Non-ionizing radiation at 2.45 GHz may modify the morphology and expression of genes that codify heat shock proteins (HSP) in the thyroid gland. The present study used a diathermy model – the therapeutic application of non-ionizing radiation – on laboratory rats subjected to maximum exposure non-ionizing radiation (30 min, 10 times in two weeks) in the left front leg, in order to study the effects of radiation on the nearby thyroid tissue.Ninety minutes after radiation with the highest SAR, the central and peripheral follicles presented increased size and the thickness of the peripheral septa had decreased. Twenty-four hours after radiation, only peripheral follicles radiated at 12 W were found to be smaller. Morphological changes in the thyroid tissue may indicate a glandular response to acute or repeated stress from radiation in the hypothalamic-pituitary-thyroid axis.
Thirty-two rats and their forty newborn offspring were divided into the following four groups according to the type of EMR exposure they were subjected to: the control, 900, 1800, and 2450 MHz groups. Each experimental group was exposed to EMR for 60 min/day during the pregnancy and growth periods. The pregnant rats were allowed to stand for four generations (total 52 weeks) before, plasma and uterine samples were obtained. During the 4th, 5th, and 6th weeks of the experiment, plasma and uterine samples were also obtained from the developing rats. [The electric field density was set at 20 dB and 11 V/m in order to obtain 0.1 W/kg whole-body average specific absorption rate (SAR).]
This study investigated the effects of mobile phone (900 and 1800 MHz)- and Wi-Fi (2450 MHz)-induced electromagnetic radiation (EMR) exposure (60 min/day during pregnancy and growth periods) on uterine oxidative stress and plasma hormone levels in pregnant rats and their offspring. Although EMR exposure decreased the prolactin, estrogen, and progesterone levels in the plasma of maternal rats and their offspring, EMR-induced oxidative stress in the uteri of maternal rats increased during the development of offspring. Mobile phone- and Wi-Fi-induced EMR may be one cause of increased oxidative uterine injury in growing rats and decreased hormone levels in maternal rats.
In 2015, the European Commission Scientific Committee on Emerging and Newly Identified Health Risks concluded that, overall, the epidemiologic studies on cell phone radiofrequency electromagnetic radiation exposure do not show an increased risk of brain tumors or of other cancers of the head and neck region (2). The Committee also stated that epidemiologic studies do not indicate increased risk for other malignant diseases, including childhood cancer (2).
I used to keep my Bsnl wifi modem close to my bed and I saw lots of negative impact of it.I cannot sleep in time since I started using anroid phone and wifi. It’s very difficult for me to wake up early in the morning in time.I have become lazy and dull nowadays.I am not able to concentrate in anything properly.I cannot remember things.I forget to do many things .I feel that my brain has become very much inactive. I don’t feel like doing any works like in the past I was very active in doing my official works and other home works.two months back I came to know that I have a diabetic as well.give me some suggestion to live a healthy life and to make my brain more active .
30. There isn’t one cell phone that is safer than another. “Don’t assume one cell phone is safer than another. There’s no such thing as a “safe” cell phone. This is particularly true for industry promoted SAR ratings, which are virtually useless in measuring the true potential biological danger as most all of the damage is not done by heat transfer, which SAR measures.” – Dr. Mercola, NEW Urgent Warning to All Cell Phone Users, Mercola.com; Twitter: @mercola
In February of 2008, a research study was published in the American Journal of Epidemiology. The study, conducted at Tel Aviv University, examined 500 Israelis who had developed salivary gland cancer and compared their level of mobile phone usage to 1,300 healthy adults. The researchers discovered that within the entire group, those who used their cell phone for a few hours a day had 50 percent higher odds of developing a salivary gland tumor.
This study investigated the effect of 2GHz EMR (1h) on the growth dynamics of Myriophyllum aquaticum (Parrot feather) by measuring the nanometric elongation rate fluctuation (NERF) using a statistical interferometry technique. After continuous exposure to EMR, M. aquaticum plants exhibited a statistically significant reduction in NERF standard deviation, therefore, the reduced NERF was due to a non-thermal effect caused by EMR exposure. The alteration in NERF continued for at least 2.5 h after EMR exposure and no significant recovery was found in post-EMR NERF during the experimental period.
