Most studies have suggested that microwave radiation can cause EEG abnormalities in experimental animals and participants, but some negative results have also been reported in studies using low-power microwaves. 2012;112:1715. Does MW radiation affect gene expression, apoptotic level, and cell cycle progression of human sh-sy5y neuroblastoma cells? Their answers to questionnaires showed that the workers suffered from symptoms including headaches, fatigue, stress and sleeplessness. Thus, the committee suggested that in the future, studies should explore the border between thermal and non-thermal effects and that specific effects, such as triggering the onset of thermoregulatory reactions, should be defined.

This study concerns the effects of microwave on health because they pervade diverse fields of our lives. Dasdag et al. Some studies have proposed that miRNAs play important roles in nerve regeneration, neurodegenerative diseases, and the pathogenesis of neuroblastoma and schizophrenia [93,94,95].

Adverse health effects of occupational exposure to radiofrequency radiation in airport surveillance radar operators. Microwave radiation can heat body tissue the same way it heats your food. [85] found that protein levels were reduced in rat brains following microwave radiation, which may have been caused by the excessive consumption or a reduction of the synthesis of proteins, and reduced protein synthesis can be caused by the following processes: (1) excessive activation of RNA enzymes; (2) mRNA consumption or the formation and maturation of RNA enzymes. Microwave exposure impairs synaptic plasticity in the rat hippocampus and pc12 cells through over-activation of the nmda receptor signaling pathway. However, these effects were not observed in radial arm maze tests. Cassel et al. Of these, five rats were repeatedly exposed to extremely low-frequency microwaves (915MHz; pulse width, 20ms; average power density, 0.3mW/cm2; repetition frequency, 4.0Hz; intermittently for 1min, On for 1min, and Off for 10min; SAR, 0.7mW/g) and 5 were in the sham group. [62] irradiated Wistar rats, hippocampal synaptosomes and differentiated PC12 cells using microwaves (average power density, 30mW/cm2) for 5min, and the results showed that the post-exposure spatial memory of the rats was significantly decreased, the post-exposure levels of phosphorylated synapsin I (p-synapsin I) and GABA were decreased in the rat and cell experiments, and the post-exposure levels of vesicular GABA transporter and p-synapsin I were increased in small clear synaptic vesicles (which were abnormally assembled in presynaptic terminals) in the rat experiments. 2016;74:99107. They found that escape times were substantially decreased when the animals were trained while exposed to the phone. Numerous studies have shown that increased acetylcholine is related to promotion of the effect of glucose on memory [112,113,114]. frequency range from 1GHz to 10^6 GHz.

RF energy has the ability to heat human tissue, much like the way that microwave ovens heat food, and can be hazardous if the exposure is sufficiently intense or prolonged. An increase in anxiety-related behaviors and a decrease in depression-related behavior were observed in both female and male offspring. Campisi A, Gulino M, Acquaviva R, Bellia P, Raciti G, Grasso R, et al. Brain electrical activity originates from the membrane potential of the neuron itself and the fluctuation in membrane potential. Microwave radiation can cause tissue damage by inducing localized microstructural damage to proteins [86, 87]. This classical method is often used to test learning and memory abilities after exposure to microwave radiation. Verma et al.

After exposure to microwave radiation, during synaptic structural plasticity, presynaptic vesicles accumulate or empty, mitochondria are damaged, postsynaptic membranes are perforated, postsynaptic lengths and postsynaptic density distributions are abnormal, mossy fiber growth is inhibited during learning and memory functions, dendritic filopodial densities and activities are decreased, and there is a significant reduction of the dendritic spine density and dendritic fragment length [62]. Repeated Wi-Fi studies show that Wi-Fi causes oxidative stress, sperm/testicular damage, neuropsychiatric effects including EEG changes, apoptosis, cellular DNA damage, endocrine changes, and calcium overload.

The authors therefore proposed that synaptic conduction disorders are associated with damage to cognitive functions. Mikrobiolohichny zhurnal (Kiev, Ukraine: 1993) Serge Voychuk. Mol Neurobiol. The above results indicate a positive biological effect of microwave radiation and present a challenge with regard to how people can benefit from microwave radiation. Human SH-SY5YNB cells were exposed to 2.1GHz W-CDMA modulated microwave radiation for 24h at a specific absorption rate of 0.491W/kg. In summary, there is evidence that microwave radiation can lead to alterations in protein synthesis or protein modifications; however, the results are controversial. Cordless phone radiation effect flows in a human body same way in the mobile phone [13]. The interaction of microwaves with matter other than metallic conductors will be to rotate molecules and produce heat as result of that molecular motion. Those who are accustomed to using their mobile phone ipsilaterally presented a probability that was twice that of people who dont [5,6,7]. In long-term epidemiological investigations of large population with occupational exposure, the results have not been consistent. Schz J, Jacobsen R, Olsen JH, Boice JD, McLaughlin JK, Johansen C.

The microwave will do its intended job of heating and will start to burn (or cook) the skin tissue. The three groups were further divided into two groups according to their years of service (up to 10years and >10years) to investigate the effect of years of exposure to radar. A large number of studies have shown that microwave radiation can cause a series of adverse reactions in the central nervous system, including sleep disorders in addition to learning and memory impairments. In the probe test, the exposed group could not locate the platform and exhibited a significantly higher mean latency (i.e., 3-fold higher) to reach the target quadrant, and they spent only half the time that the controls spent in the target quadrant. Kumar M, Singh SP, Chaturvedi CM. fMicrowave Radiation Comes From Many Sources, Including: Cell phones. Furthermore, the expression of postsynaptic density 95 (PSD-95) in cultured neurons was decreased. 2004;996:8996. Additionally, people exposed to military microwave sources were more vulnerable to brain tumors. The results indicated that radar microwave radiation leads to a decreased reaction time and lower short-term memory performance [18]. The conclusions are shown in Table3.
