Health Effects of EMF Radiation
The radiation RF-EMF causes DNA damage, tissue heating, and disrupt the blood-brain barrier. These effects are real, and ARPANSA is active in collaborating with the EHS communities, medical specialists, and researchers. emf radiation will continue examine research regarding the health impacts of EMF radiation.
RF-EMF damages DNA
Exposed to man-made electromagnetic fields (EMFs) can cause DNA damage and other adverse health consequences. EMFs can disrupt the intracellular ionic levels, which are crucial to maintain the balance of electrochemical activity in cells. This can alter the balance of cell metabolism, resulting damages to the DNA. Moreover exposure to EMFs is also associated with the production 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. emf radiation results in the development of germ cells into spermatozoa, aswell functional maturation when 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 exposure of mice that were not restrained to RF-EME in the range of 2.2 W/kg.
In a recent study researchers have discovered that exposure to RF EME caused an oxidative DNA injury in spermatozoa. Sperm DNA fragmentation increased by 18% following a 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, RF-EMF radiation is not yet considered to be a carcinogen. However, several studies have found that exposure to RF-EMF radiation can damage DNA health in variety of cell types. In one study, scientists subjected Vero cell lines to EMF at 100 Hz over about 45 minutes. They assessed DNA damage for within 48 hours of exposure to determine whether the exposure affected DNA integrity.
RF-EMF causes tissue heating
Although the effects of RF-EMF are typically considered to have thermal origins, some studies have shown that non-thermal effects may also be present. These effects may account for some of the unresolved observations in epidemiological studies on EMF hypersensitivity. Therefore, it is important to take into account 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 an area where research has been extensively investigated. Particularly, the electrochemical behavior of cell membranes has been studied. what is emf radiation is that RF-EMF energy higher than 1 MHz is transferred to tissue through dielectric and the dissipation of ions. The theoretical studies have indicated that the energy transfer to the tissue could be up to 200 kV/m.
The electrical properties of tissues are regulated through the distribution and composition of water molecules and other molecules in the body. This determines how absorbed 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 effect. This is why the level of heat generated by tissue does not increase steadily as it moves from the exterior to, but occurs in hot spots. Bone and fatty tissue is less susceptible to heating by RF as compared to other tissues, since they have a low water content.
The intensity of the field's penetration is determined by the strength and frequency of the field. Muscle tissue absorbs more field energy than other tissues and transforms it into heat more efficiently. Typically the penetration depth that RFEMF has is measured in millimeters (mm). But, the greater the frequency, the shallower 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. Furthermore the impacts of EMF affect brain function have been associated with neurodegenerative disorders. For instance, EMF from mobile phones could affect the electroencephalogram's activity and sleep patterns, in addition to the actions of nitric Oxide and xanthin oxidase.
Researchers at Vienna University have studied the effects of exposure to RF-EMF on brain cells. They also studied what effects ELF EMF on the brain system. Though the cellular mechanisms that play a role are not fully understood 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. Fortunately, there are some proven methods for regenerating myelin in the brain.
Researchers have found that exposure to frequencies of 900 millimeters EMF increased the permeability of BBB and increased symptoms of neuronal damage in rodents. They also observed increased exovasation of neuronal albumin. Furthermore, they discovered that after 30 minutes of exposure to 900 MHz 99mTcMIBI increased its penetration in the cortex. But this effect didn't occur when using Evans blue-based injections.
Despite these findings, RF-EMF has no clear method for disrupting the BBB. Evidence suggests that non-thermal EMF exposure can increase erythrocyte membrane permeability. This could alter the BBB and enhance calcium ion efflux. Furthermore, the presence a 99mTcMIBI radiotracer inside the brain has also been connected to increased permeability of the BBB.
