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.
A few years ago, the science regarding links between cell phone radiation and various health ailments was a very emergent science. Even today, most scientists disagree about many of the findings. However, the fact that so many new studies are discovering effects that cell phone radiation can have on human biology, it makes sense to play it safe. If there are no negative health effects, then you're only out a few bucks. But if it turns out there really are serious health issues related to cell phone radiation, then by protecting yourself early, you can protect your health and potentially save your life by getting a cell phone anti-radiation shield.
Moving the meter around the case, we detect readings on the side, back and front of the case. We use the multi-directional TES 593 meter which measures 10 MHz to 8GHz. We use the unit of micro-watts per square centimeter, which looks like this little symbol: μW/cm² and we use it on the max setting which shows the maximum measured value. In non-science speak: the highest level of RF we see, which could be from the back the side or the front.
These days it takes more than simply ringing the steel triangle on your deck to round up the kids for supper. Technology has advanced, and the need for a more efficient way to maintain contact with children from afar has only increased, bolstered by their growing thirst for independence and reliance on consumer technology. Despite the fact that cell phones have become the obvious solution for basic communication and contact in lieu of the landline — and to a lesser degree, the steel triangle — they still pose both a financial and safety risk.
The purpose of this study was to investigate the oxidative damage and protective effect of garlic (daily 500 mg/kg during study period) on rats exposed to low level of electromagnetic fields (EMF) at 2.45 GHz Microwave radiation (MWR) for 1 h/day for 30 consecutive days. Researchers concluded that low level EMF at 2.45 GHz MWR increases the DNA damage in both brain tissues and plasma of the rats whereas it increases protein oxidation only in plasma. They also be argued that the use of garlic decreases these effects.
38. Does your child need that phone feature? Parental control apps allow parents to exert greater control over the features and functions their children can access on their smartphones. Making use of these apps and other tools to restrict access to the features you deem safe and appropriate can go a long way in keeping your kids safe while giving you much-needed peace of mind. “Determine what features your child needs based on his age. Does your 10-year-old really need web browsing capabilities?” – Laura Willard, Cell Phone Safety Tips for Kids, Tweens and Teens, SheKnows; Twitter: @SheKnows
The king is dead — long live the king. If you’re looking for a smartphone that doesn’t break the bank and won’t sting too much if it’s lost, but still offers good performance, then Motorola’s G-range is usually where you’d start. This year, the Moto G6 has upped the ante, delivering a glass-and-metal design that your sprog won’t be ashamed to be seen with. A protective case is included in the package, but you might want to pick from our range of the best Moto G6 cases, since glass is prone to breaking.
Members of the public often ask about the cumulative exposure that a child receives when using a Wi-Fi device in a classroom in which a number of children are simultaneously using Wi-Fi. When downloading files, most of the transmissions will be from the access point, not the students’ device. When downloading and uploading only a portion of the maximum capacity of a network would be used even in a classroom filled with children using Wi-Fi. The Wi-Fi network divides RF transmissions among the access points and client devices therefore the individual RF exposure to a child in a classroom that is using a device consists of sequential exposures from all active devices, the majority of which are located at some distance away(15). For the majority of schools (20) the measurements in the current study were conducted in an empty classroom (to avoid lesson disruption) with an access point and one laptop. In three schools, measurements were conducted with students or teachers present and using Wi-Fi devices. A comparison between measurements conducted in empty classrooms and classrooms with multiple students/teachers using Wi-Fi showed no significant difference in the RF levels (p > 0.1 for all); although this may have been due to low numbers (only three schools measured with multiple users in the classroom).
Since the development of communication devices and expansion of their applications, there have been concerns about their harmful health effects. The main aim of this study was to investigate laptop thermal effects caused by exposure to electromagnetic fields and thermal sources simultaneously; propose a nondestructive, replicable process that is less expensive than clinical measurements; and to study the effects of positioning any new device near the human body in steady state conditions to ensure safety by U.S. and European standard thresholds. A computer simulation was designed to obtain laptop heat flux from SolidWorks flow simulation. Increase in body temperature due to heat flux was calculated, and antenna radiation was calculated using Computer Simulation Technology (CST) Microwave Studio software. Steady state temperature and specific absorption rate (SAR) distribution in user's body, and heat flux beneath the laptop, were obtained from simulations. The laptop in its high performance mode caused 420 (W/m2 ) peak two-dimensional heat flux beneath it. The cumulative effect of laptop in high performance mode and 1 W antenna radiation resulted in temperatures of 42.9, 38.1, and 37.2 °C in lap skin, scrotum, and testis, that is, 5.6, 2.1, and 1.4 °C increase in temperature, respectively. Also, 1 W antenna radiation caused 0.37 × 10-3 and 0.13 × 10-1.
This study investigated the long-term effects of low-level 2.45GHz MW irradiation (2h/day for 30 days) on the reproductive function of male mice and its mechanism of action. Researchers observed that MW irradiation induced a significant decrease in sperm count and sperm viability along with the decrease in seminiferous tubule diameter, degeneration of seminiferous tubules, reduction in testicular 3β HSD activity and reduction in plasma testosterone levels. Increased expression of testicular i-NOS was observed in the MW-irradiated group of mice. These adverse reproductive effects suggest that chronic exposure to nonionizing MW radiation may lead to infertility via free radical species-mediated pathway.
The most compelling evidence though comes from a Swedish team of cancer experts whose research stretches back 15 years. The results clearly demonstrate “a consistent association between long-term use of cell phone and cordless phones and glioma and acoustic neuroma”. Overall, they found that using a cell phone for more than a decade significantly increases the risk of a malignant tumour by almost two times with an analogue cell phone and by nearly four times with a digital phone. Interestingly, the risks were even higher for people who had started using mobiles as teenagers.
