The radiation RF-EMF causes damaged DNA, heat to the tissues, and can disrupt the blood-brain-barrier. These effects are real and ARPANSA is active in collaborating within the EHS community, medical professionals, and researchers. The agency will continue examine research regarding the health impacts of EMF radiation. DNA damage is caused by RF-EMF The exposure to electromagnetic fields created by humans (EMFs) are associated with DNA damage and other health adverse effects. EMFs can alter the intracellular ionic concentrations that are vital to maintain the balance of electrochemical activity in cells. This can disrupt cell homeostasis, resulting damages to the DNA. Moreover, exposure to EMFs is also linked to the production of free radicals as well as reactive oxygen species (ROS). check here to radiation from RF-EMF has been associated with changes in the male germ cell's development. This is due to the development of germ cells into spermatozoa, as well functioning maturation when the spermatozoa move through the epididymis. To investigate the sensitivity of RF-EMF exposure to male germ cell development A specially designed waveguide machine was designed to expose non-restrained mice to RF-EMF in the range of 2.2 W/kg. In a recent study, researchers discovered that exposure to RF-EME triggered the oxidation of DNA in the spermatozoa. Sperm DNA fragmentation was 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). However it isn't yet considered to be a carcinogen. But, numerous studies have revealed that exposure to RF-EMF radiation can damage the integrity of DNA in range of cell varieties. In one of these studies, scientists subjected Vero cells with an EMF of 100 Hz for 45 minutes. They measured DNA damage 48 hours after exposure to determine if exposure affected the integrity of DNA. RF-EMF causes tissue heating Although the effects of RF-EMF are typically considered to be thermal, some studies have demonstrated that non-thermal effects may also be observed. These factors could be responsible for certain of the unsolved findings in the epidemiological study of EMF hypersensitivity. Therefore, it is important to take into account non-thermal effects when conducting a systematic review. Effects that are not thermal from RF-EMF could occur on the cell's membrane. This is a field which has already been thoroughly examined. Particularly 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 tissues via dielectric and ionic dissipation. The theoretical studies have indicated that the energy that is transferred to tissues could be up to 200 kV/m. The electrical properties of tissues are regulated in the form and quantity of water molecules and ions, and other molecules inside the body. This determines how well absorbed EMR RF is by various tissues. Tissues with higher conductivity tend to absorb more of the EMR field and produce more of an impact. This is the reason the degree of heat generated by tissue doesn't increase continuously from outside to inside the body however, it is more prevalent in hot spots. Bone and fatty tissues are less prone to RF heating than other tissues, because they have a low water content. The depth of the field's penetration is determined by the frequency and strength that the electromagnetic field has. Muscle tissue absorbs more field radiation than most tissues, and converts it into heat more effectively. Usually the depth of penetration that RFEMF has is measured as millimeters (mm). But, the higher the frequency, the shallower the penetration. RF-EMF causes blood-brain barrier disruption Researchers have found that RF-EMF can alter the blood-brain-barrier changing sleep patterns as well as neurotransmitter levels. In addition, the effects that EMF in brain activities are associated with neurodegenerative diseases. For instance, EMF from mobile phones can affect electroencephalogram activity and sleep patterns, as well as the activity of nitric oxide and xanthin oxidase. Researchers from the Vienna University have studied the effects of exposure to RF EMF on brain cells. They also examined what effects ELF EMF on the brain system. Though the cellular mechanisms that are involved aren't fully comprehended, 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. There are, however, tested methods to regenerate myelin within the brain. Researchers have found that exposure to 900 Mhz EMF enhanced the permeability of the BBB and caused an increase in signs of neuronal damage in rats. They also observed an increase in the release of neuronal albumin. Further, they found that after 30 minutes of 900 MHz exposure, 99mTc-MIBI increased its diffusion in the cortex. But, this effect did not happen with Evans blue-based injections. Despite these findings, RF-EMF is not able to provide a definitive method for disrupting the BBB. The evidence suggests that nonthermal EMF exposure may increase erythrocyte cell membrane permeability, which may alter the BBB and increase calcium ion efflux. Furthermore, the presence a 99mTc-MIBI radiotracer in the brain has also been associated with increased permeability of BBB.
