Wellness Effects of EMF Radiation
The radiation RF-EMF causes damaged DNA, heat to the tissues, and even disrupt the blood-brain barrier. These are real-world effects, and ARPANSA is actively involved with the EHS communities, medical experts, and researchers. The agency will continue review research on the health effects of EMF radiation.

DNA damage is caused by RF-EMF
Exposure to man-made electromagnetic fields (EMFs) can cause DNA damage and other adverse health adverse effects. EMFs can affect intracellular ionic concentrations, which are essential to ensure the balance of electrochemical activity in cells. This can alter the balance of cell metabolism, resulting to DNA damage. Furthermore exposure to EMFs is also associated with an increase in the production of free radicals as well as reactive oxygen species (ROS).

Exposure to RF-EMF radiation has been linked with alterations in male germ cells' development. This is due to the differentiation of the germ cell into spermatozoa as well functioning maturation when the spermatozoa move through the epididymis. To study the sensitivity of RF-EMF exposure to the development of male germ cells, a specially-built waveguide machine was designed for the exposure of unrestrained mice to RF EME with a dose of 2.2 W/kg.

In a recent study, researchers found that exposure to RF-EME triggered an oxidative DNA damage to the spermatozoa. more info increased by 18% after an entire week of treatment and by 23 percent 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 the fact that RF-EMF radiation isn't yet recognized as a true carcinogen. But, numerous studies have found that exposure to RF-EMF radiation can damage DNA integrity in a range of cell lines. In one of these studies researchers exposed Vero cell lines to EMF at 100 Hz over about 45 minutes. They measured DNA damage at 48 hours following exposure to determine if the exposure had a negative effect on DNA integrity.

RF-EMF causes tissue heating
Although the effects of RF-EMF are usually believed as thermal in nature, a few studies have demonstrated that non-thermal effects may also be evident. These factors could be responsible for some of the unresolved observations in epidemiological studies of EMF hypersensitivity. This is why it is crucial to consider the non-thermal effects when conducting systematic reviews.

The non-thermal effects of RF-EMF could occur on the cell's membrane. This is a field where research has been thoroughly examined. Particularly the electrochemical behavior of cell membranes has been investigated. It is believed that energy generated by RF-EMF greater than 1 MHz is transferred to the tissue via dielectric and ionic dissipation. 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 in the body. This determines how absorbent RF EMR is by different tissues. Tissues with higher conductivity tend to absorb more field and cause more of an impact. This is the reason the degree of heating in tissues doesn't increase continuously as it moves from the exterior to however, it is more prevalent in hot spots. Bone and fatty tissue are less susceptible to RF heating than other tissues, because they are not as water-based. content.

The depth of the field's electromagnetic energy depends on the frequency and strength of the field. Muscle tissue is more able to absorb field energy than other tissues and transforms it into heat more efficiently. Usually the depth of penetration of RF-EMF is measured in millimeters (mm). However, the higher the frequency, 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. Additionally the impacts on the effects of EMF on brain activity are associated with neurodegenerative disorders. For instance, EMF from mobile phones can alter electroencephalogram activity as well as sleep patterns, and the activities of nitric oxide and xanthin oxidase.

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 nervous system. Although the cellular mechanisms involved are not completely comprehended but there is a clear relationship between exposure to ELF EMF and myelin depletion. 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 observed that exposure to frequencies of 900 Mhz EMF enhanced the permeability of the BBB and increased symptoms of neuronal damage in rodents. They also observed increased extravasation of neuronal albumin. Further, they found that after 30 minutes of exposure to 900 MHz 99mTc-MIBI accelerated its permeation in the cortex. But this effect didn't occur with Evans blue injections.

However, RF-EMF has no clear mechanism for disrupting the BBB. The evidence suggests that nonthermal EMF exposure can increase erythrocyte membrane permeability. This could affect the BBB and increase calcium ion efflux. Furthermore, the presence a 99mTc-MIBI radiotracer in the brain has also been connected to increasing the permeability of the BBB.
