The radiation from RF-EMF can cause DNA damage, tissue heating and alter the blood-brain barrier. These effects are real, and ARPANSA is active in collaborating in discussions with EHS community, medical professionals, and researchers. ARPANSA will continue to review research on 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 consequences. EMFs can affect intracellular ionic concentrations, which are essential to ensure a cell's electrochemical balance. It can also alter the balance of cell metabolism, resulting damages to the DNA. Additionally exposure to EMFs can cause an increase in the production of free radicals and reactive oxygen species (ROS).
Exposure to RF-EMF radiation has been linked to changes in the development of male germ cells. This results in the differentiation of the germ cell into spermatozoa, as well as functional maturation as the spermatozoa move throughout the epididymis. To study the effects of RF-EMF on male germ cells, a specially-built waveguide device was developed for the exposure of mice that were not restrained to RF-EME with a dose of 2.2 W/kg.
In a recent study researchers discovered that exposure to RF-EME caused the oxidative DNA damage of the spermatozoa. Sperm DNA fragmentation 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 radiation emitted by RF-EMF isn't yet classified as a cancer-causing agent. But, several studies have revealed that exposure to RF-EMF radiation can damage the integrity of DNA in variety of cell lines. In one study scientists exposed Vero cells to an EMF at 100 Hz over about 45 minutes. emf radiation assessed DNA damage for within 48 hours of exposure to determine if exposure affected the integrity of DNA.
RF-EMF causes tissue heating
While the effects of RF EMF are typically considered as thermal in nature, a few studies have shown that non-thermal effects may also be evident. These effects may account for some of the unresolved issues in epidemiological studies of EMF hypersensitivity. Therefore, it is important to look at the non-thermal aspects when conducting an exhaustive review.
The non-thermal effects of RF-EMF may occur at the cell membrane. This is an area where research has been thoroughly investigated. Particularly, the electrochemical behavior of cell membranes has been studied. It is believed that RF-EMF energy greater than 1 MHz is transmitted to the tissue via dielectric and ionic dissipation. The theoretical studies have indicated that the energy that is transferred to tissues could be up to 200 kV/m.
The electrical properties of tissues are controlled through the distribution and composition of water molecules and other molecules in the body. is emf radiation harmful determines how well absorbed 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 degree of tissue heating is not constant between the outside and inside and is only noticeable in hot spots. Bone and fatty tissues are less susceptible to RF heating than other tissues, because they are not as water-based. content.
The extent of the field's penetration depends on the strength and frequency that the electromagnetic field has. Muscle tissue absorbs more field radiation than most tissues, and converts it into heat more efficiently. Typically the penetration depth that RFEMF has is measured by millimeters (mm). However, what is emf radiation , 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. Additionally, the effects that EMF on brain activity have been linked to neurodegenerative disorders. For instance, EMF from mobile phones can affect electroencephalogram activity and sleep patterns, as well as the activities of nitric oxide and xanthin oxide.
Researchers at the Vienna University have studied the effects of RF-EMF exposure on brain cells. They also studied what effects ELF EMF on brain system. Although the cellular mechanisms involved are not completely known, there is a clear connection between exposure to ELF-EMF and myelin depletion. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. However, there are proven methods for regenerating myelin inside the brain.
Researchers have observed that exposure to frequencies of 900 millimeters EMF increased the permeability of the BBB and increased symptoms of neuronal damage in rodents. They also observed an increase in the extravasation of albumin to neurons. Additionally, they observed the following: after 30 mins of exposure at 900 MHz 99mTc-MIBI accelerated its permeation 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 method for disrupting the BBB. Research suggests that EMF exposure may increase erythrocyte cell membrane permeability, which may affect the BBB and increase calcium ion efflux. Additionally, the presence of a 99mTc-MIBI radiotracer within the brain has also been connected to an increase in the permeability and permeability of the BBB.
