as reactive oxygen species (ROS).
Exposure to RF-EMF radiation has been linked to changes in male germ cell development. This results in the differentiation of the germ cell into spermatozoa, as well as functional maturation as the spermatozoa pass across the epididymis. To determine the effects of RF-EMF on the development of male germ cells A specially designed waveguide device was developed to expose non-restrained mice to RF-EMF in the range of 2.2 W/kg.
In https://hawkstage73.werite.net/post/2023/03/29/Health-Effects-of-EMF-Radiation that was conducted recently, researchers discovered that exposure to RF-EME caused an oxidative DNA damage to the spermatozoa. Sperm DNA fragmentation was increased by 18% after 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).
Despite this the fact that RF-EMF radiation isn't yet recognized as a true carcinogen. However, numerous studies have shown that exposure to RF-EMF can affect the integrity of DNA in variety of cell varieties. In one of these studies researchers were exposed Vero cells to an EMF at 100 Hz over about 45 minutes. They measured DNA damage 48 hours after exposure to determine if the exposure affected DNA integrity.
is emf radiation harmful -EMF effect causes the heating of tissues
Although the effects of RF-EMF are generally thought to be thermal, a few studies have revealed that non-thermal effects may also be evident. These effects may account for certain of the unsolved findings in epidemiological studies on EMF hypersensitivity. This is why it is crucial to look at the non-thermal aspects when conducting an exhaustive review.
The non-thermal effects of RF-EMF could occur at the cell membrane. This is an area which has already been extensively examined. Particularly the electrochemical properties of cell membranes has been studied. Current understanding suggests that energy generated by RF-EMF greater than 1 MHz is transferred into the tissues through dielectric and ionic dissipation. Previous theoretical analyses indicated that the energy transfer to tissues could be as high as 200 kV/m.
The electric properties of tissue are regulated through the distribution and composition of water molecules, and other molecules within the body. This determines how absorbent RF EMR is by different tissues. The tissues with the highest conductivity tend to absorb more field, and thus cause more of an effect. This is why the level of heating in tissues is not constant between the outside and inside and is only noticeable in hot areas. Bone and fatty tissues are less susceptible to heating by RF as compared to other tissues, since they have a low water content.
The intensity of penetration of the electromagnetic field is determined by the strength and frequency that the electromagnetic field has. Muscle tissue absorbs more field energies than the other tissue and converts it into heat more effectively. Typically the depth of penetration that RFEMF has is measured by millimeters (mm). But, the higher the frequency, deeper the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have found that RF-EMF can alter the blood-brain-barrier, altering sleep patterns and neurotransmitter levels. Additionally the impacts that EMF on brain activity have been linked to neurodegenerative disorders. For instance, EMF from mobile phones could affect the electroencephalogram's activity and sleep patterns, as well as the activities of nitric oxide and xanthin oxidase.
Researchers at Vienna University have studied the effects of RF-EMF exposure to brain cells. They also looked at the effects of ELF EMF on the brain system. Though the cellular mechanisms aren't completely understood, there is a clear connection between exposure to ELF-EMF 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 frequencies of 900 Mhz EMF enhanced the permeability of BBB and caused an increase in the signs of neuronal injury in rodents. They also observed an increase in the extravasation of albumin into neurons. Furthermore, they discovered in 30 minutes exposure to 900 MHz 99mTc-MIBI accelerated its diffusion into the brain. But, this effect did not happen with Evans blue injections.
However, RF-EMF has emf radiation symptoms for disrupting the BBB. Research suggests that EMF exposure can increase erythrocyte membrane permeability, which may influence the BBB and increase calcium ion efflux. Moreover, the presence of a 99mTc-MIBI radiotracer in the brain is also associated with increased permeability of the BBB.
