Health Effects of EMF Radiation
RF-EMF radiation can cause damaged DNA, heat to the tissues and disrupt the blood-brain barrier. These effects are real and ARPANSA is active in collaborating with the EHS group, the medical professionals and researchers. The agency will continue review research on the health effects of EMF radiation.
RF-EMF damages DNA
exposed to electromagnetic fields that are created by man (EMFs) are associated with DNA damage, as well as other health adverse effects. EMFs can disrupt the intracellular ionic concentrations that are essential to ensure the balance of electrochemical activity in cells. This can disrupt cell homeostasis, resulting damages to the DNA. Moreover, exposure to EMFs is also linked to an overproduction of free radicals and reactive oxygen species (ROS).
The exposure to radiation from RF-EMF has been associated with changes in male germ cells' development. This is due to the development of germ cells into spermatozoa as well functioning maturation when the spermatozoa move across the epididymis. To study the effects of RF-EMF on male germ cell development, a specifically-designed waveguide machine was constructed to expose unrestrained mice to RF-EME at 2.2 W/kg.
In a recent study, researchers found that exposure to RF-EME caused oxidative DNA damage in 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 recognized as a true carcinogen. However, emf radiation have shown that RF-EMF exposure can impair DNA health in range of cell lines. In one of these studies researchers were exposed Vero cells to an EMF at 100 Hz over about 45 minutes. what is emf radiation evaluated DNA damage 48 hours after exposure to determine whether the exposure affected the integrity of DNA.
The effect of RF-EMF on tissue heating
Although the effects of RF EMF are typically believed to be thermal, a few studies have demonstrated that non-thermal effects are also present. These factors could be responsible for certain of the unsolved findings in epidemiological studies on EMF hypersensitivity. Therefore, it is important to take into account non-thermal effects when conducting a systematic review.
Non-thermal effects from RF-EMF could occur at the cell membrane. This is a field where research has been extensively investigated. Particularly the electrochemical properties of cell membranes has been investigated. Find more info is that energy generated by RF-EMF greater than 1 MHz is transferred to the tissue via dielectric and ionic dissipation. Previous theoretical analyses indicated that the energy that is transferred to tissues could be as high as 200 kV/m.
The electric properties of tissue are controlled by the composition and distribution of water molecules, ions, and other molecules in the body. This determines how absorbent RF EMR is by different tissues. Organs with greater conductivity are likely to absorb more of the EMR field and produce more of an effect. This is the reason why the amount of tissue heating doesn't increase continuously from outside to inside and is only noticeable in hot areas. Bone and fatty tissue are less susceptible to RF heating than other tissues, because they are not as water-based. content.
The intensity of the field's electromagnetic energy depends on the strength and frequency of the field. Muscle tissue absorbs more field 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 higher the frequency, the more shallow 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 the impacts that EMF affect brain function are linked to neurodegenerative diseases. For example, EMF from mobile phones could affect the electroencephalogram's activity and sleep patterns, and the activities of nitric oxide and xanthin oxidase.
Researchers from the Vienna University have studied the effects of RF-EMF exposure in brain cells. They also studied what effects ELF EMFs on the nervous system. While the mechanisms of the cell that are involved aren't fully comprehended, there is a clear connection between exposure to ELF-EMF and myelin depletion. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. However, there are known methods to regenerate myelin within the brain.
Researchers have found that exposure to frequencies of 900 Mhz EMF increased 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. Furthermore, they discovered the following: after about 30 min of exposure to 900 MHz 99mTcMIBI increased its penetration into the brain. However this effect didn't occur when using Evans blue injections.
However, RF-EMF does not have a clear method for disrupting the BBB. The evidence suggests that nonthermal EMF exposure increases erythrocyte membrane permeability, which may affect the BBB and enhance the efflux of calcium ions. Additionally, the presence of a 99mTc-MIBI radiotracer within the brain has been associated with increased permeability of BBB.
