The radiation from RF-EMF can cause DNA damage, tissue heating and disrupt the blood-brain barrier. These effects are real and ARPANSA is actively engaged with 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 damages DNA
exposed to electromagnetic fields that are created by man (EMFs) can cause DNA damage, as well as other negative health consequences. EMFs can alter the intracellular ionic levels, which are crucial to maintain the balance of electrochemical activity in cells. In turn, this can cause disruption to cell homeostasis and result to DNA damage. Additionally, exposure to EMFs is also linked to the production of free radicals and reactive oxygen species (ROS).
Exposure to RF-EMF radiation has been linked to changes in male germ cells' development. This is due to the differentiation of the germ cell into spermatozoa, aswell functioning maturation when the spermatozoa travel across the epididymis. To determine the effect of RF-EMF exposure on the development of male germ cells, a specifically-designed waveguide machine was designed for the exposure of unrestrained mice to RF-EME with a dose of 2.2 W/kg.
In a recent study researchers found that exposure to RF-EME triggered the oxidation of DNA in the spermatozoa. Sperm DNA fragmentation increased by 18% following one week of treatment and by 23 percent 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 recognized as a true carcinogen. However, numerous studies have shown that RF-EMF exposure can impair the integrity of DNA in variety of cell lines. In one such study, scientists subjected Vero cell lines to EMF that was 100Hz, for 45 minutes. is emf radiation harmful measured DNA damage within 48 hours of exposure to determine whether the exposure had a negative effect on DNA integrity.
The effect of RF-EMF on tissue heating
While the effects of RF-EMF are generally considered as thermal in nature, a few studies have shown that non-thermal effects are also evident. These factors could be responsible for certain of the unsolved findings in the epidemiological study of EMF hypersensitivity. It is therefore important to take into account non-thermal effects when conducting a systematic review.
Effects that are not thermal from RF-EMF may occur at the cell membrane. This is an area where research has been extensively examined. Particularly, the electrochemical behavior of cell membranes has been investigated. Current understanding suggests that energy from RF-EMF higher than 1 MHz is transferred to the tissue via dielectric dissipation and ionic discharge. Previous theoretical analyses indicated that the energy that is transferred to tissues could be as high as 200 kV/m.
The electric properties of tissues are controlled by the composition and distribution of water molecules, ions and other molecules in the body. This determines how well absorbed EMR RF is by various tissues. The tissues with the highest conductivity tend to absorb more EMR field and produce more of an impact. what is emf radiation is why the level of heating in tissues doesn't increase continuously from outside to inside and is only noticeable in hot spots. Bone and fatty tissue is less prone to RF heating than other tissues because they have a low water content.
The extent of the field's electromagnetic energy depends on the strength and frequency of the field. Muscle tissue is more able to absorb field energies than the other tissue, and converts it to heat more effectively. Usually the penetration depth of RF-EMF is measured in millimeters (mm). But, the higher the frequency, the shallower the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have found that RF-EMF can alter the blood-brain-barrier changing sleep patterns as well as neurotransmitter levels. Additionally the impacts that EMF on brain activity are linked to neurodegenerative disorders. For example, EMF from mobile phones can alter electroencephalogram activity as well as sleep patterns, and the actions of nitric Oxide and xanthin oxidase.
Researchers from the Vienna University have studied the effects of exposure to RF-EMF in brain cells. They also studied what effects ELF EMF on the nervous system. While the mechanisms of the cell that are involved aren't fully comprehended but 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 tested methods to regenerate myelin inside the brain.
Researchers have discovered that exposure to 900 MHz EMF caused a rise in the permeability of the BBB and increased the signs of neuronal injury in rodents. They also observed an increase in the release of albumin into neurons. Furthermore, they discovered that after 30 minutes of exposure to 900 MHz, 99mTc-MIBI increased its permeation to the cerebral cortex. However this effect didn't occur when using Evans blue injections.
Despite these findings, RF EMF has no clear mechanism for disrupting the BBB. Evidence suggests that non-thermal EMF exposure can increase erythrocyte membrane permeability. This could affect the BBB and enhance calcium ion efflux. Additionally, the presence of a 99mTcMIBI radiotracer inside the brain has also been linked to increased permeability of BBB.
