Health and fitness Effects of EMF Radiation The radiation RF-EMF causes damages to DNA and tissue and even disrupt the blood-brain barrier. These effects are real and ARPANSA is active in collaborating in discussions with EHS communities, medical specialists and researchers. ARPANSA will continue to examine research regarding the health effects of EMF radiation.


DNA damage is caused by RF-EMF
exposed to electromagnetic fields that are created by man (EMFs) is associated with DNA damage, as well as other health effects. EMFs can disrupt the intracellular ionic concentrations that are essential to ensure the electrochemical balance of cells. emf radiation can cause disruption to cell homeostasis and result damages to the DNA. Furthermore, exposure to EMFs is also linked to the production of free radicals as well as reactive oxygen species (ROS).

The exposure to radiation from RF-EMF has been linked with alterations in male germ cell development. This results in the differentiation of the germ cell into spermatozoa, aswell maturation of the functional aspect as spermatozoa move throughout the epididymis. To investigate the effect of RF-EMF exposure on male germ cells, a specifically-designed waveguide device was developed to expose non-restrained mice to RF EME at 2.2 W/kg.

In a recent study, researchers discovered exposure to RF-EME causes an oxidative DNA damage to spermatozoa. Sperm DNA fragmentation increased by 18% after one 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).

However it isn''t yet considered to be a carcinogen. But, numerous studies have shown that exposure to RF-EMF can affect the integrity of DNA in range of cell varieties. In one study, scientists subjected Vero cell lines to EMF that was 100Hz, for 45 minutes. They measured DNA damage within 48 hours of exposure to determine whether the exposure affected DNA integrity.

The RF-EMF effect causes the heating of tissues
Although the effects of RF-EMF are usually believed as thermal in nature, some 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 look at the non-thermal aspects when conducting an exhaustive review.

Non-thermal effects from RF-EMF could occur on the cell''s membrane. This is an area where research has been extensively examined. Particularly the electrochemical properties of cell membranes has been investigated. It is believed that RF-EMF energy higher than 1 MHz is transferred into the tissues through dielectric dissipation and ionic discharge. Previous theoretical analyses indicated that the energy transfer to tissues could be up to 200 kV/m.

The electric properties of tissues are controlled in the form and quantity of water molecules and ions and other molecules inside the body. This determines how well absorbed EMR from RF is absorbed by different tissues. Tissues with higher conductivity tend to absorb more field and cause more of an effect. This is the reason why the amount of tissue heating doesn''t increase continuously as it moves from the exterior to, but occurs in hot areas. Bone and fatty tissue is less prone to RF heating as compared to other tissues, since they are not as water-based. content.

The intensity 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 converts it into heat more efficiently. Typically the penetration depth of RF-EMF is measured as millimeters (mm). But, the greater the frequency, the deeper the penetration.

RF-EMF causes blood-brain barrier disruption
Researchers have found that RF EMF can alter the blood-brain-barrier which can alter sleep patterns and neurotransmitter levels. Furthermore to this, the effects on the effects of EMF on brain activity have been linked to neurodegenerative disorders. For instance, EMF from mobile phones could affect the electroencephalogram''s activity and sleep patterns, as well as the activity of nitric oxide and xanthin oxidase.

Researchers at the Vienna University have studied the effects of exposure to RF-EMF in brain cells. They also examined how ELF EMF on the nervous system. While the mechanisms of the cell involved are not completely comprehended, there is a clear relationship between exposure to ELF EMF and depletion of myelin. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. However, there are proven methods for regenerating myelin in the brain.

Researchers have discovered that exposure to 900 MHz EMF enhanced the permeability of the BBB and caused an increase in symptoms of neuronal damage in rodents. They also observed an increase in the extravasation of albumin to neurons. Additionally, they observed in 30 minutes exposure at 900 MHz, 99mTc-MIBI increased its permeation in the cortex. However, this effect did not occur when using Evans blue injections.

However, RF-EMF has no clear method for disrupting the BBB. Research suggests that EMF exposure can increase erythrocyte membrane permeability. This could influence the BBB and enhance the efflux of calcium-ion. Furthermore, the presence a 99mTcMIBI radiotracer inside the brain is also associated with an increase in the permeability of the BBB.
