effect of microwave on human body ppt

[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. Effect of a 915-MHz simulated mobile phone signal on cognitive function in man. 1 Microwave radiation may also lead to skin cancer/health problems when we are within the radius of a cell phone tower in a certain specified limited distance.

Privacy Standard devices used by military personnel that may pose electromagnetic hazards include radars and missile systems. [27] found that college students visual reaction times were significantly shorter after 10min of phone-induced microwave radiation. pability of the body (thus, a thermal effect), whereas the standard of the U.S.S.R. and Poland are based upon the interaction of the microwave fields with the brain and central nervous system as measured by neurological or behavior effects. 2014;8:63. This study concerns the effects of microwave on health because they pervade diverse fields of our lives. Repeated exposure to low-level extremely low frequency-modulated microwaves affects cortex-hypothalamus interplay in freely moving rats: EEG study. The results demonstrated the ability of electric magnetic field (EMF) to influence plasma melatonin and serotonin concentrations in radar workers. The direct cause of the observed neuronal damage may have been apoptosis induced by the microwave radiation, and an indirect cause may have been an increase in permeability of the blood-brain barrier (BBB), which would allow the traversal of toxic substances that could cause damage. The microwave energy can be changed to warm up the food because this energy is absorbed by food & it does not prepare food contaminated or radioactive. Ning W, Chiang H, Yang W.

Frequency Fields (RF) and Microwave Radiation on human health" by the Scientific Committee on Toxicity, Ecotoxicity and the Environment (CSTEE) from 2001, with respect . Wang et al. 2005;130:591600. One reason for this difference may be that the water maze experiment is driven by aversion, whereas the arm maze experiment is driven by appetite. 2006;27:295306. It has been proposed that by enhancing the functions of acetylcholine, glucose can increase the concentration of free calcium ions in the synapse to reverse microwave-induced damage to learning and memory. Trends Cell Biol. Glucose is the main energy source and is closely related to brain neurotransmitters and cholesterol synthesis [106]. Vorobyov et al. Szmigielski [23] collected retrospective data for Polish soldiers over 15years and showed that the prevalence of brain cancer was higher in each age group. Chronic exposure to GSM 1800-MHz microwaves reduces excitatory synaptic activity in cultured hippocampal neurons. 2010;86:37683. Bioelectromagnetics. B. Cordless phones effect Cordless phone same worked like a mobile phone. Motawi TK, Darwish HA, Moustafa YM, Labib MM. A large amount of heat can be generated to caused severe damage to the body. [58] exposed volunteers to microwaves at a frequency of 450MHz for 10 repeated intervals of 1min of irradiation and 1min off. In the rat hippocampus, glucose uptake plays an important role in spatial learning and memory processes. Cordless phone in power levels very high and microwave frequency level also high. This phenomenon may be explained by the varied radiation dosage adopted in these studies. Impairment of long-term potentiation induction is essential for the disruption of spatial memory after microwave exposure. 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. It addresses the impact on developing head and brain tumours, other morbidity-related outcomes and summarizes the biological effects of RF and microwave radiation.

Mol Neurobiol. Therefore, in this article, we reviewed recent studies that have explored the effects of microwave radiation on the brain, especially the hippocampus, including analyses of epidemiology, morphology, electroencephalograms, learning and memory abilities and the mechanisms underlying brain dysfunction. The effects of hyperthermia and hyperthermia plus microwaves on rat brain energy metabolism. Correspondence to However, impaired learning and memory were only observed in males. Chizhenkova R.

Neurotransmitter systems involved in learning and memory in the rat: a meta-analysis based on studies of four behavioral tasks. More than 50% of miRNAs are found in cancer-associated regions of the genome or in fragile sites, suggesting that miRNAs also play important roles in the pathogenesis of neoplasias [96]. [40] also repeated the experiment only and found that radial-arm maze performance in rats remained unchanged. [80] found that irradiation with 900MHz, 2W/kg continuous microwaves for 24h induced an increase in rat neuronal apoptosis. 2006;98:170713. 1996;93:46938. Eur J Nucl Med Mol Imaging. 1984;5:6370. The rats in the study showed increases in spatial memory and glucose transporters, and this phenomenon indicated a corresponding increase in glucose uptake. Thus, in the early developmental stage, chronic exposure to 2.4W/kg GSM microwaves may influence dendritic development and the formation of excitatory synapses in cultures of hippocampal neurons. Springer Nature. 2014;90:2935. Electromagnetic radiation can be absorbed by organisms, in which it causes a series of physiological and functional changes. Neurol Sci. 2014:125. Neuroreport. Moreover, the popularization of mobile phones has made them the main source of brain exposure to radiation. Rev Environ Health. Wang et al. 1988;9:33745. Additionally, the number of crossings was significantly lower at 3 d after microwave radiation. In a report by the Poland Department of Microwave Safety, occupational exposure to electromagnetic fields was analyzed in the work environment of personnel of 204 devices divided into 5 groups (surface-to-air missile system radars, aircraft and helicopters, communication devices, surveillance and height finder radars, airport radars and radio navigation systems). In summary, there is evidence that microwave radiation can lead to alterations in protein synthesis or protein modifications; however, the results are controversial. A radio frequency electric current enhances antibiotic efficacy against bacterial biofilms. Larjavaara S, Schz J, Swerdlow A, Feychting M, Johansen C, Lagorio S, et al.

Apoptosis gene expression and their relationship to mtDNA mutation in tumor tissues of gynecologic oncology patients. However, a recent report [3] published by the Scientific Committee on Emerging and Newly Identified Health Risks (SCENIHR) noted that discussions about the thermal and non-thermal effects are misleading. Most bioassay and genotoxicity or mutation studies that have been performed in vitro have reported that exposure to microwave radiation at non-thermal levels does not have mutagenic/genotoxic/carcinogenic effects. After exposure, the levels of 2 waves in the hypothalamus increased more than those in the cortex, leading to a significant reduction in the deviation of the two EGGs. Maternal exposure to Wi-Fi radio frequencies led to various adverse neurological effects in the offspring. Int J Epidemiol. Toxicol Sci. Resulting Effects on the Human Body. As a result, the existing data exhibit poor reproducibility and comparability. J Natl Cancer Inst.
