Wifi base station radiation

Chronic exposure to these radiations produced formation of apoptotic cells in testis. In addition, a significant decrease in the levels of antioxidant enzymes glutathione and superoxide dismutase activities as well as an increase in catalase activity was observed in the exposed group.

These results indicate that a low level exposure of microwave radiations exerts a negative impact on male reproductive system function. Maganioti, A. The present study investigated the influence of 2. The presence of radiation had no effect on the energies of alpha and beta band of male subjects, while it reduced these energies of female subjects, resulting in significantly lower energies, as compared to those of males.

Delta and theta band energies did not experience any noteworthy effect from gender, radiation condition and their interaction. Conversely, there was a significant interaction effect gender x radiation on the energies of alpha and beta rhythms. The present data support the idea that Wi-Fi signal may influence normal physiology through changes in gender related cortical excitability, as reflected by alpha and beta EEG frequencies.

Gumral, N. This study measured the levels of blood lipid peroxidation, glutathione peroxidase, reduced glutathione, and vitamin C to follow the level of oxidative damage caused by 2.

The possible protective effects of selenium and L-carnitine were also tested and compared to untreated controls. Researchers found that 2. L-carnitine seems to have protective effects on the 2. EMR-exposed animals showed lower concentration of vitamins A, C, and E than controls, although their concentrations were increased by selenium and L-carnitine supplementation.

Animals which received selenium and L-carnitine in addition to EMR also showed lower levels of lipid peroxidation. Results indicate that L-carnitine and selenium seem to have protective effects on the 2. Sinha, R. The purpose of this investigation was to analyze the effects of chronic 2. Behavioral changes were found to be significantly changed from controls for immobilization, rearing and ambulation behavior. Changes in behavioral parameters are also correlated with the trend of changes, compared to control animals, in hormonal blood levels of T3 and T4.

Researchers concluded that low energy microwave irradiation may be harmful as it is sufficient to alter the levels of thyroid hormones as well as the emotional reactivity of the irradiated compared to control animals. Paulra,j R. This investigation concerns with the effect of low intensity microwave 2.

Paulraj R. This experiment investigated the effects of 2. Electron microscopic study shows an increase in the glial cell population in the exposed group as compared to the control group. This present study is indicative of a significant change after exposure to the above-mentioned field intensity, which suggests that chronic exposures may affect brain growth and development.

Chou, C. This study investigated the effects of long-term exposure to 2. The major emphasis was to expose a large sample of experimental animals throughout their lifetimes Results showed negative overall effects of RFR on general health, longevity, cause of death, or lesions associated with aging and benign neoplasia.

Positive findings of effects were found on corticosterone levels and immune system. A statistically significant increase in primary malignancies in exposed rats vs. Somosy, Z. Mouse embryo 3T3 cells were irradiated with MHz continuous and low frequency 16 Hz square modulated waves of absorbed energy.

The low frequency modulated microwave irradiation yielded more morphological cell changes than did the continuous microwave fields of the same intensity. The amount of free negative charges cationized ferritin binding on cell surfaces decreased following irradiation by modulated waves but remained unchanged under the effect of a continuous field of the same dose.

Modulated waves of 0. Similar effects were experienced by continuous waves at higher 0. Engineering Science and Technology, an International Journal, This paper presents a methodology to determine the threshold distance at which the field strength levels from the AP are negligible in comparison with the radiation generated by a user equipment.

The theoretical concepts, which can be applied to other technologies, were implemented by means of simulations and experimental measurements.

For the simulations, actual WiFi antennas were modelled. Experimental measurements completed the results obtained in simulations, resulting in a greater number of real situations.

Results showed that the threshold distance depends on the WiFi standard employed by the devices connected to the network.

This distances can increase in multipath environments as demonstrated in Section 5. In all the cases, if the UE was placed closer to the human body, the threshold distance would be lower.

This conclusion may lead to a misconcep-tion that needs to be clarified. The results point out that the higher the UE power is, the lower threshold distance to the AP is allowed.

