Health Effects of EMF Radiation
The radiation RF-EMF causes DNA damage, tissue heating and alter the blood brain barrier. These effects are real and ARPANSA is actively involved within the EHS communities, medical experts, and researchers. ARPANSA will continue to examine research regarding the health effects caused by EMF radiation.
RF-EMF causes DNA damage
Exposure to man-made electromagnetic fields (EMFs) can cause DNA damage, as well as other adverse health consequences. EMFs can affect intracellular ionic concentrations, which are crucial to maintain the balance of electrochemical activity in cells. It can also disrupt cell homeostasis, resulting to DNA destruction. Moreover exposure to EMFs can cause an increase in the production of free radicals as well as reactive oxygen species (ROS).
Exposure to RF-EMF radiation has been linked with alterations in male germ cell development. This results in the transformation of germ cells into spermatozoa, as well functioning maturation as spermatozoa pass throughout the epididymis. To investigate the effect of RF-EMF exposure on male germ cell development, a specially-built 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 caused oxidative DNA damage 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).
However, RF-EMF radiation is not yet recognized as a true carcinogen. However, several studies have shown that exposure to RF-EMF can affect DNA health in variety of cell varieties. In one such study scientists exposed Vero cells to an EMF at 100 Hz over 45 minutes. They measured DNA damage 48 hours after exposure to determine if the exposure affected the integrity of DNA.
RF-EMF causes tissue heating
Although the effects of RF-EMF are usually considered as thermal in nature, some studies have revealed that non-thermal effects are also observed. These effects may account for some of the unresolved observations in epidemiological studies on EMF hypersensitivity. This is why it is crucial to consider the non-thermal effects when conducting a systematic review.
The non-thermal effects of RF-EMF could be mediated by the cell membrane. This is a field which has already been extensively studied. In particular the electrochemical properties of cell membranes is being studied. The current understanding is that energy from RF-EMF higher than 1 MHz is transferred to the tissue via dielectric and the dissipation of ions. Previous theoretical analyses indicated that the energy transferred to tissues could be up to 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 absorbed EMR RF is by various tissues. Tissues with higher conductivity tend to absorb more of the field and 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 spots. https://fnote.me/notes/6DWw3c and fatty tissues are less prone to RF heating as compared to other tissues, since they are low in water content.
The depth of penetration of electromagnetic fields depends on the strength and frequency that the electromagnetic field has. Muscle tissue absorbs more energies than the other tissue and converts it to heat more effectively. Usually the depth of penetration that RFEMF has is measured in millimeters (mm). However, the greater the frequency, the more shallow the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have discovered that RF-EMF could disrupt the blood-brain barrier which can alter sleep patterns and neurotransmitter levels. Additionally the impacts on the effects of EMF on brain activity are linked to neurodegenerative disorders. For what is emf radiation , EMF from mobile phones could affect the electroencephalogram's activity and sleep patterns, in addition to the activity of nitric oxide and xanthin oxide.
Researchers at Vienna University have studied the effects of exposure to RF-EMF on brain cells. They also looked at what effects ELF EMF on brain system. Though the cellular mechanisms involved are not completely comprehended however, there is an obvious relationship between exposure to ELF EMF and depletion of myelin. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. There are, however, known methods for regenerating myelin within the brain.
Researchers have discovered that exposure to 900 MHz EMF increased the permeability of the BBB and also increased the signs of neuronal damage in rats. what is emf radiation observed increased extravasation of albumin into neurons. Further, they found the following: after 30 mins of 900 MHz exposure 99mTcMIBI increased its penetration in the cortex. However this effect did not occur when using Evans blue-based injections.
However, RF-EMF has no clear mechanism to disrupt the BBB. Evidence suggests that non-thermal EMF exposure may increase erythrocyte cell membrane permeability, which may affect the BBB and enhance the efflux of calcium ions. Moreover, the presence of a 99mTc-MIBI radiotracer in the brain has also been associated with increasing the permeability of BBB.
