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.
The advent of Wi-Fi connected high technology devices in executing day-to-day activities is fast evolving especially in developing countries of the world and hence the need to assess its safety among others. The present study was conducted to investigate the injurious effect of radiofrequency emissions from installed Wi-Fi devices in brains of young male rats. Animals were divided into four equal groups; group 1 served as control while groups 2, 3, and 4 were exposed to 2.5 Ghz at intervals of 30, 45, and 60 consecutive days with free access to food and water ad libitum. Alterations in harvested brain tissues were confirmed by histopathological analyses which showed vascular congestion and DNA damage in the brain was assayed using agarose gel electrophoresis. Histomorphometry analyses of their brain tissues showed perivascular congestion and tissue damage as well.
RESULTS: Data obtained from the One day test showed an increase in concentration of blood glucose, decrease in Triglyceride level and GGT factor (P<0.05), however no observed significant difference on the Cholesterol, HDL, LDL level and hepatic enzymes activities in compare to control group. Groups of the five-day test showed reduction in the amount of blood glucose, elevation of cholesterol level and LDL relative to control group (P<0.05).
Most smartphones have settings that will help you manage your privacy and safety. You can find these controls through the settings on your phone or through the settings of a specific app. These settings may allow you to limit an application’s access to the data on your phone, including access to your location, pictures, contacts, notes, etc. You may even be able to block cookies and limit what data your mobile browser collects.
Performance is good, delivered by the Snapdragon 450, though it might struggle a little bit with multitasking. We found swapping between demanding apps caused the phone to slow down a bit — but it also handled simple games fairly well, and provided solid enough performance most of the time. There are plenty of storage options too, with 32GB available as a base option, and the ability to add a MicroSD card for extra room.
People who say cell phones are safe reference statements by the FCC and Food and Drug Administration (FDA) and point to peer-reviewed studies which conclude that cell phone use is not associated with an increased risk of brain tumors or the onset of other health problems. They contend there has been no increase in brain tumor rates despite hundreds of millions of people now using cell phones.
To date, there are a few long-term studies, very few in humans and even fewer epidemiological studies, apart from the studies on laptops with small numbers of study subjects. It is also far too early to generate reliable figures at this time. However, there are indications that especially newborns, children, or adolescents are particularly vulnerable as has been presented in detail by the research teams of Nazırogˇ lu, Atasoy, Margaritis/ Panagopoulos, Orendacˇ ova, Othmann, Ozorak, Sangun, Shahin and Yuksel. The experiments were carried out with rats or mice, in some cases as long-term studies (up to 1 year). In this context, it is important to note that rats and mice used in laboratories have a life expectancy of perhaps two years. This at least allows us to infer that human children and adolescents have to be protected from possible increased risks. In the study of Margaritis et al. (2014), the authors point out that the exposure levels from Bluetooth (0.3 V/m) and Wi-Fi routers (here 2.1 V/m) showed greater effects than cell phone radiation sources with much higher field strengths. This may coincide with the findings of the papers by von Klitzing, which stated that the power-dependent pulse of 10 Hz (1 ms) from Wi-Fi routers triggered reactions. Kumari et al. observed in a study from 2012 that higher levels of ROS in the liver suppress antioxidant enzymes and that lower levels cause an increase. This could be a key to further mechanisms as to how or whether tissue damage occurs or perhaps not. Likewise, the polarization of RF radiation (Meena et al. 2014, Panagopoulos et al. 2015) should also receive additional attention.
In September 2014, Californian oncologists reported four similar case histories of young women who had developed breast cancer in precisely the areas where they normally carried their smartphones. What shocked the doctors was that these women were aged 21 to 39 and had no family history or other risk factors relating to cancer. All their cancers “had striking similarity, all tumours were hormone positive… (with) an extensive intraductal component and… near-identical morphology.” (CaseRepMed., 2013).