However, regarding safety as the main scope of this type of research, such threshold situations characterized by maximum power UEs and minimum distances to APs should be avoided by all means. That is, the higher the threshold distance is, the better the exposure scenario will be. Experimental results showed that the threshold distance depends on the bandwidth employed by the communication link,which is related to the WiFi standard employed by the AP and UE.

Furthermore, measurements in the whole 5 GHz WiFi band were carried out in a university environment and it was proved that WiFi signals coming from further APs have lower influence than at 2. Finally, the threshold distances were also calculated in multipath environments.

The proposed methodology ensures that WiFi APs will not be a matter of concern if the user is located at larger distances than the threshold distance. On the contrary, measurements of the radiation coming from the hotspot would be needed at shorter distances, in order to check the compliance with the reference levels.

Finally, the duration of signal transmission may be of great interest when assessing EMF exposure, especially in places where people spend many hours such as schools, universities or offices. In this regard, WiFi exposure levels at 2.

As can be observed inFig. But even during working hours, WiFi activity and therefore AP and UE transmissions varies from one location to another inside the same building. Research on animals Bas et al. There is human data consistent with these animal studies, as they have found higher cell phone radiation associated with behavioral problems and memory damage Thomas et al , Divan et al. These animal studies in combination with the human and cell studies should spur immediate action to minimize exposure.

RFR cannot be given a clean bill of health. Compendium of Research studies on Wi-Fi and 2. Children are more vulnerable to radiofrequency wireless radiation Proportionately deeper penetration of RFR into the brain: Children have smaller heads than adults with shorter distances from their skull to the brain center, resulting in higher RFR absorption extending deeper into the brain compared to an adult Morris et al.

Thinner skulls and higher conductivity of tissues allow higher intensities of RFR into the eye and brain: Scientific modeling finds younger brains absorb proportionally more radiation in the eyes and brain—grey matter, cerebellum and hippocampus Fernandez et al. More active stem cells in their bodies: Research shows that stem cells are more sensitive to microwave radiation, and children have more active stem cells Belyaev , Williams et al.

Developing brains are more vulnerable to neurotoxic exposures: Not only do children absorb higher peak doses in the brain than adults, their brain is growing rapidly, subject to different windows of vulnerability, and thus more susceptible to adverse impacts and environmental neurotoxicants.

Exposures that take place during fetal development or early childhood may cause permanent brain injury, whereas the same doses may have little impact in adults Heindel et al.

A lifetime of exposure : Children will receive a greater cumulative exposure than adults Belpomme et. Brain Damage from Wireless Research on animals Bas et al. Action Needed A Yale study funded by the American Cancer Society found that cell phone use was significantly associated with thyroid cancer in people with genetic susceptibilities Luo Replicated studies on prenatal and postnatal exposures have found associations with behavioural problems in young children Divan A study by the National Institutes of Health on humans found increased glucose metabolism in the brain region closest to the transmitting cell phone antenna Volkow A study published in the Public Library of Science found that children with higher blood lead levels, who made more voice calls on their cell phone, were at significantly greater risk of developing ADHD symptoms Byun et al.

A study examined mother-child pairs. A study found people living closer to cell antennas had higher RFR exposure and had statistically significant higher frequency of micronuclei and greater lipid peroxidation in their blood. Frequently Asked Questions. The radiation range of the base station is generally based on the base station power setting. In the urban area, there are many users, which is more important than signal quality. Generally, the power is small and there are many base stations.

The coverage area is m in the suburban area. There are few users, which is more important than signal coverage. Larger, fewer base stations, and a coverage radius of about 10 kilometers. Radiation is only related to the working frequency, transmitting frequency, and receiving frequency of the equipment. Does 5G base station signal radiation affect the human body?

At present, the signal radiation of 5G base stations is still within the controllable range and does not have much impact on the human body. According to the explanation by the person in charge of the Shenzhen Monitoring Center, in our daily life, there is a lot of radiation, which is mainly divided into two types: ionizing radiation and non-ionizing radiation.

Non-ionizing radiation generally refers to radio waves. The energy of this radiation is very low and is not enough to destroy the chemical bonds of substances in the organism. It is safe. What the 5G base station uses is radio waves, that is, non-ionizing radiation. This kind of radio waves, like broadcasting and wireless TV, have no effect on the human body and cause no harm.
