Health and fitness Effects of EMF Radiation
The radiation from RF-EMF can cause DNA damage, tissue heating, and disrupt the blood-brain barrier. These effects are real, and ARPANSA is active in collaborating with the EHS group, the medical specialists and researchers. The agency will continue to review research on the health effects caused by EMF radiation.

DNA damage is caused by RF-EMF
exposed to electromagnetic fields that are created by man (EMFs) is associated with DNA damage and other negative health consequences. EMFs can disrupt the intracellular ionic concentrations that are crucial to maintain a cell's electrochemical balance. This can cause disruption to cell homeostasis and result in DNA damage. Moreover exposure to EMFs is also associated with 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 to changes in the male germ cell's development. This is due to the development of germ cells into spermatozoa, as well maturation of the functional aspect as spermatozoa move throughout the epididymis. To investigate the effects of RF-EMF on male germ cells A specially designed waveguide machine was designed for the exposure of unrestrained mice to RF EME in the range of 2.2 W/kg.

In a study that was conducted recently, researchers discovered that exposure to RF-EME triggered the oxidation of DNA in spermatozoa. Sperm DNA fragmentation was increased by 18% after an entire 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. But, numerous studies have revealed that exposure to RF-EMF can affect DNA health in range of cell varieties. In one of these studies, scientists exposed Vero cell lines to EMF of 100 Hz for about 45 minutes. They evaluated DNA damage at 48 hours following exposure to determine if the exposure affected DNA integrity.

RF-EMF causes tissue heating
While the effects of RF-EMF are generally thought to be thermal, a few studies have demonstrated that non-thermal effects are also observed. emf sickness may be the reason for certain of the unsolved findings in epidemiological studies on EMF hypersensitivity. Therefore, it is important to consider the non-thermal effects when conducting systematic reviews.

Non-thermal effects from the RF-EMF can be mediated by the cell membrane. This is a field where research has been extensively studied. Particularly the electrochemical behavior of cell membranes has been studied. The current understanding is that energy generated by RF-EMF greater than 1 MHz is transmitted to the tissue via dielectric dissipation and ionic discharge. Studies of the theory have suggested that the energy transferred to the tissue could be as high as 200 kV/m.

The electric properties of tissue are controlled in the form and quantity of water molecules and 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 EMR field and produce more of an effect. This is why the level of heating in tissues does not increase steadily between the outside and inside, but occurs in hot areas. Bone and fatty tissue is less susceptible to RF heating than other tissues because they have a low water content.

The extent of penetration of the electromagnetic field is determined by the strength and frequency that the electromagnetic field has. Muscle tissue absorbs more energy than other tissues and transforms it into heat more efficiently. Typically the depth of penetration for RF EMF is determined by millimeters (mm). However, 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 changing sleep patterns as well as neurotransmitter levels. In addition, the effects that EMF in brain activities are associated with neurodegenerative disorders. For instance, EMF from mobile phones can affect electroencephalogram activity and sleep patterns, as well as the activities of nitric oxide and xanthin oxide.

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

Researchers have found that exposure to frequencies of 900 MHz EMF enhanced the permeability of BBB and increased the signs of neuronal injury in rats. They also observed increased extravasation of albumin into neurons. Additionally, they observed the following: after about 30 min of 900 MHz exposure 99mTc-MIBI accelerated its diffusion to the cerebral cortex. However, this effect did not occur with Evans blue-based injections.

Despite these findings, RF-EMF is not able to provide a definitive method for disrupting the BBB. Research suggests that EMF exposure can increase erythrocyte membrane permeability, which could influence the BBB and enhance the efflux of calcium-ion. Moreover, the presence of a 99mTc-MIBI radiotracer in the brain has been associated with increasing the permeability of BBB.
