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 with the EHS group, the medical professionals and researchers. The agency will continue study research related to the health effects of EMF radiation.
RF-EMF causes DNA damage
exposed to electromagnetic fields that are created by man (EMFs) is associated with DNA damage, as well as other negative health consequences. EMFs can disrupt intracellular ionic concentrations, which are crucial to maintain the electrochemical balance of cells. It can also alter the balance of cell metabolism, resulting to DNA damage. Additionally 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 with alterations in male germ cell development. This is due to the development of germ cells into spermatozoa, as well functioning maturation when the spermatozoa move across the epididymis. To determine the effects of RF-EMF on male germ cell development, a specially-built waveguide machine was designed to expose non-restrained mice to RF EME at 2.2 W/kg.
In a study that was conducted recently, researchers found exposure to RF-EME causes the oxidation of DNA in spermatozoa. Sperm DNA fragmentation increased by 18% following an entire week of treatment and by 23 percent 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 recognized as a true carcinogen. However, several studies have found that exposure to RF-EMF can affect DNA health in range of cell types. In one such study researchers exposed Vero cell lines to EMF that was 100Hz, for 45 minutes. They assessed DNA damage for 48 hours after exposure to determine if exposure affected DNA integrity.
The effect of RF-EMF on tissue heating
Although the effects of RF EMF are usually considered to be thermal, a few studies have demonstrated that non-thermal effects are also evident. what is emf radiation may account for some of the unsolved issues in the epidemiological study of EMF hypersensitivity. It is therefore important to consider the non-thermal effects when conducting an exhaustive review.
The non-thermal effects of RF-EMF may occur on the cell's membrane. what is emf radiation is a field which has already been thoroughly studied. In particular the electrochemical behavior of cell membranes has been investigated. Current understanding suggests that energy from RF-EMF higher than 1 MHz gets transferred to the tissue via dielectric and ionic dissipation. Studies of the theory have suggested that the energy transfer to tissues could be as high as 200 kV/m.
The electrical properties of tissues are controlled by the composition and distribution of water molecules, ions and other molecules inside the body. This determines how well absorbed EMR RF is by various tissues. The tissues with the highest conductivity tend to absorb more EMR field and produce more of an effect. This is the reason the degree of heat generated by tissue doesn't increase continuously as it moves from the exterior to however, it is more prevalent in hot spots. Bone and fatty tissues are less susceptible to RF heating than other tissues, because they are low in water content.
The extent of the field's electromagnetic energy depends on the strength and frequency of field. Muscle tissue absorbs more energies than the other tissue, and transforms it into heat more efficiently. Typically, the depth of penetration of RF-EMF is measured by millimeters (mm). But, the higher the frequency, shallower the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have found that RF-EMF can disrupt the blood-brain barrier which can alter sleep patterns and neurotransmitter levels. Additionally the impacts on the effects of EMF affect brain function have been linked to neurodegenerative disorders. For what is emf radiation , 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 at the Vienna University have studied the effects of exposure to RF EMF on brain cells. They also examined the effects of ELF EMFs on the brain system. Although the cellular mechanisms involved are not completely known but there is a clear association between ELF-EMF exposure and depletion of myelin. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. There are, however, known methods to regenerate myelin within the brain.
Researchers have found that exposure to the frequency of 900 millimeters EMF caused a rise in the permeability of the BBB and caused an increase in signs of neuronal damage in rodents. They also observed an increase in the release of neuronal albumin. Additionally, they observed the following: after about 30 min of exposure to 900 MHz 99mTc-MIBI accelerated its diffusion in the cortex. But, this effect did not occur with Evans blue injections.
Despite these findings, RF-EMF is not able to provide a definitive method for disrupting the BBB. The evidence suggests that nonthermal EMF exposure can increase erythrocyte membrane permeability, which may affect the BBB and enhance calcium ion efflux. Moreover, the presence of a 99mTc-MIBI radiotracer in the brain has been connected to increased permeability and permeability of the BBB.
