Health Effects of EMF Radiation
The radiation RF-EMF causes damaged DNA, heat to the tissues, and can disrupt the blood-brain-barrier. These are real-world effects, and ARPANSA is actively engaged within the EHS group, the medical experts and researchers. The agency will continue study research related to the health effects caused by EMF radiation.
RF-EMF damages DNA
Exposure to man-made electromagnetic fields (EMFs) is associated with DNA damage, as well as other health effects. EMFs can affect the intracellular ionic levels, which are vital to maintain the electrochemical balance of cells. It can also disrupt cell homeostasis, resulting to DNA damage. Moreover exposure to EMFs is also linked to an overproduction of free radicals and reactive oxygen species (ROS).
Exposure to RF-EMF radiation has been associated with changes in male germ cell development. This is due to the differentiation of the germ cell into spermatozoa as well as functional maturation as the spermatozoa pass through the epididymis. To determine the sensitivity of RF-EMF exposure to male germ cell development, a specially-built waveguide machine was designed to expose non-restrained mice to RF-EME in the range of 2.2 W/kg.
In a recent study, researchers discovered exposure to RF-EME causes the oxidation of DNA in spermatozoa. Sperm DNA fragmentation increased by 18% following one 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).
Despite this it isn't yet considered a carcinogen. But, emf radiation symptoms have found that RF-EMF exposure can impair the integrity of DNA in variety of cell types. In one study researchers were exposed Vero cells with an EMF of 100 Hz for about 45 minutes. They evaluated DNA damage at 48 hours following exposure to determine whether the exposure had a negative effect on DNA integrity.
The RF-EMF effect causes the heating of tissues
Although the effects of RF EMF are generally thought to have thermal origins, some studies have shown that non-thermal influences are also evident. These effects may account for certain of the unsolved findings in epidemiological studies on EMF hypersensitivity. This is why it is crucial to consider the non-thermal effects when conducting systematic reviews.
Non-thermal effects from the RF-EMF can occur on the cell's membrane. This is a field of research that has been thoroughly examined. In particular the electrochemical behavior of cell membranes has been studied. Current understanding suggests that energy generated by RF-EMF greater than 1 MHz is transferred into the tissues through dielectric and ionic dissipation. The theoretical studies have indicated that the energy that is transferred to the tissue could be up to 200 kV/m.
The electric properties of tissues 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. Organs with greater conductivity are likely to absorb more field, and thus cause more of an effect. This is why the level of tissue heating is not constant from outside to inside the body and is only noticeable in hot areas. Bone and fatty tissue is less prone to RF heating than other tissues, because they are not as water-based. content.
The depth of the field's electromagnetic energy is determined by the frequency and strength of the field. Muscle tissue absorbs more radiation than most tissues and converts it into heat more efficiently. Usually the depth of penetration for RF EMF is determined in millimeters (mm). The higher the frequency, the more shallow 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. Furthermore to this, the effects of EMF in brain activities are associated with neurodegenerative diseases. For example, EMF from mobile phones can alter electroencephalogram activity as well as 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 in brain cells. emf radiation studied what effects ELF EMF on nervous system. While the mechanisms of the cell aren't completely understood however, there is an obvious connection between exposure to ELF-EMF and depletion of myelin. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. However, there are known methods to regenerate myelin in the brain.
Researchers have found that exposure to the frequency of 900 Mhz EMF enhanced the permeability of the BBB and raised symptoms of neuronal damage in rats. emf radiation observed an increase in the extravasation of albumin to neurons. Additionally, they observed in 30 minutes 900 MHz exposure, 99mTc-MIBI increased its diffusion in the cortex. However this effect didn't occur when using Evans blue-based injections.
Despite these findings, RF EMF is not able to provide a definitive mechanism for disrupting the BBB. Research suggests that EMF exposure may increase erythrocyte cell membrane permeability, which could affect the BBB and increase the efflux of calcium-ion. Furthermore, the presence a 99mTc-MIBI radiotracer within the brain is also linked to increasing the permeability of the BBB.
