The radiation RF-EMF causes damage to DNA, heat up of tissues and even disrupt the blood brain barrier. These effects are real and ARPANSA is actively involved with the EHS group, the medical professionals as well as researchers. The agency will continue to study research related to the health impacts of EMF radiation. RF-EMF can cause DNA damage Exposure to man-made electromagnetic fields (EMFs) can cause DNA damage as well as negative health effects. EMFs can alter the intracellular ionic levels that are vital to maintain the balance of electrochemical activity in cells. This can disrupt cell homeostasis, resulting damages to the DNA. Additionally exposure to EMFs can cause an increase in the production of free radicals and reactive oxygen species (ROS). Exposure to RF-EMF radiation has been linked with alterations in the male germ cell's development. This involves the transformation of germ cells into spermatozoa, as well as functional maturation as the spermatozoa pass through the epididymis. To determine the effects of RF-EMF on male germ cell development A specially designed waveguide machine was designed for the exposure of mice without restriction to RF-EMF at 2.2 W/kg. In check it out that was conducted recently, researchers found that exposure to RF-EME caused oxidative DNA damage in spermatozoa. Sperm DNA fragmentation increased by 18% following an entire week of treatment and by 23% after 5 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 classified as a cancer-causing agent. But, several studies have found that RF-EMF exposure can impair DNA health in variety of cell varieties. In one study researchers were exposed Vero cells to an EMF that was 100Hz, for about 45 minutes. They assessed DNA damage for 48 hours after exposure to determine if exposure affected DNA integrity. The RF-EMF effect causes the heating of tissues Although the effects of RF-EMF are usually believed to have thermal origins, some studies have shown that non-thermal influences are also present. These may be the reason for some of the unresolved issues in epidemiological studies on EMF hypersensitivity. It is therefore important to take into account non-thermal effects when conducting a systematic review. The non-thermal effects of RF-EMF could occur at the cell membrane. This is an area which has already been thoroughly examined. Particularly the electrochemical behavior of cell membranes has been investigated. Current understanding suggests that energy from RF-EMF that exceeds 1 MHz is transmitted to the tissue via dielectric and Ionic dissipation. Studies of the theory have suggested that the energy transfer to the tissue could be as high as 200 kV/m. The electric properties of tissue are regulated 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 of the field and cause more of an effect. This is the reason why the amount of heat generated by tissue doesn't increase continuously as it moves from the exterior to, but occurs in hot spots. Bone and fatty tissue is less prone to RF heating as compared to other tissues, since they are low in water content. The depth of the field's penetration is determined by the strength and frequency of the field. Muscle tissue is more able to absorb field energies than the other tissue, and converts it to heat more effectively. Usually the depth of penetration of RF-EMF is measured as millimeters (mm). The higher the frequency, the deeper the penetration. RF-EMF causes blood-brain barrier disruption Researchers have found that RF-EMF can alter the blood-brain-barrier which can alter sleep patterns and neurotransmitter levels. Additionally the impacts on the effects of EMF affect brain function have been associated with neurodegenerative diseases. For example, EMF from mobile phones can alter electroencephalogram activity as well as sleep patterns, and the actions of nitric Oxide and xanthin oxide. Researchers at Vienna University have studied the effects of exposure to RF EMF on brain cells. They also studied what effects ELF EMFs on the nervous system. Although the cellular mechanisms involved are not completely 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. There are, however, known methods for regenerating myelin within the brain. Researchers have discovered that exposure to the frequency of 900 Mhz EMF caused a rise in the permeability of BBB and increased symptoms of neuronal damage in rats. They also observed an increase in the extravasation of albumin into neurons. Additionally, they observed the following: after 30 mins of exposure to 900 MHz 99mTc-MIBI accelerated its penetration in the cortex. However this effect didn't happen with Evans blue-based injections. Despite these findings, RF EMF has no clear mechanism for disrupting the BBB. Research suggests that EMF exposure increases erythrocyte membrane permeability, which may affect the BBB and increase the efflux of calcium-ion. Furthermore, the presence a 99mTc-MIBI radiotracer in the brain has also been associated with increasing the permeability of BBB.
