The radiation RF-EMF causes damaged DNA, heat to the tissues and disrupt the blood-brain barrier. These effects are real, and ARPANSA is active in collaborating in discussions with EHS communities, medical professionals as well as researchers. The agency will continue study research related to the health effects of EMF radiation.

is emf radiation harmful is caused by RF-EMF
Exposure to man-made electromagnetic fields (EMFs) is associated with DNA damage, as well as other negative health effects. EMFs can affect intracellular ionic concentrations, which are vital to maintain the electrochemical balance of cells. In turn, this can disrupt cell homeostasis, resulting to DNA damage. Additionally, exposure to EMFs is also linked to an increase in the production of free radicals and reactive oxygen species (ROS).
The exposure to radiation from RF-EMF has been linked to changes in male germ cell development. This is due to the transformation of germ cells into spermatozoa, aswell functioning maturation when the spermatozoa travel across the epididymis. To study the effect of RF-EMF exposure on male germ cells, a specially-built waveguide machine was designed for the exposure of unrestrained mice to RF-EMF in the range of 2.2 W/kg.
In a recent study, researchers have discovered that exposure to RF-EME triggered the oxidation of DNA in the spermatozoa. Sperm DNA fragmentation increased by 18% after a 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).
However, RF-EMF radiation is not yet recognized as a true carcinogen. However, numerous studies have shown that RF-EMF exposure can impair DNA health in variety of cell varieties. In one such study researchers were exposed Vero cell lines to EMF that was 100Hz, for 45 minutes. They assessed DNA damage for 48 hours after exposure to determine if the exposure affected DNA integrity.
The effect of RF-EMF on tissue heating
Although the effects of RF-EMF are generally thought as thermal in nature, some studies have demonstrated that non-thermal effects are also evident. These effects may account for certain of the unsolved findings in epidemiological studies of EMF hypersensitivity. Therefore, it is important to consider the non-thermal effects when conducting systematic reviews.
Effects that are not thermal from the RF-EMF can be mediated by the cell membrane. This is a field of research that has been extensively studied. Particularly the electrochemical behavior of cell membranes has been studied. The current understanding is that energy generated by RF-EMF greater than 1 MHz gets transferred to tissues via dielectric and ionic dissipation. Previous theoretical analyses indicated that the energy transfer to the tissue could be up to 200 kV/m.
emf radiation of tissue are controlled through the distribution and composition of water molecules, and other molecules within the body. This determines how absorbent RF EMR is by different tissues. Organs with greater conductivity are likely to absorb more EMR field and produce more of an effect. This is the reason the degree of heating in tissues is not constant between the outside and inside, but occurs in hot spots. Bone and fatty tissues are less prone to RF heating as compared to other tissues, since they are not as water-based. content.
The extent of penetration of the electromagnetic field is determined by the strength and frequency that the electromagnetic field has. Muscle tissue absorbs more field energy than other tissues and transforms it into heat more efficiently. Usually the penetration depth of RF-EMF is measured by millimeters (mm). However, the greater the frequency, the more shallow the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have found that RF-EMF can disrupt the blood-brain barrier changing sleep patterns as well as neurotransmitter levels. Furthermore the impacts that EMF affect brain function have been linked to neurodegenerative diseases. 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 oxide.
emf radiation from the Vienna University have studied the effects of exposure to RF EMF in brain cells. They also examined what effects ELF EMFs on the nervous system. While the mechanisms of the cell aren't completely known however, there is an obvious association between ELF-EMF exposure and depletion of myelin. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. However, there are tested methods to regenerate myelin inside the brain.
Researchers have discovered that exposure to 900 millimeters EMF caused a rise in the permeability of the BBB and increased the signs of neuronal injury in rodents. They also observed an increase in the release of albumin into neurons. Furthermore, they discovered the following: after about 30 min of exposure at 900 MHz 99mTc-MIBI accelerated its permeation into the brain. But, this effect did not happen with Evans blue injections.
Despite these findings, RF-EMF has no clear mechanism for disrupting the BBB. Evidence suggests that non-thermal EMF exposure may increase erythrocyte cell membrane permeability, which could alter the BBB and also increase the efflux of calcium-ion. Additionally, the presence of a 99mTcMIBI radiotracer inside the brain has also been linked to increasing the permeability and permeability of the BBB.
