Are Wi Fi Systems in Schools Safe?

There has been a worldwide shift in thinking about the safety of the widespread adoption of  Wi-Fi systems for internet access in schools. These systems are convenient, however they use similar radio frequency electromagnetic radiation (RF EMR)  frequencies as cell phones, cordless phones and microwave ovens. Although at lower power, these microwaves pass through the body and can affect fragile biological processes during development. Children absorb more brain radiation due to thinner skulls. Parents, teachers and researchers are concerned that kids are being exposed to harmful radiation continuously without consideration of adverse long term health effects, effects on learning and concentration as well as related psychosocial issues with privacy, security, commercialism, social media and internet addiction. Many community and parent  groups have organized to oppose Wi-Fi in local schools, arguing that wiring schools is safer, more secure and cheaper.

Children’s Nervous Systems Are Not Fully Developed

This is a critical discussion as children are not fully developed, especially with regards to their brains and nervous system connections. Children’s skulls are thinner as well and thus absorb more radiation. Pediatrician, Dr. Lisa Thornton, has health concerns with cell phones. Their reproductive systems are also at risk with close exposure to wireless devices. Some schools, especially in Switzerland and Germany, are moving toward fiberoptic and wired systems to protect both the health of as well as the privacy of students. Many schools in the U.S. are beginning to prohibit cell phone use of students during school hours. Universities and law schools are banning the use of laptop computers in class due to distraction. Despite these efforts many K-12 schools in the United States embrace and are expanding wireless and online technologies, including in charter schools. The Environmental Health Trust has complied a list of government, health agency and school policies to reduce EMR exposure in public spaces.  International Actions on Wireless Radiation

FCC Safety Guidelines for Wireless Radiation are Outdated

Federal Communications Commission (FCC) guidelines for RF EMR are based on a short 30 minute exposure to a device and do not take into account long term health effects, additive effects of multiple devices, synergistic effects with other toxic exposures, and sensitive populations such as those with chronic illness or electrosensitivity.  FCC safety guidelines are also based only on heat and not biological effects identified in research studies. Scientists worldwide who have studied radio frequency radiation have called for reevaluation of the outdated safety standards set by the FCC in 1996 with the passage of the Telecommunications Act.

Schools are Removing Wireless and Returning to Wired Connections

Many schools  in Europe have removed Wi-Fi and laws in France, Israel and Austria ban Wi-Fi in schools in preschools and the younger grades. For a full list of schoolvisit  In the United States, The Collaborative for High Performing Schools  who have policies for schools to improve student performance through improved building design have developed a section on Best Practices for a Low EMF Environment in 2014. This well researched and well written policy document includes recommendations for the

  • wiring of WLAN networks
  • Keeping computers and tablets away from the body
  • Prohibiting cell phones and other personal wireless devices in the classroom

New Jersey Education Association Advises Lowering EMF in Schools

The New Jersey Education Association (NJEA) in September 2016 wrote guidelines for their schools explaining the potential harm from non ionizing radiation emitted from wireless devices and use of digital technology. NJEA offers precautionary advice. They include recommendations to minimize

  • Repetitive Strain
  • Neck and back Pain
  • Blurred vision and headache
  • Altered sleep patterns
  • Radiation exposure from devices by hardwiring computers, printers, phones, projectors and boards classrooms

Ashland Public Schools “Best Practices for Mobile Devices”

Ashland Public Schools in Massachusetts adopted a “Best Practices for Mobile Devices” policy in 2015 after reviewing the research on EMR. The effort was lead by Cece Doucette who initially worked on funding to get Wi Fi and wireless devices in the school system. After learning of the potential health hazards she became an advocate to remove Wi-Fi in schools.  Here is the Ashland poster placed in each school room Best Practices to Reduce EMR. The  “Best Practices” policy includes the following recommendations.

  • Turn off the device when not in use
  • Turn Wi-Fi on only when needed
  • Always place the mobile device on a solid surface
  • Viewing distance should be a minimum of 12 inches from the screen
  • Specific product information guides are available through the IT department
  • Staff members should regularly remind and instruct students in using best practices in regards to mobile devices


Physicians Speak Out on Wi fi In Schools 

Well known physicians who have studied the health effects of  radio frequency radiation, Dr. Martha Herbert and Dr. David Carpenter, have long questioned the safety of  cell towers and wireless networks in schools. They have advocated for safer wired networks. Others have joined them as more research is pointing to harm.

Parents Speak Out on Wi Fi in Schools

Charlene Acres Describes Her Daughter’s Development of Electrosensitivity at School

Charlene Acres is a computer scientist and mother who clearly describes her daughter’s development of electrohypersensitivity (EHS) when at school.  Her daughters symptoms were severe headaches and fatigue. They found that the cell towers near school and addition of wireless systems in school caused the symptoms. The levels of Electromagnetic radiation measured in the school were within the Safety Code 6 regulations. This is a compelling and useful story to help understand EHS which is well documented. Most physicians were not able to diagnose or treat this condition.

Physicians Speak Out

Dr. David Carpenter on Wi Fi in Schools

Dr. David Carpenter is a Harvard trained public health physician and Director of the Institute for Health and the Environment at University of Albany. He has more than 435 peer reviewed publications. He discusses the need to remove Wi fi in schools to reduce their risk of cancer.  Dr. Carpenter  suggests wired connections for schools.

Advisory Boards

Maryland Children’s Environmental Health and Protection Advisory Council

In December 2016 the MCEHPAC  issued a “Wifi Radiation in Schools in Maryland Final Report”. This state agency is tasked with identifying environmental health issues that impact children and to protect them from exposure to environmental hazards. Under their state code Md. Code Ann., Health-General §13–1506,  their responsibilities include

  • Gather and disseminate information to the public, including the research and medical communities, community–based organizations, schools, and State agencies, on how to reduce, treat, and eliminate children’s exposures to environmental hazards to further the public’s understanding of the environmental hazards that may potentially affect children;
  • Recommend uniform guidelines for State agencies to follow to help reduce and eliminate children’s exposure to environmental hazards, especially in areas reasonably accessible to children…

After gathering abundant testimony,  including that of former IARC member Dr. Anthony Miller,  the Advisory Board for Marland Children’s Health  and with transparent discussion the Maryland Children’s Environmental Health and Protection Advisory Council  Report recommendations include

  • Formally petition the FCC to revisit the exposure limits to wireless radio frequency radiation
  • Consider using wired devices in those already wireless and design classrooms with wired connections.
  • Have children place devices on desks to serve as barrier between the device and children’s bodies.
  • Teach children to turn off WiFi when not in use.
  • Consider placing routers as far away from students as possible.
