Well being Effects of EMF Radiation
The radiation from RF-EMF can cause DNA damage, tissue heating and can disrupt the blood-brain-barrier. These are real-world effects, and ARPANSA is actively engaged in discussions with EHS group, the medical professionals, and researchers. The agency will continue review research on the health effects caused by EMF radiation.

DNA damage is caused by RF-EMF
The exposure to electromagnetic fields created by humans (EMFs) is associated with DNA damage and other adverse health adverse effects. EMFs can alter 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 damages to the DNA. Moreover, exposure to EMFs is also associated with an increase in the production of free radicals and reactive oxygen species (ROS).

The exposure to radiation from RF-EMF has been linked to changes in the male germ cell's development. This involves the transformation of germ cells into spermatozoa, as well as functional maturation as the spermatozoa move throughout the epididymis. To study the sensitivity of RF-EMF exposure to male germ cells A specially designed waveguide device was developed for the exposure of unrestrained mice to RF-EMF at 2.2 W/kg.


In a recent study, researchers have discovered that exposure to RF-EME caused an oxidative DNA damage to 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).

Despite this, RF-EMF radiation is not yet considered to be a carcinogen. However, numerous studies have revealed that exposure to RF-EMF radiation can damage DNA integrity in a variety of cell lines. In one such study, scientists exposed Vero cell lines to EMF of 100 Hz for about 45 minutes. They measured DNA damage within 48 hours of exposure to determine whether the exposure had a negative effect on DNA integrity.

The RF-EMF effect causes the heating of tissues
Although the effects of RF-EMF are usually believed to have thermal origins, some studies have shown that non-thermal effects are also present. These may be the reason for some of the unsolved issues in epidemiological studies on EMF hypersensitivity. Therefore, it is important to consider the non-thermal effects when conducting a systematic review.

Non-thermal effects from RF-EMF may be mediated by the cell membrane. This is an area which has already been extensively examined. Particularly the electrochemical properties of cell membranes has been studied. It is believed that RF-EMF energy higher than 1 MHz is transmitted to the tissue via dielectric and ionic dissipation. The theoretical studies have indicated that the energy transfer to the tissue could be as high as 200 kV/m.

The electrical properties of tissues are regulated by the composition and distribution of water molecules, ions, and other molecules within the body. This determines how absorbent EMR RF is by various tissues. Organs with greater conductivity are likely to absorb more of the field and cause more of an impact. This is the reason why the amount of tissue heating does not increase steadily as it moves from the exterior to the body, but occurs in hot spots. Bone and fatty tissue are less prone to RF heating as compared to other tissues, since they are low in water content.

The intensity of the field's penetration is determined by the frequency and strength that the electromagnetic field has. Muscle tissue absorbs more field energies than the other tissue, and transforms it into heat more effectively. Typically, the depth of penetration for RF EMF is determined by millimeters (mm). But, the higher the frequency, the more shallow the penetration.

RF-EMF causes blood-brain barrier disruption
Researchers have found that RF EMF can alter the blood-brain-barrier which can alter sleep patterns and neurotransmitter levels. In addition the impacts on the effects of EMF affect brain function are linked to neurodegenerative disorders. For instance, EMF from mobile phones can alter electroencephalogram activity as well as sleep patterns, as well as the actions of nitric Oxide and xanthin oxidase.

Researchers from the Vienna University have studied the effects of RF-EMF exposure to brain cells. emf radiation symptoms examined how ELF EMF on brain system. Though the cellular mechanisms aren't completely understood but there is a clear association between ELF-EMF exposure and myelin depletion. 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 increased the permeability of the BBB and raised signs of neuronal damage in rodents. They also observed increased extravasation of neuronal albumin. Additionally, they observed in 30 minutes exposure to 900 MHz 99mTcMIBI increased its diffusion to the cerebral cortex. However, this effect did not occur with Evans blue injections.

However, RF-EMF does not have a clear mechanism for disrupting the BBB. Research suggests that EMF exposure can increase erythrocyte membrane permeability, which could influence the BBB and enhance calcium ion efflux. Moreover, the presence of a 99mTc-MIBI radiotracer within the brain has been associated with increasing the permeability and permeability of the BBB.
