The radiation RF-EMF causes damage to DNA, heat up of tissues and even disrupt the blood brain barrier. These effects are real and ARPANSA is active in collaborating within the EHS group, the medical specialists as well as researchers. ARPANSA will continue to examine research regarding the health effects of EMF radiation.
RF-EMF damages DNA
Exposed to man-made electromagnetic fields (EMFs) are associated with DNA damage as well as adverse health consequences. EMFs can disrupt the intracellular ionic levels, which are vital to maintain a cell's electrochemical balance. This can alter the balance of cell metabolism, resulting damages to the DNA. Furthermore, exposure to EMFs is also associated with an overproduction of free radicals as well as reactive oxygen species (ROS).
emf radiation to radiation from RF-EMF has been associated with changes in male germ cell development. This is due to the transformation of germ cells into spermatozoa, as well functioning maturation as spermatozoa travel throughout the epididymis. To investigate the effect of RF-EMF exposure on the development of male germ cells, a specially-built waveguide device was developed to expose mice that were not restrained to RF-EME in the range of 2.2 W/kg.
In a recent study, researchers discovered that exposure to RF EME caused oxidative DNA damage in spermatozoa. Sperm DNA fragmentation was increased by 18% after an entire week of treatment and by 23% 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, RF-EMF radiation is not yet classified as a cancer-causing agent. However, numerous studies have found that RF-EMF exposure can impair the integrity of DNA in range of cell varieties. In one of these studies, scientists subjected Vero cell lines to EMF at 100 Hz over about 45 minutes. They measured DNA damage at 48 hours following exposure to determine whether the exposure affected DNA integrity.
The effect of RF-EMF on tissue heating
Although the effects of RF-EMF are usually believed as thermal in nature, some studies have demonstrated that non-thermal effects may also be observed. These effects may account for certain of the unsolved findings in epidemiological studies on EMF hypersensitivity. Therefore, it is important to look at the non-thermal aspects when conducting an extensive review.
The non-thermal effects that RF-EMF can have may be mediated by the cell membrane. This is a field of research that has been extensively investigated. In particular the electrochemical behavior of cell membranes has been investigated. It is believed that RF-EMF energy that exceeds 1 MHz is transmitted to the tissue through dielectric and Ionic dissipation. The theoretical studies have indicated that the energy that is transferred to tissues could be as high as 200 kV/m.
what is emf radiation of tissues are regulated in the form and quantity of water molecules and ions, and other molecules in the body. https://ctxt.io/2/AACQ4rfmEQ determines how absorbent RF EMR is by different tissues. Tissues with higher conductivity tend to absorb more field, and thus cause more of an effect. This is the reason why the amount of heating in tissues is not constant between the outside and inside the body and is only noticeable in hot areas. Bone and fatty tissues are less prone to RF heating than other tissues because they are low in water content.
The depth of penetration of the electromagnetic field is determined by the strength and frequency that the electromagnetic field has. Muscle tissue absorbs more radiation than most tissues, and converts it into heat more efficiently. Usually the penetration depth for RF EMF is determined as millimeters (mm). The higher the frequency, deeper the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have found that RF-EMF can alter the blood-brain-barrier change sleep patterns as well as neurotransmitter levels. Furthermore to this, the effects of EMF affect brain function have been linked to 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 from the Vienna University have studied the effects of RF-EMF exposure in brain cells. They also studied how ELF EMF on the brain system. While the mechanisms of the cell that play a role are not fully comprehended however, there is an obvious 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 known methods for regenerating myelin in the brain.
Researchers have observed that exposure to 900 MHz EMF caused a rise in the permeability of BBB and increased signs of neuronal damage in rodents. They also observed an increase in the extravasation of albumin into neurons. Further, they found in 30 minutes exposure to 900 MHz 99mTc-MIBI accelerated its permeation into the brain. But this effect didn't occur with Evans blue injections.
Despite these findings, RF EMF has no clear mechanism to disrupt the BBB. Research suggests that EMF exposure may increase erythrocyte cell membrane permeability, which may influence the BBB and also increase the efflux of calcium-ion. Moreover, the presence of a 99mTc-MIBI radiotracer in the brain is also linked to increased permeability and permeability of the BBB.
