emf radiation -EMF radiation can cause DNA damage, tissue heating and alter the blood brain barrier. These effects are real and ARPANSA is actively engaged within the EHS communities, medical experts and researchers. The agency will continue to review research on the health impacts of EMF radiation.
RF-EMF damages DNA
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 a cell's electrochemical balance. This can disrupt cell homeostasis, resulting damages to the DNA. Additionally exposure to EMFs can also trigger an increase in the production of free radicals and reactive oxygen species (ROS).
The exposure to radiation from RF-EMF has been associated with changes in male germ cell development. This results in the development of germ cells into spermatozoa, aswell functioning maturation as spermatozoa pass across the epididymis. To study the effects of RF-EMF on the development of male germ cells, a specially-built waveguide machine was constructed for the purpose of exposing mice without restriction to RF-EMF at 2.2 W/kg.
In a recent study researchers have discovered that exposure to RF EME caused an oxidative DNA injury in 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).
Although the RF-EMF radiation has not yet been recognized as a true carcinogen. But, several studies have found that exposure to RF-EMF radiation can damage DNA health in range of cell varieties. In one such study, scientists were exposed Vero cells with an EMF at 100 Hz over about 45 minutes. They measured DNA damage within 48 hours of exposure to determine if the exposure affected DNA integrity.
RF-EMF causes tissue heating
Although the effects of RF-EMF are usually thought to have thermal origins, some studies have demonstrated that non-thermal effects may also be observed. These factors could be responsible for some of the unresolved observations in the epidemiological study of EMF hypersensitivity. It is therefore important to take into account non-thermal effects when conducting a systematic review.
The non-thermal effects of RF-EMF may occur at the cell membrane. This is a field of research that has been extensively studied. Particularly, the electrochemical behavior of cell membranes has been studied. Current understanding suggests that RF-EMF energy higher than 1 MHz is transferred to tissue through dielectric and Ionic dissipation. Studies of the theory have suggested that the energy that is transferred to the tissue could be as high as 200 kV/m.
The electric properties of tissues are controlled through the distribution and composition of water molecules, and other substances in the body. what is emf radiation determines how well absorbed EMR from RF is absorbed by different tissues. The tissues with the highest conductivity tend to absorb more of the EMR field and produce more of an impact. This is the reason why the amount of tissue heating doesn't increase continuously as it moves from the exterior to the body however, it is more prevalent in hot areas. Bone and fatty tissue is less susceptible to heating by RF than other tissues, because they are low in water content.
The intensity of the field's penetration is determined by the frequency and strength of field. Muscle tissue absorbs more energy than other tissues, and converts it into heat more efficiently. Usually the depth of penetration of RF-EMF is measured in millimeters (mm). However, the higher the frequency, deeper the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have discovered that RF EMF can disrupt the blood-brain barrier, altering sleep patterns and neurotransmitter levels. In addition, the effects that EMF in brain activities have been associated with neurodegenerative diseases. For https://fnote.me/notes/KWfp0h , EMF from mobile phones can alter electroencephalogram activity as well as sleep patterns, in addition to the activity of nitric oxide and xanthin oxidase.
Researchers from the Vienna University have studied the effects of RF-EMF exposure in brain cells. They also studied the effects of ELF EMF on brain system. While the mechanisms of the cell that play a role are not fully comprehended however, there is an obvious connection between exposure to ELF-EMF and myelin depletion. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. However, there are known methods for regenerating myelin inside the brain.
Researchers have observed that exposure to frequencies of 900 MHz EMF increased the permeability of the BBB and increased signs of neuronal damage in rats. They also observed increased extravasation of albumin to neurons. Furthermore, they discovered the following: after 30 mins of exposure at 900 MHz, 99mTc-MIBI increased its diffusion into the brain. However this effect did not happen with Evans blue-based injections.
Despite these findings, RF EMF has no clear method for disrupting the BBB. Evidence suggests that non-thermal EMF exposure may increase erythrocyte cell membrane permeability, which may alter the BBB and increase calcium ion efflux. Moreover, the presence of a 99mTc-MIBI radiotracer within the brain is also connected to increasing the permeability of BBB.
