The radiation from RF-EMF can cause damaged DNA, heat to the tissues and disrupt the blood-brain barrier. These effects are real and ARPANSA is actively engaged within the EHS communities, medical professionals as well as researchers. The agency will continue study research related to the health effects of EMF radiation.
RF-EMF damages DNA
The exposure to electromagnetic fields created by humans (EMFs) are associated with DNA damage, as well as other negative health consequences. EMFs can alter the intracellular ionic concentrations that are crucial to maintain the electrochemical balance of cells. It can also disrupt cell homeostasis, resulting damages to the DNA. Furthermore, exposure to EMFs is also linked to the production of free radicals and reactive oxygen species (ROS).
The exposure to radiation from RF-EMF has been linked with alterations in male germ cell development. This involves the transformation of germ cells into spermatozoa as well functioning maturation when the spermatozoa pass through the epididymis. To determine the effects of RF-EMF on male germ cells A specially designed waveguide device was developed to expose unrestrained mice to RF-EMF with a dose of 2.2 W/kg.
In a study that was conducted recently, researchers discovered exposure to RF-EME causes an oxidative DNA damage to spermatozoa. Sperm DNA fragmentation increased by 18% following an entire 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).
Despite this the fact that RF-EMF radiation isn't yet considered a carcinogen. But, numerous studies have shown that exposure to RF-EMF radiation can damage DNA integrity in a variety of cell varieties. In one of these studies, scientists were exposed Vero cells to an EMF of 100 Hz for 45 minutes. They measured DNA damage 48 hours after exposure to determine whether the exposure affected DNA integrity.
RF-EMF causes tissue heating
Although the effects of RF EMF are generally considered as thermal in nature, a few studies have demonstrated that non-thermal influences are also evident. These factors could be responsible for some of the unsolved issues in the epidemiological study of EMF hypersensitivity. It is therefore important to look at the non-thermal aspects when conducting a systematic review.
The non-thermal effects of the RF-EMF can occur on the cell's membrane. This is an area where research has been extensively investigated. In particular the electrochemical behavior of cell membranes has been studied. The current understanding is that RF-EMF energy higher than 1 MHz is transferred to the tissue via dielectric and ionic dissipation. Studies of the theory have suggested that the energy transferred to the tissue 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 in the body. This determines how absorbed EMR from RF is absorbed by different tissues. Tissues with higher conductivity tend to absorb more EMR field and produce more of an effect. This is the reason why the amount of heat generated by tissue doesn't increase continuously between the outside and inside the body and is only noticeable in hot areas. Bone and fatty tissue is less susceptible to heating by RF than other tissues, because they are low in water content.
emf radiation of penetration of the electromagnetic field is determined by the strength and frequency of field. Muscle tissue absorbs more field radiation than most tissues, and converts it to heat more efficiently. Typically the penetration depth for RF EMF is determined in millimeters (mm). emf radiation , the deeper the penetration.
RF-EMF causes blood-brain barrier disruption
Researchers have discovered that RF-EMF can disrupt the blood-brain barrier changing sleep patterns as well as neurotransmitter levels. In addition, the effects that EMF in brain activities are associated with neurodegenerative disorders. For example, EMF from mobile phones can alter electroencephalogram activity as well as sleep patterns, and the activities of nitric oxide and xanthin oxide.
Researchers at the Vienna University have studied the effects of exposure to RF-EMF on brain cells. They also studied the effects of ELF EMF on the brain system. While the mechanisms of the cell involved are not completely understood, there is a clear connection between exposure to ELF-EMF and depletion of myelin. This relationship might account for the electro-hypersensitivity symptoms of electro-hypersensitivity. Fortunately, there are some tested methods to regenerate myelin in the brain.
Researchers have found that exposure to 900 Mhz EMF caused a rise in the permeability of BBB and caused an increase in signs of neuronal damage in rodents. is emf radiation harmful observed an increase in the release of albumin to neurons. Further, they found that after 30 minutes of exposure to 900 MHz 99mTcMIBI increased its diffusion to the cerebral cortex. However this effect didn't occur when using Evans blue injections.
Despite these findings, RF EMF has no clear method for disrupting the BBB. The evidence suggests that nonthermal EMF exposure may increase erythrocyte cell membrane permeability. This could alter the BBB and increase the efflux of calcium ions. Furthermore, the presence a 99mTcMIBI radiotracer inside the brain has been connected to increasing the permeability of BBB.
