Health Effects of EMF Radiation
RF-EMF radiation can cause damage to DNA, heat up of tissues and even disrupt the blood brain barrier. These effects are real and ARPANSA is actively engaged in discussions with EHS community, medical experts, and researchers. ARPANSA will continue to examine research regarding the health effects of EMF radiation.
RF-EMF damages DNA
The exposure to electromagnetic fields created by humans (EMFs) can cause DNA damage, as well as other adverse health adverse effects. EMFs can disrupt intracellular ionic concentrations, which are crucial to maintain the balance of electrochemical activity in cells. This can alter the balance of cell metabolism, resulting to DNA destruction. Additionally exposure to EMFs can cause the production of free radicals and reactive oxygen species (ROS).
Exposure to RF-EMF radiation has been linked with alterations in the development of male germ cells. This involves the differentiation of the germ cell into spermatozoa, as well as functional maturation as the spermatozoa pass across the epididymis. To investigate the effect of RF-EMF exposure on male germ cell development, a specifically-designed waveguide device was developed for the purpose of exposing unrestrained mice to RF-EME in the range of 2.2 W/kg.
In a recent study researchers have discovered that exposure to RF-EME caused the oxidative DNA damage of spermatozoa. Sperm DNA fragmentation increased by 18% after one week of treatment and by 23 percent after five weeks. Furthermore, DNA damage in mitochondria was observed by measuring the level of a biomarker, 8-hydroxy-2-deoxyguanosine (8-OH-dG).
Although the radiation emitted by RF-EMF isn't yet considered to be a carcinogen. However, several studies have shown that RF-EMF exposure can impair DNA integrity in a range of cell lines. In one such study, scientists subjected Vero cells with an EMF at 100 Hz over about 45 minutes. They assessed DNA damage for at 48 hours following exposure to determine if the exposure affected DNA integrity.
RF-EMF causes tissue heating
Although the effects of RF-EMF are typically considered to be thermal, some studies have demonstrated that non-thermal influences are also present. These factors could be responsible 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 an exhaustive review.
what is emf radiation -thermal effects of RF-EMF could be mediated by the cell membrane. This is a field of research that has been extensively studied. In particular the electrochemical behavior of cell membranes has been investigated. Click here! is believed that energy from RF-EMFs greater than 1 MHz is transferred to the tissue through dielectric as well as the dissipation of ions. Previous theoretical analyses indicated that the energy transfer to the tissue could be up to 200 kV/m.
The electrical properties of tissues are controlled through the distribution and composition of water molecules, and other substances in the body. This determines how absorbed RF EMR is by different tissues. The tissues with the highest conductivity tend to absorb more of the field and cause more of an impact. This is why the degree of heating in tissues is not constant between the outside and inside and is only noticeable in hot areas. Bone and fatty tissue are less prone to RF heating than other tissues because they are not as water-based. content.
emf radiation of penetration of the electromagnetic field depends on the strength and frequency that the electromagnetic field has. Muscle tissue absorbs more radiation than most tissues and converts it into heat more effectively. Typically, the depth of penetration that RFEMF has is measured by millimeters (mm). 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. Additionally to this, the effects of EMF affect brain function are linked to neurodegenerative disorders. For instance, EMF from mobile phones can affect electroencephalogram activity and sleep patterns, in addition to the activities of nitric oxide and xanthin oxidase.
Researchers from the Vienna University have studied the effects of RF-EMF exposure to brain cells. They also looked at how ELF EMFs on the brain system. Though the cellular mechanisms that play a role are not fully known however, there is an obvious association between ELF-EMF exposure and myelin depletion. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. However, there are tested methods to regenerate myelin within the brain.
Researchers have discovered that exposure to the frequency of 900 millimeters EMF caused a rise in the permeability of BBB and increased symptoms of neuronal damage in rodents. They also observed an increase in the extravasation of neuronal albumin. Furthermore, they discovered in 30 minutes exposure at 900 MHz 99mTc-MIBI accelerated its permeation to the cerebral cortex. However this effect didn't occur with Evans blue injections.
Despite these findings, RF EMF does not have a clear mechanism for disrupting the BBB. Evidence suggests that non-thermal EMF exposure can increase erythrocyte membrane permeability, which could influence the BBB and enhance the efflux of calcium-ion. Moreover, the presence of a 99mTcMIBI radiotracer inside the brain has also been linked to increasing the permeability and permeability of the BBB.
