With that in mind, several school districts in the U.S. and other countries have tried to reduce exposure in the classroom to RF radiation from devices. The Maryland State Department of Education, for example, recommended in 2016 that school districts use wired networks instead of WiFi whenever possible, turn off routers when not being used, and keep routers as far away from students as possible. In France, WiFi is banned from nursery schools.
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
Users of wireless devices are typically exposed for much longer periods than for mobile phones and the strength of wireless devices is not significantly less. Whereas a Universal Mobile Telecommunications System (UMTS) mobile phone can range from 21 dBm (125 mW) for Power Class 4 to 33 dBm (2W) for Power class 1, a wireless router can range from a typical 15 dBm (30 mW) strength to 27 dBm (500 mW) on the high end.[6]
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.
This is extremely important for a lot of reasons but will be crucial for any step to reducing radiation. Having a quality EMF meter will allow you to determine what kind of radiation devices in your home are emitted, as well as how much. This will also be crucial in understanding how different changes are improving this I would highly recommend either the TriField TF2 (read my review), or Meterk (read my review) if you need a lower cost EMF meter.
The present study was undertaken to determine the influence of low intensity microwave radiation (900, 1800, or 2450 MHz for 2h/day, 5days/week, for 60 days) on oxidative stress, inflammatory response and DNA damage in rat brain. Low intensity microwave exposure resulted in a frequency dependent significant increase in oxidative stress markers, reduced levels of GSH and SOD, increased levels of pro-inflammatory cytokines, and significant DNA damage in microwave exposed groups compared to controls. In conclusion, the present study suggests that low intensity microwave radiation induces oxidative stress, inflammatory response and DNA damage in brain by exerting a frequency dependent effect. The study also indicates that increased oxidative stress and inflammatory response might be the factors involved in DNA damage following low intensity microwave exposure.
This investigation concerns with the effect of low intensity microwave (2.45 and 16.5 GHz, SAR 1.0 and 2.01 W/kg, respectively) radiation on developing rat brain when exposed for 35 days.  Results showed that the chronic exposure to these radiations caused statistically significant (p<0.001) increase in DNA single strand breaks in brain cells of rat.
Joel Moskowitz (@berkeleyprc) of the University of California, Berkeley School of Public Health, US, says: “This is the largest technological experiment in the history of our species, with potential health risks we still know next to nothing about.” This view is shared by Denis Henshaw, professor of human radiation effects at Bristol University, UK, who said: “Vast numbers of people are using cell phones and this could be a time bomb of health problems.”
