Health and fitness Effects of EMF Radiation
The radiation RF-EMF causes DNA damage, tissue heating, and can disrupt the blood-brain-barrier. These effects are real and ARPANSA is actively involved with the EHS communities, medical specialists and researchers. ARPANSA will continue to study research related to 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 health adverse effects. EMFs can disrupt the intracellular ionic concentrations that are essential to ensure a cell's electrochemical balance. In turn, this can disrupt cell homeostasis, resulting damages to the DNA. Moreover exposure to EMFs can also trigger an increase in the production of free radicals and reactive oxygen species (ROS).

Proteck'd Emf Clothing to radiation from RF-EMF has been linked with alterations in male germ cells' development. This is due to the development of germ cells into spermatozoa as well maturation of the functional aspect as spermatozoa move through the epididymis. To study the effect of RF-EMF exposure on male germ cells A specially designed waveguide machine was designed for the exposure of unrestrained mice to RF EME at 2.2 W/kg.

In a study that was conducted recently, researchers have discovered exposure to RF-EME causes oxidative DNA damage in spermatozoa. Sperm DNA fragmentation increased by 18% after 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).

However, RF-EMF radiation is not yet considered to be a carcinogen. But, numerous studies have shown that RF-EMF exposure can impair the integrity of DNA in variety of cell lines. In one study researchers subjected Vero cell lines to EMF at 100 Hz over 45 minutes. They measured DNA damage 48 hours after exposure to determine if 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 considered to have thermal origins, a few studies have revealed that non-thermal effects are also present. These effects may account for some of the unsolved issues in the epidemiological study of EMF hypersensitivity. This is why it is crucial to look at the non-thermal aspects when conducting an exhaustive review.

Non-thermal effects from RF-EMF may occur on the cell's membrane. This is an area where research has been thoroughly examined. Particularly the electrochemical properties of cell membranes is being studied. It is believed that RF-EMF energy higher than 1 MHz gets transferred to the tissue via dielectric dissipation and ionic discharge. The theoretical studies have indicated that the energy transferred to the tissue could be as high as 200 kV/m.

The electric properties of tissue are regulated through the distribution and composition of water molecules and other molecules within the body. This determines how well absorbed EMR RF is by various tissues. Organs with greater conductivity are likely to absorb more EMR field and produce more of an impact. This is why the level of heating in tissues is not constant between the outside and inside however, it is more prevalent in hot spots. Bone and fatty tissues are less prone to RF heating than other tissues, because they have a low water content.

The depth of the field's electromagnetic energy is determined by the frequency and strength of field. Muscle tissue absorbs more energy than other tissues, and converts it into heat more efficiently. Typically, the depth of penetration for RF EMF is determined in millimeters (mm). The greater the frequency, the more shallow the penetration.


RF-EMF causes blood-brain barrier disruption
Researchers have discovered that RF-EMF can disrupt the blood-brain barrier which can alter sleep patterns and neurotransmitter levels. In addition to this, the effects of EMF in brain activities are associated with neurodegenerative disorders. For example, EMF from mobile phones can alter electroencephalogram activity as well as sleep patterns, in addition to the activities of nitric oxide and xanthin oxide.

Researchers at Vienna University have studied the effects of exposure to RF EMF in brain cells. They also studied how ELF EMF on the brain system. Although the cellular mechanisms involved are not completely comprehended, 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, proven methods for regenerating myelin in the brain.

Researchers have discovered that exposure to frequencies of 900 Mhz EMF enhanced the permeability of the BBB and caused an increase in the signs of neuronal injury in rats. They also observed increased extravasation of neuronal albumin. Further, they found that after 30 minutes of 900 MHz exposure 99mTc-MIBI accelerated its penetration to the cerebral cortex. But this effect didn't occur when using Evans blue-based injections.

Despite these findings, RF EMF does not have a clear mechanism for disrupting the BBB. Research suggests that EMF exposure increases erythrocyte membrane permeability, which could influence the BBB and also increase the efflux of calcium ions. Additionally, the presence of a 99mTc-MIBI radiotracer in the brain has also been associated with an increase in the permeability and permeability of the BBB.
