Well being Effects of EMF Radiation
emf radiation symptoms RF-EMF causes damages to DNA and tissue and even disrupt the blood-brain barrier. These effects are real and ARPANSA is actively engaged with the EHS group, the medical professionals and researchers. The agency will continue review research on the health effects caused by EMF radiation.
DNA damage is caused by RF-EMF
Exposure to man-made electromagnetic fields (EMFs) can cause DNA damage, as well as other negative health effects. EMFs can disrupt the intracellular ionic concentrations that are vital to maintain the electrochemical balance of cells. It can also alter the balance of cell metabolism, resulting in DNA damage. Moreover, 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 results in the differentiation of the germ cell into spermatozoa, aswell functioning maturation when the spermatozoa travel throughout the epididymis. To investigate the effects of RF-EMF on male germ cell development, a specifically-designed waveguide machine was constructed to expose non-restrained mice to RF-EME in the range of 2.2 W/kg.
In a recent study researchers found that exposure to RF-EME caused an oxidative DNA damage to the spermatozoa. Sperm DNA fragmentation increased by 18% following 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 the fact that RF-EMF radiation isn't yet considered a carcinogen. However, numerous studies have found that RF-EMF exposure can impair DNA health in variety of cell lines. In is emf radiation harmful , scientists subjected Vero cells to an EMF of 100 Hz for about 45 minutes. They measured DNA damage at 48 hours following exposure to determine if the exposure had a negative effect on DNA integrity.
The effect of RF-EMF on tissue heating
Although the effects of RF-EMF are usually believed to be thermal, some studies have shown that non-thermal influences are also present. These may be the reason for certain of the unsolved findings in the epidemiological study of EMF hypersensitivity. This is why it is crucial to take into account non-thermal effects when conducting a systematic review.
Effects that are not thermal from RF-EMF may occur on the cell's membrane. This is an area of research that has been extensively investigated. In particular the electrochemical behavior of cell membranes has been studied. Current understanding suggests that RF-EMF energy higher than 1 MHz is transferred to tissues via dielectric and ionic dissipation. Studies of the theory have suggested that the energy transferred to the tissue could be as high as 200 kV/m.
The electrical properties of tissues are regulated through the distribution and composition of water molecules, and other molecules inside the body. This determines how absorbent EMR RF is by various tissues. Organs with greater conductivity are likely to absorb more of the field and cause more of an effect. This is the reason the degree of heating in tissues doesn't increase continuously from outside to inside the body, but occurs in hot areas. Bone and fatty tissue are less susceptible to heating by RF as compared to other tissues, since they have a low water content.
The intensity of penetration of the electromagnetic field is determined by the frequency and strength that the electromagnetic field has. Muscle tissue is more able to absorb field energy than other tissues and converts it into heat more effectively. Typically the depth of penetration for RF EMF is determined as 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, altering sleep patterns and neurotransmitter levels. Additionally to this, the effects of EMF affect brain function have been linked to neurodegenerative diseases. For instance, EMF from mobile phones can alter electroencephalogram activity as well as sleep patterns, as well as the actions of nitric Oxide and xanthin oxidase.
Researchers from the Vienna University have studied the effects of RF-EMF exposure in brain cells. They also studied the effects of ELF EMF on nervous system. Though the cellular mechanisms that are involved aren't fully understood, there is a clear connection between exposure to ELF-EMF and depletion of myelin. emf radiation might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. Fortunately, there are some tested methods to regenerate myelin within the brain.
Researchers have observed that exposure to 900 millimeters 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 exposure to 900 MHz, 99mTc-MIBI increased its permeation into the brain. However, this effect did not occur when using Evans blue-based injections.
Despite these findings, RF-EMF is not able to provide a definitive mechanism to disrupt the BBB. Research suggests that EMF exposure increases erythrocyte membrane permeability, which could alter the BBB and enhance calcium ion efflux. Furthermore, the presence a 99mTc-MIBI radiotracer in the brain has also been linked to increasing the permeability and permeability of the BBB.
