The radiation from RF-EMF can cause damaged DNA, heat to the tissues, and disrupt the blood-brain barrier. These effects are real, and ARPANSA is active in collaborating in discussions with EHS group, the medical experts as well as researchers. The agency will continue examine research regarding the health effects caused by EMF radiation.
RF-EMF causes DNA damage
exposed to electromagnetic fields that are created by man (EMFs) can cause DNA damage as well as health consequences. EMFs can disrupt intracellular ionic concentrations, 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. Furthermore, exposure to EMFs is also associated with the production of free radicals as well as reactive oxygen species (ROS).
Exposure to RF-EMF radiation has been linked to changes in male germ cells' development. This involves the differentiation of the germ cell into spermatozoa as well as functional maturation as the spermatozoa travel through the epididymis. To investigate the effect of RF-EMF exposure on male germ cells A specially designed waveguide device was developed to expose unrestrained mice to RF-EME with a dose of 2.2 W/kg.
In a recent study, researchers found that exposure to RF-EME caused oxidative DNA damage in the spermatozoa. Sperm DNA fragmentation 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 the fact that RF-EMF radiation isn't yet recognized as a true carcinogen. But, numerous studies have revealed that exposure to RF-EMF radiation can damage DNA integrity in a variety of cell varieties. In one of these studies researchers subjected Vero cells with an EMF of 100 Hz for 45 minutes. emf radiation assessed DNA damage for within 48 hours of exposure to determine if exposure had a negative effect on DNA integrity.
RF-EMF causes tissue heating
Although the effects of RF-EMF are typically considered to have thermal origins, some studies have demonstrated that non-thermal effects are also observed. These effects may account for certain of the unsolved findings in epidemiological studies of EMF hypersensitivity. It is therefore important to consider the non-thermal effects when conducting systematic reviews.
Non-thermal effects from the RF-EMF can be mediated by the cell membrane. This is an area where research has been extensively studied. Particularly the electrochemical properties of cell membranes has been studied. Current understanding suggests that RF-EMF energy higher than 1 MHz is transferred to tissues via dielectric dissipation and ionic discharge. Studies of the theory have suggested that the energy that is transferred to tissues could be as high as 200 kV/m.
emf radiation symptoms of tissue are regulated in the form and quantity of water molecules and ions, and other molecules within the body. This determines how absorbed RF EMR is by different 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 tissue heating is not constant as it moves from the exterior to, but occurs in hot spots. Bone and fatty tissue is 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 frequency and strength of field. Muscle tissue absorbs more field energy than other tissues and converts it to heat more effectively. Typically the penetration depth of RF-EMF is measured by millimeters (mm). The higher the frequency, the more shallow 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. Additionally, the effects that EMF on brain activity are associated with neurodegenerative diseases. For instance, EMF from mobile phones can alter electroencephalogram activity as well as sleep patterns, in addition to 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. They also examined how ELF EMF on brain system. Although the cellular mechanisms aren't completely understood but 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. There are, however, proven methods for regenerating myelin within the brain.
Researchers have discovered that exposure to the frequency of 900 Mhz EMF enhanced the permeability of the BBB and increased symptoms of neuronal damage in rodents. They also observed an increase in the extravasation of neuronal albumin. Additionally, they observed in 30 minutes exposure at 900 MHz 99mTcMIBI increased its permeation in the cortex. However this effect didn't occur when using Evans blue-based injections.
Despite these findings, RF EMF has no clear method for disrupting the BBB. what is emf radiation suggests that non-thermal EMF exposure can increase erythrocyte membrane permeability, which may alter the BBB and enhance the efflux of calcium ions. Furthermore, the presence a 99mTc-MIBI radiotracer within the brain has been connected to an increase in the permeability of the BBB.
