is emf radiation harmful RF-EMF causes DNA damage, tissue heating, and can disrupt the blood-brain-barrier. These effects are real and ARPANSA is actively involved within the EHS group, the medical experts as well as researchers. The agency will continue review research on the health effects of EMF radiation.
DNA damage is caused by RF-EMF
exposed to electromagnetic fields that are created by man (EMFs) is associated with DNA damage and other negative health consequences. EMFs can disrupt intracellular ionic concentrations, which are crucial to maintain a cell's electrochemical balance. This can alter the balance of cell metabolism, resulting in DNA damage. Furthermore, exposure to EMFs is also linked to an increase in the production of free radicals as well as reactive oxygen species (ROS).
Exposure to RF-EMF radiation has been associated with changes in the male germ cell's development. This results in the differentiation of the germ cell into spermatozoa, aswell functioning maturation when the spermatozoa travel across the epididymis. To investigate the effects of RF-EMF on the development of male germ cells A specially 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 have discovered exposure to RF-EME causes oxidative DNA damage in the spermatozoa. Sperm DNA fragmentation increased by 18% after one week of treatment and by 23% after five weeks. Furthermore, DNA damage in mitochondria was observed by measuring the level of a biomarker, 8-hydroxy-2-deoxyguanosine (8-OH-dG).
Despite this it isn't yet considered to be a carcinogen. However, several studies have revealed that RF-EMF exposure can impair the integrity of DNA in range of cell lines. In one of these studies, scientists exposed Vero cells with an EMF that was 100Hz, for about 45 minutes. They assessed DNA damage for within 48 hours of exposure to determine if exposure affected DNA integrity.
RF-EMF causes tissue heating
Although the effects of RF EMF are generally thought to be thermal, a few studies have shown that non-thermal influences are also evident. These may be the reason for certain of the unsolved findings in the epidemiological study of EMF hypersensitivity. It is therefore important to look at the non-thermal aspects when conducting systematic reviews.
Effects that are not thermal from RF-EMF may be mediated by the cell membrane. This is an area of research that has been extensively studied. In particular the electrochemical properties of cell membranes has been investigated. It is believed that energy generated by RF-EMF greater than 1 MHz is transferred to the tissue via dielectric dissipation and ionic discharge. The theoretical studies have indicated that the energy that is transferred to the tissue could be as high as 200 kV/m.
The electrical properties of tissues are controlled by the composition and distribution of water molecules, ions, and other molecules in the body. This determines how absorbent RF EMR is by different tissues. Tissues with higher conductivity tend to absorb more EMR field and produce more of an effect. This is the reason the degree of tissue heating is not constant from outside to inside, but occurs in hot areas. Bone and fatty tissue are less susceptible to RF heating than other tissues, because they are low in water content.
emf radiation symptoms of the field's penetration is determined by the strength and frequency of field. Muscle tissue absorbs more field radiation than most tissues, and transforms it into heat more effectively. Usually, the depth of penetration of RF-EMF is measured in millimeters (mm). The higher the frequency, the more shallow the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have found 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 in brain activities are linked to neurodegenerative disorders. For instance, EMF from mobile phones can alter electroencephalogram activity as well as sleep patterns, and the activity of nitric oxide and xanthin oxidase.
Researchers at Vienna University have studied the effects of exposure to RF EMF in brain cells. They also examined how ELF EMFs on the brain system. Although the cellular mechanisms that are involved aren't fully known, there is a clear connection between exposure to ELF-EMF and depletion of myelin. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. Fortunately, there are some tested methods to regenerate myelin in the brain.
Researchers have observed that exposure to the frequency of 900 millimeters EMF increased the permeability of BBB and increased the signs of neuronal injury in rodents. They also observed an increase in the release of albumin into neurons. Additionally, they observed that after 30 minutes of exposure at 900 MHz 99mTcMIBI increased its diffusion to the cerebral cortex. But, this effect did not occur when using Evans blue-based injections.
Despite these findings, RF EMF has no clear method for disrupting the BBB. what is emf radiation suggests that non-thermal EMF exposure increases erythrocyte membrane permeability, which could influence the BBB and enhance calcium ion efflux. Furthermore, the presence a 99mTc-MIBI radiotracer in the brain has also been connected to increasing the permeability of BBB.