This paper presents the results of a replication study performed to investigate earlier Soviet studies conducted between 1974 and 1991 that showed immunological and reproductive effects of long-term low-level exposure of rats to radiofrequency electromagnetic fields (continuous wave 2450 MHz for 7h/day, 5days/week for 30 days). The RF exposure resulted in minor increases in formation of antibodies in brain tissue extract and the exposure did not appear to be pathological. In addition, a study was conducted to replicate a previous Soviet study on effects from the injection of blood serum from RF-exposed rats on pregnancy and foetal and offspring development of rats, using a similar animal model and protocol. Our results showed the same general trends as the earlier study, suggesting possible adverse effects of the blood serum from exposed rats on pregnancy and foetal development of intact rats, however, application of these results in developing exposure standards is limited.
This study examined the possible ability of 2.45 GHz microwave radiation exposure (30 min) to modify the expression of genes that codify heat shock proteins (HSP) in the thyroid gland. Ninety minutes after radiation, HSP-90 and HSP-70 had decreased significantly (P<0.01); Twenty-four hours after radiation, HSP-90 had partially recovered and HSP-70 had recovered completely. There were few indications of lesions in the glandular structure and signs of apoptosis were negative in all radiated animals. The results suggest that acute sub-thermal radiation at 2.45 GHz may alter levels of cellular stress in rat thyroid gland without initially altering their anti-apoptotic capacity.
In 2011, the World Health Organization classified radio frequency radiation of the type used by WiFi devices as a Group 2B possible carcinogen. A study conducted by the University of Vienna have found WiFi exposures to cause genotoxicity as they break single and double strand DNAs in our body. This indicates that there are effects that may potentially surface with our future generations.
This study investigated the effects of 2.45 GHz microwave radiation (exposed once or repeatedly – ten times in two weeks) on the cellular activation within the paraventricular nucleus of the hypothalamus, extracted from rat brains. High SAR triggered an increase of the c-Fos marker 90 min or 24 h after radiation, and low SAR resulted in c-Fos counts higher than in control rats after 24 h. Repeated irradiation at 3 W increased cellular activation of PVN by more than 100% compared to animals subjected to acute irradiation and to repeated non-radiated repeated session control animals. The results suggest that PVN is sensitive to 2.45 GHz microwave radiation at non-thermal SAR levels.
In subsequent analyses of Interphone data, investigators addressed issues of risk according to specific location of the tumor and estimated exposures. One analysis of data from seven of the countries in the Interphone study found no relationship between brain tumor location and regions of the brain that were exposed to the highest level of radiofrequency radiation from cell phones (9). However, another study, using data from five of the countries, reported suggestions of an increased risk of glioma and, to a lesser extent, of meningioma developing in areas of the brain experiencing the highest exposure (10).
I have treated patients with cancer for over thirty years as a board-certified radiation oncologist and I am familiar with every carcinogenic agent known to man. I'll tell you with absolute certainty that radio waves cannot harm you (unless perhaps you were in the path of a multi-megawatt microwave beam, in which case they might cook you. But as far as I know, there is no likelihood that this danger even exists).
TRPV1 cation channels are the possible molecular pathways responsible for changes in the hormone, oxidative stress, and body temperature levels in the uterus of maternal rats following a year-long exposure to electromagnetic radiation exposure from mobile phones and Wi-Fi devices. It is likely that TRPV1-mediated Ca2+ entry in the uterus of pregnant rats involves accumulation of oxidative stress and opening of mitochondrial membrane pores that consequently leads to mitochondrial dysfunction, substantial swelling of the mitochondria with rupture of the outer membrane and release of oxidants such as superoxide (O2 −) and hydrogen peroxide (H2O2). The superoxide radical is converted to H2O2 by superoxide dismutase (SOD) enzyme. Glutathione peroxidase (GSH-Px) is an important antioxidant enzyme for removing lipid hydroperoxides and hydrogen peroxide and it catalyzes the reduction of H2O2 to water.
