Well being Effects of EMF Radiation
The radiation from RF-EMF can cause damaged DNA, heat to the tissues and can disrupt the blood-brain-barrier. These effects are real, and ARPANSA is actively engaged within the EHS community, medical experts, and researchers. The agency will continue to examine research regarding the health effects of EMF radiation.

RF-EMF damages DNA
Exposure to man-made electromagnetic fields (EMFs) are associated with DNA damage, as well as other adverse health effects. EMFs can disrupt the intracellular ionic levels, which are crucial to maintain a cell's electrochemical balance. In turn, this can cause disruption to cell homeostasis and result damages to the DNA. Furthermore, exposure to EMFs is also linked to an overproduction 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 is due to the transformation of germ cells into spermatozoa, as well functioning maturation when the spermatozoa move across the epididymis. To study the effects of RF-EMF on male germ cell development A specially designed waveguide device was developed to expose unrestrained mice to RF-EMF in the range of 2.2 W/kg.

In a study that was conducted recently, researchers found that exposure to RF-EME triggered the oxidation of DNA in the spermatozoa. Sperm DNA fragmentation was increased by 18% after a 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).


However it isn't yet considered to be a carcinogen. However, numerous studies have found that exposure to RF-EMF can affect DNA health in variety of cell lines. In one of these studies, scientists were exposed Vero cells with an EMF at 100 Hz over about 45 minutes. They assessed DNA damage for within 48 hours of exposure to determine if exposure affected DNA integrity.

The effect of RF-EMF on tissue heating
Although the effects of RF EMF are usually thought as thermal in nature, some studies have revealed that non-thermal effects are also observed. These factors could be responsible 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 systematic reviews.

Non-thermal effects from RF-EMF may occur at the cell membrane. This is an area of research that has been extensively examined. In particular the electrochemical properties of cell membranes has been investigated. Current understanding suggests that RF-EMF energy higher than 1 MHz is transferred to the tissue via dielectric dissipation and ionic discharge. Studies of the theory have suggested that the energy transfer to the tissue could be as high as 200 kV/m.

The electrical properties of tissues are regulated in the form and quantity of water molecules and ions, and other molecules in the body. This determines how absorbent EMR RF is by various tissues. Tissues with higher conductivity tend to absorb more of the EMR field and produce more of an effect. This is the reason why the amount of heating in tissues does not increase steadily as it moves from the exterior to the body however, it is more prevalent in hot spots. Bone and fatty tissue is less susceptible to RF heating than other tissues, because they are not as water-based. content.

The intensity of penetration of the electromagnetic field depends on the frequency and strength of field. Muscle tissue absorbs more energies than the other tissue, and converts it into heat more effectively. Usually Look at this website for RF EMF is determined as millimeters (mm). The greater the frequency, the deeper 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. Furthermore, the effects on the effects of EMF in brain activities are linked to neurodegenerative diseases. For instance, EMF from mobile phones can alter electroencephalogram activity as well as sleep patterns, and the activity of nitric oxide and xanthin oxide.

Researchers at Vienna University have studied the effects of RF-EMF exposure on brain cells. They also studied the effects of ELF EMF on the brain system. Though the cellular mechanisms that are involved aren't fully understood, 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. However, there are tested methods to regenerate myelin inside the brain.

Researchers have found that exposure to 900 MHz EMF caused a rise in the permeability of the BBB and raised the signs of neuronal injury in rodents. They also observed an increase in the extravasation of albumin into neurons. Further, they found the following: after about 30 min of exposure at 900 MHz 99mTcMIBI increased its diffusion into the brain. However, this effect did not occur with Evans blue injections.

However, RF-EMF is not able to provide a definitive mechanism for disrupting the BBB. Research suggests that EMF exposure increases erythrocyte membrane permeability, which could alter the BBB and enhance calcium ion efflux. Additionally, the presence of a 99mTcMIBI radiotracer inside the brain is also connected to increased permeability of the BBB.
