The radiation RF-EMF causes damages to DNA and tissue, and disrupt the blood-brain barrier. These effects are real, and ARPANSA is actively engaged with the EHS communities, medical experts as well as researchers. ARPANSA will continue to examine research regarding the health effects caused by EMF radiation.
RF-EMF damages DNA
exposed to electromagnetic fields that are created by man (EMFs) is associated with DNA damage as well as health consequences. EMFs can disrupt the intracellular ionic concentrations that are crucial to maintain the electrochemical balance of cells. This can alter the balance of cell metabolism, resulting to DNA damage. Furthermore exposure to EMFs is also associated with an overproduction of free radicals as well as reactive oxygen species (ROS).
Exposure to RF-EMF radiation has been linked with alterations in the male germ cell's development. This results in the development of germ cells into spermatozoa, aswell maturation of the functional aspect as spermatozoa pass across the epididymis. To determine the effects of RF-EMF on male germ cell development A specially designed waveguide machine was designed to expose non-restrained mice to RF-EMF at 2.2 W/kg.
In a study that was conducted recently, researchers have discovered that exposure to RF-EME triggered oxidative DNA damage in spermatozoa. Sperm DNA fragmentation increased by 18% following a 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).
Despite this, RF-EMF radiation is not yet considered to be a carcinogen. However, numerous studies have revealed that exposure to RF-EMF can affect DNA integrity in a range of cell varieties. In one such study researchers subjected Vero cells with an EMF of 100 Hz for 45 minutes. They assessed DNA damage for within 48 hours of exposure to determine if exposure affected the integrity of DNA.
The effect of RF-EMF on tissue heating
Although the effects of RF-EMF are generally thought to be thermal, some studies have revealed that non-thermal effects may also be present. These may be the reason for some of the unsolved issues in epidemiological studies of EMF hypersensitivity. It is therefore important to consider the non-thermal effects when conducting systematic reviews.
The non-thermal effects of RF-EMF may occur on the cell's membrane. This is a field which has already been thoroughly examined. Particularly, the electrochemical behavior of cell membranes has been investigated. Current understanding suggests that energy generated by RF-EMF greater than 1 MHz is transferred into the tissues through dielectric dissipation and ionic discharge. Studies of the theory have suggested that the energy transferred to tissues could be as high as 200 kV/m.
The electric properties of tissues are regulated by the composition and distribution of water molecules, ions and other molecules inside the body. Visit this link determines how absorbed EMR from RF is absorbed by different tissues. Tissues with higher conductivity tend to absorb more of the field, and thus cause more of an effect. This is the reason why the amount of heating in tissues doesn't increase continuously between the outside and inside and is only noticeable in hot areas. Bone and fatty tissues are less susceptible to heating by RF as compared to other tissues, since they have a low water content.
The extent of the field's electromagnetic energy is determined by the frequency and strength of the field. Muscle tissue absorbs more field energy than other tissues and converts it into heat more efficiently. Usually the penetration depth that RFEMF has is measured in millimeters (mm). But, the greater the frequency, the shallower the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have discovered that RF-EMF can disrupt the blood-brain barrier, altering sleep patterns and neurotransmitter levels. Additionally to this, the effects that EMF on brain activity are linked to neurodegenerative diseases. For example, EMF from mobile phones could affect the electroencephalogram's activity and sleep patterns, and the activity of nitric oxide and xanthin oxidase.
emf radiation symptoms at Vienna University have studied the effects of exposure to RF-EMF in brain cells. They also examined the effects of ELF EMF on brain system. While the mechanisms of the cell aren't completely known however, there is an obvious connection between exposure to ELF-EMF and depletion of myelin. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. However, there are known methods to regenerate myelin in the brain.
Researchers have observed that exposure to the frequency of 900 millimeters EMF enhanced the permeability of BBB and increased signs of neuronal damage in rats. emf radiation observed an increase in the release of albumin into neurons. Additionally, they observed in 30 minutes exposure to 900 MHz 99mTcMIBI increased its penetration into the brain. But this effect didn't occur when using Evans blue-based injections.
Despite these findings, RF-EMF is not able to provide a definitive mechanism for disrupting the BBB. The evidence suggests that nonthermal EMF exposure can increase erythrocyte membrane permeability. This could alter the BBB and also increase the efflux of calcium ions. Furthermore, the presence a 99mTcMIBI radiotracer inside the brain is also connected to increasing the permeability and permeability of the BBB.