Carlo sent letters to each of the industry’s chieftains on October 7, 1999, reiterating that the WTR’s research had found the following: “The risk of rare neuro-epithelial tumors on the outside of the brain was more than doubled…in cell phone users”; there was an apparent “correlation between brain tumors occurring on the right side of the head and the use of the phone on the right side of the head”; and “the ability of radiation from a phone’s antenna to cause functional genetic damage [was] definitely positive….”8
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 2.45 GHz electromagnetic radiation exposure (60 min/day for 28 days) in rats. The possible protective effects of selenium and L-carnitine were also tested and compared to untreated controls. Researchers found that 2.45 GHz electromagnetic radiation caused oxidative stress in blood of rat. L-carnitine seems to have protective effects on the 2.45-GHz-induced blood toxicity by inhibiting free radical supporting antioxidant redox system although selenium has no effect on the investigated values.
The most critical concept when it comes to talking about radiation is the distinction between ionizing and non-ionizing radiation. Ionizing radiation is the dangerous stuff and includes x-ray radiation, gamma radiation, and some amount of ultra-violet light on the high end of the ultra-violet spectrum. The key element here is the wavelength of the radiation type.
My son likes to listen to music when he sleeps. He subscribes to Spotify, and has his playlists downloaded to his phone. He now uses airplane mode at night & uses Spotify this way–but of course he sleeps w/ his phone. (He also sleeps in a basement.) Is this still dangerous? If so, what do you suggest he do to be able to listen to continuous music safely at night? He is 21 and resistant to put down the phone… but he does listen, esp. if others (esp non-Mom others!), particularly “professionals” give solid researched reasons. I am going to print this article and share it with him. (My other 3 teenagers don’t have an issue and several don’t even have a phone… but he’s my firstborn, and more into the phone…)
49. Get insurance on your child’s phone. “54% of kids plan on spending their summer playing outside. With so many opportunities for their cellphone to become broken, stolen or misplaced, it’s important to protect their device with mobile protection, considering that nearly 30% of parents have had to replace a child’s cellphone in the past 18 months. This will protect their device against damage (including water damage), loss and theft. Ask your carrier about getting the most comprehensive coverage available for your device.” – 5 Summer Cellphone Safety Tips for Kids, Asurion; Twitter: @Asurion
According to the results of the current research, long-term exposure to EMR emitted from wireless devices had adverse effects on the antioxidant potential of blood. Therefore, to protect individuals from harmful effects of Wi-Fi signals, it is advised to limit the use of such devices for household and occupational activities, if possible. This study may stimulate future helpful research in the development of new protective or therapeutic approaches. In addition, it is recommended that the target tissues of EMR emitted from wireless devices and the level of other mediators be investigated to understand the exact molecular mechanism and site of action upon continuous exposure to such radiations.
This study used Drosophila as model organisms to assess the effects of various EMF sources (short time daily for 3-7 days) on apoptotic cell death of follicles during oogenesis and reproductive capacity (fecundity) decline. Sources included: 900/1800 MHz mobile phone, 1880-1900 MHz wireless base, wireless handset, mobile phone-handset combination, 2.44 GHz wireless network (Wi-Fi), 2.44 GHz bluetooth, 92.8 MHz FM generator, 27.15 MHz baby monitor, 900 MHz CW RF generator and microwave oven’s 2.44 GHz RF and magnetic field components. All EMF sources used created statistically significant effects regarding fecundity and cell death-apoptosis induction, even at very low intensity levels well below ICNIRP’s guidelines, suggesting that Drosophila oogenesis system is suitable to be used as a biomarker for exploring potential EMF bioactivity.
you really are stuck with “electricity”. How much electricity do gamma rays produce in human body yet so damaging to human and animal tissues because of their high level of energy. it seems any discussion with you is a waste of time considering your demonstrably shaky fundamentals of physics. you appear to be a very good technician rather than physicist of any kind.
We did not simply measure energy coming from the front of the case which is the area of the case where the phone would be "shielded" from radiation. If we had taken readings with a directional meter, specifically measuring energy coming from only the front or flap cover where the shielding material is, we assume as the manufacturers claim, that we would have seen a drop in the radiation readings.
But researchers can make some judgments about the potential for harm based on how WiFi and similar technologies work, as well as on how people tend to use their devices. Those factors do provide some reasons to think that WiFi and Bluetooth devices may be less of a concern, says Leeka Kheifets, Ph.D., a professor of epidemiology at the UCLA School of Public Health who has studied the potential health effects of low-level radiation.
