RF-EMF radiation can cause damages to DNA and tissue and even disrupt the blood-brain barrier. emf radiation are real, and ARPANSA is actively engaged with the EHS group, the medical specialists as well as researchers. The agency will continue examine research regarding the health impacts of EMF radiation.
RF-EMF damages DNA
The exposure to electromagnetic fields created by humans (EMFs) is associated with DNA damage as well as negative health consequences. EMFs can disrupt the intracellular ionic levels, which are vital to maintain the balance of electrochemical activity in cells. It can also disrupt cell homeostasis, resulting to DNA damage. Moreover, exposure to EMFs can also trigger an overproduction of free radicals as well as reactive oxygen species (ROS).
The exposure to radiation from RF-EMF has been linked to changes in the male germ cell's development. This is due to the transformation of germ cells into spermatozoa, aswell functioning maturation when the spermatozoa travel throughout the epididymis. To study the effect of RF-EMF exposure on male germ cells, a specially-built waveguide machine was designed to expose unrestrained mice to RF-EMF with a dose of 2.2 W/kg.
In a recent study researchers discovered that exposure to RF-EME triggered oxidative DNA damage in the spermatozoa. Sperm DNA fragmentation increased by 18% after one week of treatment and by 23 percent 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 considered a carcinogen. However, numerous studies have revealed that exposure to RF-EMF can affect DNA integrity in a range of cell varieties. In one study researchers were exposed Vero cell lines to EMF of 100 Hz for 45 minutes. They evaluated DNA damage at 48 hours following exposure to determine if the exposure affected the integrity of DNA.
RF-EMF causes emf radiation heating
While the effects of RF-EMF are typically considered to have thermal origins, a few studies have shown that non-thermal influences are also observed. These factors could be responsible for some of the unsolved issues in epidemiological studies of EMF hypersensitivity. It is therefore important to take into account non-thermal effects when conducting a systematic review.
Effects that are not thermal from RF-EMF may occur at the cell membrane. This is an area which has already been extensively studied. Particularly the electrochemical behavior of cell membranes has been investigated. It is believed that RF-EMF energy higher than 1 MHz is transmitted into the tissues through dielectric and ionic dissipation. The theoretical studies have indicated that the energy transferred to tissues could be as high as 200 kV/m.
The electric properties of tissue are regulated in the form and quantity of water molecules and ions, and other molecules within the body. This determines how well absorbed RF EMR is by different tissues. The tissues with the highest conductivity tend to absorb more of the EMR field and produce more of an impact. This is the reason why the amount of heat generated by tissue does not increase steadily from outside to inside the body however, it is more prevalent in hot areas. Bone and fatty tissue is less prone to RF heating as compared to other tissues, since they have a low water content.
The depth of penetration of the electromagnetic field depends on the strength and frequency of the field. Muscle tissue absorbs more field energies than the other tissue and converts it to heat more efficiently. Usually the penetration depth that RFEMF has is measured as millimeters (mm). The greater the frequency, the deeper the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have found that RF EMF could disrupt the blood-brain barrier, altering sleep patterns and neurotransmitter levels. Furthermore to this, the effects that EMF affect brain function are associated with neurodegenerative disorders. For https://barbertwist9.doodlekit.com/blog/entry/25038953/health-effects-of-emf-radiation , EMF from mobile phones can affect electroencephalogram activity and sleep patterns, and the activity of nitric oxide and xanthin oxidase.
Researchers at Vienna University have studied the effects of RF-EMF exposure on brain cells. They also examined the effects of ELF EMFs on the nervous system. While the mechanisms of the cell that are involved aren't fully known but 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, proven methods for regenerating myelin in the brain.
Researchers have observed that exposure to 900 Mhz EMF enhanced the permeability of the BBB and increased symptoms of neuronal damage in rats. They also observed an increase in the release of albumin to neurons. Furthermore, they discovered the following: after about 30 min of 900 MHz exposure 99mTc-MIBI accelerated its penetration in the cortex. However this effect didn't occur when using Evans blue-based injections.
Despite these findings, RF EMF has no clear mechanism for disrupting the BBB. Research suggests that EMF exposure can increase erythrocyte membrane permeability, which may influence the BBB and also increase calcium ion efflux. Additionally, the presence of a 99mTc-MIBI radiotracer in the brain has been connected to increasing the permeability of the BBB.
