what is emf radiation -EMF causes damaged DNA, heat to the tissues, and disrupt the blood-brain barrier. These effects are real and ARPANSA is actively engaged within the EHS communities, medical specialists and researchers. The agency will continue to study research related to the health impacts of EMF radiation.
RF-EMF damages DNA
The exposure to electromagnetic fields created by humans (EMFs) can cause DNA damage as well as health adverse effects. EMFs can disrupt the intracellular ionic levels, which are essential to ensure a cell's electrochemical balance. It can also alter the balance of cell metabolism, resulting damages to the DNA. Furthermore exposure to EMFs can also trigger an increase in the production of free radicals as well as reactive oxygen species (ROS).
The exposure to radiation from RF-EMF has been linked to changes in male germ cells' development. This results in the development of germ cells into spermatozoa, as well maturation of the functional aspect as spermatozoa move across the epididymis. To investigate the effect of RF-EMF exposure on the development of male germ cells A specially designed waveguide machine was designed to expose unrestrained mice to RF-EME in the range of 2.2 W/kg.
In a recent study, researchers discovered that exposure to RF-EME triggered an oxidative DNA damage to the spermatozoa. Sperm DNA fragmentation was increased by 18% after a 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).
Despite this it isn't yet considered to be a carcinogen. However, emf radiation symptoms have found that RF-EMF exposure can impair DNA integrity in a range of cell varieties. In one study, scientists exposed Vero cells with an EMF of 100 Hz for 45 minutes. They assessed DNA damage for at 48 hours following exposure to determine if exposure affected the integrity of DNA.
The effect of RF-EMF on tissue heating
While the effects of RF-EMF are generally believed to have thermal origins, some studies have revealed that non-thermal effects are also evident. These may be the reason for certain of the unsolved findings 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 may occur at the cell membrane. emf radiation symptoms is a field of research that has been thoroughly examined. Particularly the electrochemical behavior of cell membranes has been studied. The current understanding is that energy generated by RF-EMF greater 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 up to 200 kV/m.
The electric properties of tissue are regulated through the distribution and composition of water molecules, and other molecules in 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 thus cause more of an impact. This is the reason why the amount of heating in tissues is not constant from outside to inside and is only noticeable in hot spots. Bone and fatty tissues are less prone to RF heating than other tissues because they are low in water content.
The intensity of penetration of the electromagnetic field is determined by the strength and frequency of the field. Muscle tissue is more able to absorb field radiation than most tissues and transforms it into heat more efficiently. Usually the penetration depth that RFEMF has is measured by millimeters (mm). But, the higher the frequency, the deeper the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have discovered that RF-EMF could disrupt the blood-brain barrier which can alter sleep patterns and neurotransmitter levels. Additionally to this, the effects that EMF affect brain function are linked to neurodegenerative disorders. For example, EMF from mobile phones could affect the electroencephalogram's activity and sleep patterns, in addition to the activities of nitric oxide and xanthin oxide.
Researchers from the Vienna University have studied the effects of RF-EMF exposure to brain cells. They also examined the effects of ELF EMFs on the brain system. While the mechanisms of the cell involved are not completely known, there is a clear relationship between exposure to ELF EMF and depletion of myelin. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. However, there are tested methods to regenerate myelin in the brain.
Researchers have found that exposure to 900 MHz EMF caused a rise in the permeability of the BBB and caused an increase in the signs of neuronal injury in rodents. They also observed an increase in the extravasation of albumin to neurons. Additionally, they observed in 30 minutes 900 MHz exposure 99mTc-MIBI accelerated its penetration to the cerebral cortex. However, this effect did not happen with Evans blue-based injections.
However, RF-EMF does not have a clear mechanism for disrupting 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 been connected to increased permeability of the BBB.
