The radiation RF-EMF causes DNA damage, tissue heating, and disrupt the blood-brain barrier. These are real-world effects, and ARPANSA is actively involved with the EHS community, medical specialists and researchers. ARPANSA will continue review research on the health effects caused by EMF radiation.
RF-EMF can cause DNA damage
Exposed to man-made electromagnetic fields (EMFs) can cause DNA damage and other adverse health consequences. emf radiation can disrupt the intracellular ionic levels that are vital to maintain a cell's electrochemical balance. In turn, this can disrupt cell homeostasis, resulting damages to the DNA. Moreover exposure to EMFs can also trigger the production of free radicals as well as reactive oxygen species (ROS).
Exposure to RF-EMF radiation has been linked with alterations in the male germ cell's development. This results in the development of germ cells into spermatozoa as well functioning maturation as spermatozoa travel throughout the epididymis. To study the effects of RF-EMF on the development of male germ cells, a specifically-designed waveguide device was developed for the exposure of unrestrained mice to RF-EME with a dose of 2.2 W/kg.
In a recent study researchers have discovered that exposure to RF-EME caused an oxidative DNA injury in spermatozoa. Sperm DNA fragmentation increased by 18% following one 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).
However, RF-EMF radiation is not yet classified as a cancer-causing agent. However, numerous studies have found that exposure to RF-EMF can affect DNA integrity in a range of cell lines. In one study scientists exposed Vero cell lines to EMF at 100 Hz over about 45 minutes. They measured DNA damage 48 hours after exposure to determine whether the exposure affected DNA integrity.
The RF-EMF effect causes the heating of tissues
Although the effects of RF-EMF are usually considered as thermal in nature, some studies have revealed that non-thermal effects may also be evident. These may be the reason for some of the unresolved issues in the epidemiological study of EMF hypersensitivity. Therefore, it is important to look at the non-thermal aspects when conducting an exhaustive review.
The non-thermal effects that RF-EMF can have may be mediated by the cell membrane. what is emf radiation is an area which has already been thoroughly investigated. Particularly, the electrochemical behavior of cell membranes has been studied. emf radiation symptoms is that RF-EMF energy greater than 1 MHz is transferred to the tissue through dielectric as well as ionic dissipation. The theoretical studies have indicated that the energy transferred to the tissue could be as high as 200 kV/m.
The electrical properties of tissues are controlled by the composition and distribution of water molecules, ions, and other molecules in the body. This determines how absorbent EMR from RF is absorbed by different tissues. Organs with greater conductivity are likely to absorb more field and cause more of an effect. This is why the degree of heating in tissues does not increase steadily as it moves from the exterior to the body however, it is more prevalent in hot areas. Bone and fatty tissue are less susceptible to RF heating as compared to other tissues, since they have a low water content.
The depth of penetration of electromagnetic fields depends on the frequency and strength of field. Muscle tissue absorbs more field radiation than most tissues, and converts it into heat more effectively. Typically, the depth of penetration for RF EMF is determined by millimeters (mm). But, the greater the frequency, the deeper 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. Furthermore the impacts of EMF affect brain function are linked to neurodegenerative diseases. For instance, EMF from mobile phones can alter electroencephalogram activity as well as sleep patterns, and the activity of nitric oxide and xanthin oxide.
Researchers from the Vienna University have studied the effects of exposure to RF-EMF in brain cells. They also examined how ELF EMF on nervous system. Though the cellular mechanisms involved are not completely comprehended 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 known methods for regenerating myelin in the brain.
Researchers have discovered that exposure to frequencies of 900 MHz EMF caused a rise in the permeability of the BBB and also increased the indicators of neuronal injury in rodents. They also observed an increase in the extravasation of albumin to neurons. Additionally, they observed in 30 minutes 900 MHz exposure, 99mTc-MIBI increased its penetration in the cortex. However, this effect did not happen with Evans blue-based injections.
Despite these findings, RF-EMF does not have a clear method for disrupting the BBB. The evidence suggests that nonthermal EMF exposure can increase erythrocyte membrane permeability, which may alter the BBB and enhance the efflux of calcium ions. Furthermore, the presence a 99mTc-MIBI radiotracer within the brain is also linked to increasing the permeability and permeability of the BBB.
