Health and fitness Effects of EMF Radiation
RF-EMF radiation can cause damage to DNA, increase the temperature of tissues and alter the blood brain barrier. These effects are real and ARPANSA is actively engaged in discussions with EHS communities, medical experts, and researchers. The agency will continue to review research on the health effects caused by EMF radiation.
RF-EMF causes DNA damage
The exposure to electromagnetic fields created by humans (EMFs) are associated with DNA damage as well as health adverse effects. EMFs can affect the intracellular ionic levels that are vital to maintain the balance of electrochemical activity in cells. It can also alter the balance of cell metabolism, resulting to DNA destruction. Additionally, exposure to EMFs can also trigger the production of free radicals and reactive oxygen species (ROS).
The exposure to radiation from RF-EMF has been associated with changes in male germ cell development. This involves the transformation of germ cells into spermatozoa, aswell functional maturation when the spermatozoa pass across the epididymis. To investigate the effect of RF-EMF exposure on male germ cells, a specifically-designed waveguide machine was constructed to expose unrestrained mice to RF-EME at 2.2 W/kg.
In a study that was conducted recently, researchers found that exposure to RF-EME causes oxidative DNA damage in spermatozoa. Sperm DNA fragmentation increased by 18% after one 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).
Although the radiation emitted by RF-EMF isn't yet considered to be a carcinogen. However, several studies have found that exposure to RF-EMF can affect DNA health in variety of cell lines. In one such study, scientists subjected Vero cells with an EMF that was 100Hz, for about 45 minutes. They assessed DNA damage for at 48 hours following exposure to determine if exposure affected the integrity of DNA.
The effect of RF-EMF on tissue heating
While the effects of RF EMF are typically considered to have thermal origins, a few studies have demonstrated that non-thermal influences are also evident. These factors could be responsible for some of the unresolved issues in epidemiological studies of EMF hypersensitivity. It is therefore important to take into account non-thermal effects when conducting an exhaustive review.
The non-thermal effects that RF-EMF can have may be mediated by the cell membrane. This is a field of research that has been extensively investigated. Particularly the electrochemical properties of cell membranes has been studied. The current understanding is that RF-EMF energy that exceeds 1 MHz is transferred to the tissue through dielectric as well as ionic dissipation. Previous theoretical analyses indicated that the energy that is transferred to tissues 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 substances in the body. This determines how absorbent RF EMR is by different tissues. Organs with greater conductivity are likely to absorb more of the field, and thus cause more of an impact. what is emf radiation is the reason why the amount of heat generated by tissue doesn't increase continuously from outside to inside, but occurs in hot areas. Bone and fatty tissue is less prone to RF heating than other tissues because they are not as water-based. content.

Muscle tissue absorbs more energy than other tissues and converts it to heat more efficiently. Usually the depth of penetration for RF EMF is determined by millimeters (mm). But, the greater the frequency, the deeper the penetration.
RF-EMF causes emf radiation -brain barrier disruption
Researchers have discovered that RF EMF can disrupt the blood-brain barrier change sleep patterns as well as neurotransmitter levels. In addition to this, the effects of EMF affect brain function have been linked to neurodegenerative disorders. For instance, EMF from mobile phones can affect electroencephalogram activity and sleep patterns, and the actions of nitric Oxide and xanthin oxidase.
Researchers at the Vienna University have studied the effects of RF-EMF exposure to brain cells. They also looked at how ELF EMF on the brain system. Although the cellular mechanisms involved are not completely understood 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, proven methods for regenerating myelin in the brain.
Researchers have discovered that exposure to the frequency of 900 millimeters EMF enhanced the permeability of BBB and also increased the signs of neuronal damage in rodents. They also observed increased exovasation of albumin into neurons. Further, they found in 30 minutes 900 MHz exposure 99mTc-MIBI accelerated its permeation into the brain. However this effect did not occur when using Evans blue injections.
However, RF-EMF does not have a clear mechanism to disrupt the BBB. The evidence suggests that nonthermal EMF exposure increases erythrocyte membrane permeability. This could alter the BBB and also increase the efflux of calcium-ion. Moreover, the presence of a 99mTc-MIBI radiotracer in the brain is also connected to increasing the permeability and permeability of the BBB.
