The radiation from RF-EMF can cause damaged DNA, heat to the tissues, and even disrupt the blood-brain barrier. These effects are real, and ARPANSA is actively engaged in discussions with EHS communities, medical experts, and researchers. The agency will continue study research related to the health effects caused by EMF radiation.
RF-EMF damages DNA
The exposure to electromagnetic fields created by humans (EMFs) can cause DNA damage as well as adverse health consequences. EMFs can affect the intracellular ionic levels, which are essential to ensure the balance of electrochemical activity in cells. It can also alter the balance of cell metabolism, resulting to DNA damage. Moreover, exposure to EMFs is also associated with an overproduction of free radicals and reactive oxygen species (ROS).
what is emf radiation to RF-EMF radiation has been linked to changes in the male germ cell's development. This involves the differentiation of the germ cell into spermatozoa as well maturation of the functional aspect as spermatozoa move throughout the epididymis. To determine the effect of RF-EMF exposure on male germ cell development A specially designed waveguide machine was constructed to expose unrestrained mice to RF-EMF in the range of 2.2 W/kg.
In a recent study researchers have discovered exposure to RF-EME causes an oxidative DNA damage to the spermatozoa. Sperm DNA fragmentation was increased by 18% after one 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).
Despite this it isn't yet considered a carcinogen. But, numerous studies have shown that RF-EMF exposure can impair DNA health in range of cell varieties. In one such study researchers subjected Vero cells with an EMF of 100 Hz for about 45 minutes. They assessed DNA damage for 48 hours after exposure to determine if exposure had a negative effect on DNA integrity.
The RF-EMF effect causes the heating of tissues
Although the effects of RF-EMF are typically believed to be thermal, a few studies have revealed that non-thermal effects may also be present. These factors could be responsible for certain of the unsolved findings in epidemiological studies of EMF hypersensitivity. Therefore, it is important to consider the non-thermal effects when conducting a systematic review.
Non-thermal effects from RF-EMF may occur at the cell membrane. This is an area of research that has been extensively examined. Particularly the electrochemical behavior of cell membranes is being studied. The current understanding is that RF-EMF energy higher than 1 MHz is transferred into the tissues through dielectric dissipation and ionic discharge. The theoretical studies have indicated that the energy transfer to tissues 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 inside the body. This determines how absorbed EMR RF is by various tissues. Organs with greater conductivity are likely to absorb more field, and thus cause more of an effect. This is the reason the degree of tissue heating doesn't increase continuously from outside to inside and is only noticeable in hot areas. Bone and fatty tissues are less susceptible to heating by RF than other tissues, because they are not as water-based. content.
The extent of the field's penetration depends on the strength and frequency of the field. Muscle tissue absorbs more field energy than other tissues, and converts it to heat more efficiently. Typically the depth of penetration of RF-EMF is measured in millimeters (mm). The higher the frequency, the shallower the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have found that RF-EMF could disrupt the blood-brain barrier changing sleep patterns as well as neurotransmitter levels. Furthermore, the effects that EMF affect brain function are associated with neurodegenerative disorders. For instance, EMF from mobile phones can affect electroencephalogram activity and sleep patterns, and the activity of nitric oxide and xanthin oxidase.
Researchers at the Vienna University have studied the effects of RF-EMF exposure to brain cells. They also looked at the effects of ELF EMF on the nervous system. While the mechanisms of the cell that are involved aren't fully understood, there is a clear connection between exposure to ELF-EMF and myelin depletion. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. Fortunately, there are some proven methods for regenerating myelin inside the brain.
Researchers have discovered that exposure to frequencies of 900 millimeters EMF enhanced the permeability of the BBB and caused an increase in the signs of neuronal injury in rodents. emf radiation observed increased extravasation of albumin into neurons. Furthermore, they discovered that after 30 minutes of exposure at 900 MHz, 99mTc-MIBI increased its penetration into the brain. However this effect didn't happen with Evans blue-based injections.
However, RF-EMF does not have a clear mechanism for disrupting the BBB. The evidence suggests that nonthermal EMF exposure can increase erythrocyte membrane permeability, which could affect the BBB and also increase the efflux of calcium-ion. Furthermore, the presence a 99mTc-MIBI radiotracer in the brain has also been associated with an increase in the permeability and permeability of the BBB.
