RF-EMF radiation can cause damage to DNA, increase the temperature of tissues and alter the blood-brain barrier. These are real-world effects, and ARPANSA is actively engaged with the EHS communities, medical specialists and researchers. The agency 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 and other health effects. is emf radiation harmful can disrupt the intracellular ionic levels that are vital to maintain the balance of electrochemical activity in cells. This can alter the balance of cell metabolism, resulting in DNA damage. Moreover exposure to EMFs can cause an increase in the production of free radicals and reactive oxygen species (ROS).

Exposure to RF-EMF radiation has been linked to changes in the male germ cell's development. This results in the transformation of germ cells into spermatozoa, aswell functional maturation when the spermatozoa travel across the epididymis. To study the sensitivity of RF-EMF exposure to male germ cells, a specially-built waveguide machine was constructed for the exposure of unrestrained mice to RF-EME at 2.2 W/kg.

In a recent study, researchers have discovered that exposure to RF EME caused the oxidative DNA damage of the spermatozoa. Sperm DNA fragmentation increased by 18% following a week of treatment, and by 23 percent 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, the radiation emitted by RF-EMF isn't yet considered to be a carcinogen. However, emf radiation have found that exposure to RF-EMF can affect the integrity of DNA in variety of cell types. In one study, scientists subjected Vero cells with an EMF at 100 Hz over about 45 minutes. They assessed DNA damage for at 48 hours following exposure to determine whether the exposure affected DNA integrity.


The effect of RF-EMF on tissue heating
Although the effects of RF-EMF are generally believed to have thermal origins, some studies have demonstrated that non-thermal effects may also be observed. These may be the reason for some of the unresolved issues in epidemiological studies of EMF hypersensitivity. Therefore, it is important to take into account non-thermal effects when conducting an extensive review.

The non-thermal effects of RF-EMF could be felt at the cell's membrane. This is an area which has already been extensively investigated. In particular the electrochemical properties of cell membranes has been studied. It is believed that energy from RF-EMFs greater than 1 MHz is transmitted to the tissue through dielectric as well as the dissipation of ions. Previous theoretical analyses indicated that the energy that is transferred to tissues could be as high as 200 kV/m.

The electric properties of tissues are regulated through the distribution and composition of water molecules, and other molecules in the body. This determines how 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 tissue heating does not increase steadily as it moves from the exterior to the body however, it is more prevalent in hot spots. Bone and fatty tissues are less susceptible to RF heating than other tissues because they have a low water content.

The intensity of the field's penetration depends on the strength and frequency of the field. Muscle tissue absorbs more energies than the other tissue, and converts it to heat more efficiently. Typically the penetration depth of RF-EMF is measured as millimeters (mm). But, the higher the frequency, more shallow the penetration.

RF-EMF causes blood-brain barrier disruption
Researchers have discovered that RF-EMF can disrupt the blood-brain barrier change sleep patterns as well as neurotransmitter levels. Additionally the impacts of EMF affect brain function have been associated with neurodegenerative disorders. For instance, EMF from mobile phones can affect electroencephalogram activity and sleep patterns, and the activity of nitric oxide and xanthin oxide.

Researchers at Vienna University have studied the effects of exposure to RF-EMF in brain cells. They also examined the effects of ELF EMFs on the brain system. Though the cellular mechanisms that are involved aren't fully understood however, there is an obvious association between ELF-EMF exposure and myelin depletion. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. Fortunately, there are some proven methods for regenerating myelin inside the brain.

Researchers have observed that exposure to the frequency of 900 MHz EMF enhanced the permeability of the BBB and also increased the signs of neuronal damage in rats. They also observed increased exovasation of neuronal albumin. Additionally, what is emf radiation observed in 30 minutes 900 MHz exposure 99mTcMIBI increased its penetration to the cerebral cortex. However this effect didn't occur with Evans blue-based injections.

Despite these findings, RF EMF has no clear method for disrupting the BBB. The evidence suggests that nonthermal EMF exposure can increase erythrocyte membrane permeability, which may alter the BBB and also increase calcium ion efflux. Moreover, the presence of a 99mTcMIBI radiotracer inside the brain has been connected to an increase in the permeability and permeability of the BBB.
