The radiation RF-EMF causes DNA damage, tissue heating, and disrupt the blood-brain barrier. These effects are real, and ARPANSA is active in collaborating in discussions with EHS community, medical specialists and researchers. The agency will continue study research related to the health impacts of EMF radiation.
DNA damage is caused by RF-EMF
The exposure to electromagnetic fields created by humans (EMFs) can cause DNA damage, as well as other adverse health adverse effects. EMFs can affect the intracellular ionic concentrations that are vital to maintain a cell's electrochemical balance. It can also disrupt cell homeostasis, resulting damages to the DNA. Additionally exposure to EMFs is also associated with the production 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 involves the development of germ cells into spermatozoa, aswell functioning maturation when the spermatozoa travel throughout the epididymis. To investigate the effects of RF-EMF on male germ cells A specially designed waveguide machine was constructed to expose non-restrained mice to RF EME with a dose of 2.2 W/kg.
In a recent study, researchers found exposure to RF-EME causes the oxidation of DNA in the spermatozoa. Sperm DNA fragmentation increased by 18% following one week of treatment and by 23 percent 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 considered a carcinogen. However, numerous studies have found that RF-EMF exposure can impair DNA health in variety of cell varieties. In one such study researchers subjected Vero cells with an EMF at 100 Hz over 45 minutes. They assessed DNA damage for within 48 hours of exposure to determine if exposure had a negative effect on DNA integrity.
RF-EMF causes tissue heating
Although the effects of RF-EMF are usually considered to have thermal origins, some studies have revealed that non-thermal effects may also be present. These factors could be responsible for some of the unresolved observations in the epidemiological study of EMF hypersensitivity. Therefore, it is important to consider the non-thermal effects when conducting a systematic review.
is emf radiation harmful that are not thermal from RF-EMF may occur at the cell membrane. This is a field of research that has been extensively investigated. In particular the electrochemical properties of cell membranes has been investigated. It is believed that energy from RF-EMF higher than 1 MHz gets transferred to tissues via dielectric dissipation and ionic discharge. Previous theoretical analyses indicated that the energy transferred to tissues could be as high as 200 kV/m.
The electrical properties of tissues are regulated through the distribution and composition of water molecules and other molecules within the body. This determines how absorbent EMR RF is by various tissues. Organs with greater conductivity are likely to absorb more of the EMR field and produce more of an effect. This is the reason the degree of heat generated by tissue does not increase steadily as it moves from the exterior to the body however, it is more prevalent in hot spots. Bone and fatty tissue is less susceptible to RF heating as compared to other tissues, since they have a low water content.
The depth of the field's penetration is determined by the strength and frequency of the field. Muscle tissue absorbs more field radiation than most tissues, and converts it into heat more efficiently. Typically, the depth of penetration that RFEMF has is measured in millimeters (mm). The greater the frequency, the shallower the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have discovered that RF-EMF can disrupt the blood-brain barrier changing sleep patterns as well as neurotransmitter levels. Furthermore to this, the effects that EMF on brain activity are linked to neurodegenerative disorders. For example, EMF from mobile phones could affect the electroencephalogram's activity and sleep patterns, as well as the actions of nitric Oxide and xanthin oxidase.
Researchers at Vienna University have studied the effects of RF-EMF exposure on brain cells. They also looked at how ELF EMFs on the nervous system. Although emf radiation aren't completely understood but there is a clear relationship between exposure to ELF EMF and depletion of myelin. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. However, there are proven methods for regenerating myelin within the brain.
Researchers have observed that exposure to the frequency of 900 millimeters EMF caused a rise in the permeability of BBB and raised signs of neuronal damage in rodents. https://felonyquiver7.bravejournal.net/post/2023/03/29/Wellness-Effects-of-EMF-Radiation2 observed increased extravasation of albumin to neurons. Additionally, they observed the following: after about 30 min of exposure to 900 MHz 99mTcMIBI increased its penetration in the cortex. However, this effect did not occur when using Evans blue injections.
Despite these findings, RF-EMF is not able to provide a definitive mechanism for disrupting the BBB. The evidence suggests that nonthermal EMF exposure increases erythrocyte membrane permeability, which could influence the BBB and enhance the efflux of calcium ions. Moreover, the presence of a 99mTc-MIBI radiotracer within the brain has been connected to increased permeability of BBB.
