Wellness Effects of EMF Radiation
The radiation from RF-EMF can cause DNA damage, tissue heating and even disrupt the blood-brain barrier. These are real-world effects, and ARPANSA is actively engaged with the EHS community, medical professionals and researchers. ARPANSA will continue to study research related to the health effects caused by EMF radiation.
RF-EMF damages DNA
Exposure to man-made electromagnetic fields (EMFs) can cause DNA damage, as well as other health consequences. EMFs can affect intracellular ionic concentrations, which are vital to maintain the balance of electrochemical activity in cells. This can disrupt cell homeostasis, resulting damages to the DNA. Moreover exposure to EMFs can also trigger an overproduction of free radicals as well as 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 as functional maturation as the spermatozoa travel through the epididymis. To determine the sensitivity of RF-EMF exposure to the development of male germ cells, a specifically-designed waveguide machine was designed for the purpose of exposing mice without restriction to RF-EMF in the range of 2.2 W/kg.
In a study that was conducted recently, researchers found that exposure to RF-EME causes the oxidative DNA damage of the spermatozoa. is emf radiation harmful increased by 18% after 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).
However, the RF-EMF radiation has not yet been recognized as a true carcinogen. However, several studies have shown that exposure to RF-EMF radiation can damage the integrity of DNA in range of cell varieties. In one study researchers subjected Vero cells with an EMF that was 100Hz, for 45 minutes. They assessed DNA damage for 48 hours after exposure to determine whether the exposure affected DNA integrity.
what is emf radiation of RF-EMF on tissue heating
While the effects of RF-EMF are generally believed to have thermal origins, a few studies have revealed that non-thermal influences are also present. These may be the reason for some of the unresolved issues in epidemiological studies on EMF hypersensitivity. It is therefore important to consider the non-thermal effects when conducting an extensive review.
The non-thermal effects that RF-EMF can have may be felt at the cell's membrane. This is a field where research has been extensively studied. In particular the electrochemical properties of cell membranes is being studied. Current understanding suggests that energy from RF-EMF greater than 1 MHz is transmitted to the tissue via 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 regulated in the form and quantity of water molecules and 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 of the field, and thus cause more of an impact. This is why the level of tissue heating is not constant from outside to inside 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 are low in water content.
The extent of the field's penetration is determined by the strength and frequency of field. Muscle tissue absorbs more energy than other tissues and converts it to heat more efficiently. Typically, the depth of penetration of RF-EMF is measured by millimeters (mm). However, the higher the frequency, deeper the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have discovered that RF-EMF could disrupt the blood-brain barrier, altering sleep patterns and neurotransmitter levels. In addition the impacts that EMF on brain activity have been linked to neurodegenerative disorders. For instance, EMF from mobile phones can alter electroencephalogram activity as well as sleep patterns, and the actions of nitric Oxide and xanthin oxidase.
Researchers at the Vienna University have studied the effects of RF-EMF exposure to brain cells. They also examined how ELF EMFs on the nervous system. While the mechanisms of the cell that are involved aren't fully comprehended however, there is an obvious connection between exposure to ELF-EMF and depletion of myelin. is emf radiation harmful might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. Fortunately, there are some proven methods for regenerating myelin within the brain.
Researchers have found that exposure to 900 Mhz EMF increased the permeability of BBB and also increased the indicators of neuronal injury in rodents. They also observed increased exovasation of albumin to neurons. Further, they found that after 30 minutes of exposure to 900 MHz 99mTc-MIBI accelerated its penetration in the cortex. However, this effect did not happen with Evans blue injections.
Despite these findings, RF-EMF does not have a clear method for disrupting the BBB. The evidence suggests that nonthermal EMF exposure may increase erythrocyte cell membrane permeability, which may alter the BBB and increase calcium ion efflux. Additionally, the presence of a 99mTc-MIBI radiotracer within the brain is also linked to increasing the permeability of the BBB.
