Health and fitness Effects of EMF Radiation
RF-EMF radiation can cause damages to DNA and tissue, and can disrupt the blood-brain-barrier. These effects are real and ARPANSA is actively engaged within the EHS communities, medical professionals as well as researchers. is emf radiation harmful will continue to review research on the health impacts of EMF radiation.
RF-EMF causes DNA damage
Exposure to man-made electromagnetic fields (EMFs) can cause DNA damage and other negative health consequences. EMFs can affect the intracellular ionic levels, which are crucial to maintain the balance of electrochemical activity in cells. emf radiation can disrupt cell homeostasis, resulting to DNA damage. Additionally exposure to EMFs is also linked to an overproduction of free radicals and reactive oxygen species (ROS).
The exposure to radiation from RF-EMF has been linked with alterations in male germ cells' development. This results in the transformation of germ cells into spermatozoa, as well maturation of the functional aspect as spermatozoa pass throughout 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 exposure of unrestrained mice to RF-EMF at 2.2 W/kg.
In a study that was conducted recently, researchers found exposure to RF-EME causes the oxidation of DNA in the spermatozoa. Sperm DNA fragmentation increased by 18% following a 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, RF-EMF radiation is not yet considered to be a carcinogen. But, numerous studies have found that RF-EMF exposure can impair DNA integrity in a variety of cell types. In one such study researchers exposed Vero cell lines to EMF that was 100Hz, for 45 minutes. They assessed DNA damage for 48 hours after exposure to determine if exposure affected DNA integrity.
The effect of RF-EMF on tissue heating
While the effects of RF-EMF are usually believed to be thermal, a few studies have demonstrated that non-thermal effects may also be observed. These factors could be responsible for some of the unsolved issues in epidemiological studies of EMF hypersensitivity. Therefore, it is important to look at the non-thermal aspects when conducting an exhaustive review.
Non-thermal effects from RF-EMF could occur at the cell membrane. is emf radiation harmful is an area of research that has been extensively examined. Particularly, the electrochemical behavior of cell membranes is being studied. Current understanding suggests that energy from RF-EMF higher than 1 MHz is transferred to tissues via dielectric and ionic dissipation. The theoretical studies have indicated that the energy transfer to the tissue could be as high as 200 kV/m.
The electric properties of tissues are regulated by the composition and distribution of water molecules, ions and other molecules in the body. This determines how well absorbed RF EMR is by different tissues. Organs with greater conductivity are likely to absorb more field, and thus cause more of an impact. This is the reason why the amount of heating in tissues doesn't increase continuously as it moves from the exterior to, but occurs in hot areas. Bone and fatty tissue are less susceptible to heating by RF as compared to other tissues, since they are not as water-based. content.
The depth of penetration of the electromagnetic field is determined by the frequency and strength of field. Muscle tissue absorbs more radiation than most tissues, and transforms it into heat more effectively. 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 which can alter sleep patterns and neurotransmitter levels. Additionally to this, the effects on the effects of EMF affect brain function are linked to neurodegenerative diseases. For example, EMF from mobile phones could affect the electroencephalogram's activity and sleep patterns, and the actions of nitric Oxide and xanthin oxidase.
Researchers at Vienna University have studied the effects of exposure to RF-EMF on brain cells. They also studied how ELF EMF on nervous system. While the mechanisms of the cell involved are not completely understood, there is a clear association between ELF-EMF exposure and myelin depletion. 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 discovered that exposure to frequencies of 900 Mhz EMF caused a rise in the permeability of the BBB and raised symptoms of neuronal damage in rats. They also observed an increase in the extravasation of albumin to neurons. Additionally, they observed in 30 minutes exposure at 900 MHz 99mTc-MIBI accelerated its penetration in the cortex. However this effect didn't happen with Evans blue injections.
Despite these findings, RF EMF does not have a clear mechanism to disrupt the BBB. Evidence suggests that non-thermal EMF exposure may increase erythrocyte cell membrane permeability. This could affect the BBB and also increase the efflux of calcium-ion. Furthermore, the presence a 99mTcMIBI radiotracer inside the brain is also connected to increasing the permeability of BBB.
