Stop Wi-Fi in Schools – Sample Letter

Spread the love

Dear Director XYZ

Today, we are writing to advise you of the scientific grounds for taking action to mitigate student, teacher and staff exposures to Wi-Fi and other non-ionizing electromagnetic fields in schools.

Wireless radio frequency (RF) electromagnetic (EMF) radiation and magnetic field/ extremely low frequency electromagnetic fields (ELF-EMF) are a relatively new and rapidly increasing environmental exposure in classrooms today. A substantial body of research has found these types of non-ionizing EMFs  associated with numerous adverse effects including cancer, DNA damage, memory damage, headaches,  reproductive damage, tumor promotion, blood brain barrier damage, increased oxidative stress, impacts to the endocrine system, brain damage.1 Many of these effects could be irreversible with grave consequences for our children’s future.

By eliminating unnecessary emission sources on school property, you can substantially mitigate the risk and lower exposure levels. A few specific examples of in-school sources are Wi-Fi, wireless networks, chromebooks, electronics, electrical systems, cordless phones, and cell phones.

In addition we caution against 5G devices. 5G is the latest technology and is already being field tested in schools. The wireless industry has long pushed  Wi-Fi in schools nationwide and is now proposing expanding 5G into classrooms,2 arguing3 that “augmented reality” and “virtual reality” are “essential tools” in classrooms.4

The peer-reviewed published research clearly shows that compliance with Federal Communications Commission (FCC) regulations regarding human exposure to radiofrequency does not ensure the safety of students and staff. More protective regulations to mitigate, monitor, investigate, and educate are moving forward in the U.S. and internationally5. In addition, PTAs and teacher unions are now responding to the strong recommendations by medical organizations, such as the American Academy of Pediatrics, by educating and supporting policy and resolutions on minimizing cell tower, cell phone and wireless radiation in classrooms.

Both magnetic field (2002) and radiofrequency radiation (2011) were classified6,7as a Group 2B possible carcinogen by the World Health Organization International Agency for Research on Cancer (IARC). However, since these determinations years ago, the published peer-reviewed scientific evidence has significantly increased– clearly showing these types of non-ionizing electromagnetic radiation have adverse effects at emission levels governments currently allow.8,9,10,11 Current published research has documented that the evidence is robust to now determine that RF is a proven human carcinogen.12,13,14

Numerous published scientific reports recommend that the public, especially children and pregnant women, reduce their exposure to non-ionizing electromagnetic radiation in order to protect their health- including the frequencies that range from  extremely low frequency fields, to all wireless and the higher frequencies of 5G.15,16,17,18,19,20,21,22,23

Our children are at risk. Research shows that this type of radiation penetrates deeper and more intensely into children due to their thinner skulls and unique physiology. Furthermore, wireless radiation has been shown to damage brain development and is associated with attention, memory and behavioral problems24. The American Academy of Pediatrics has repeatedly written to the FCC on the need for an update to the FCC’s 1996 wireless exposure regulations because children are more vulnerable to the exposure.25

Electromagnetic radiation exposure presents occupational health issues for teachers and staff, which are especially critical for those who are pregnant or have medical conditions. Yale research26 found thyroid cancer to be associated with cell phone use in people with genetic susceptibility.  Prenatal radiofrequency radiation exposure led to higher hyperactivity, poorer memory, and altered brain function in mice,27 corroborating prior published research findings of altered brain development after exposure.

Kaiser Permanente researchers have published several studies where pregnant women’s exposure to non-ionizing electromagnetic fields was associated with increased miscarriage as well as increased ADHD, obesity, and asthma in prenatally exposed children. 

Due to the scientific evidence showing adverse effects from wireless and electromagnetic radiation at legally allowed levels,28,29,30,31,32 we have joined with hundreds of doctors and scientists33 calling to halt 5G34 and to reduce children’s overall wireless and non-ionizing electromagnetic radiation exposure. We recommend practical and actionable measures to eliminate and reduce exposures in the school setting.

Safe alternative solutions exist to connect students to the Internet, bridge the digital divide, and ensure equal access. Corded connections in classrooms rather than wireless networks are safer, faster, more secure, and do not pose the serious liability risks posed by EMFs and RF radiation.

Importantly, 5G and cell antennas should not be installed on or near schools.

Many countries and schools are taking action. More than 20 countries clearly recommend children reduce cell phone radiation. Cyprus, Belgium, France, and Israel are among the countries banning and restricting Wi-Fi in classrooms and many private schools world-wide35 have started reducing EMF exposures. New Hampshire37 launched an investigation into the health effects of electromagnetic radiation and released their final report with 15 recommendations including the recommendation that schools  reduce radiofrequency radiation and replace Wi-Fi with wired networks in classrooms.

In regards to ELF-EMFs, over a dozen countries already have some level of protective policy in place with a magnetic field radiation limit for  “sensitive areas” that ensures ELF-EMF levels do not exceed levels associated with cancer in research studies. Aside from the California Department of Education regulation that requires distances between new schools and the edge of a transmission line “right-of-way”, there exists little protections in the USA for schools as there is no federal limit for human exposure to magnetic field electromagnetic fields.

We recommend the Secretary of Education provide nationwide guidance on Best Practices to Reduce EMF for schools and colleges including:

  1. Install a safe wired ethernet communication and information technology infrastructure in schools to meet educational needs: Solutions exist to eliminate Wi-Fi/5G/4G and reduce exposures to wireless emissions in classrooms. Educational needs can be met corded telephones in classrooms and safer wired internet connections instead of Wi-Fi and wireless connections.
  2. Measure radiofrequency, magnetic field and extremely low-frequency electromagnetic fields and reduce levels to as low as possible. Publicly post all results online.
  3. Ensure school property is not located close to 5G/cell towers, cell network antennas, or electricity substations of high-voltage power lines. 
  4. Dormitories should have wired, not Wi-Fi connections and corded telephones for students in every room.
  5. A school community awareness campaign about cell phone and other wireless radiation through new educational curriculum on how to reduce EMF: Students, teachers, and their families should be given clear information on why and how to reduce exposures to cell phone, wireless and magnetic field EMF’s to protect their health. 

We are aware that many schools and colleges are opting for virtual and/or hybrid classes. We recommend this as an opportunity to install wired technology while students are away from the buildings. In a world where our health is threatened by a rising pandemic, we must stop at nothing to mitigate any external health threats facing our youth. This means eliminating in-school sources of radiofrequency radiation, providing the necessary equipment for students to connect to online school with wires, and educating students on preventative measures they can take to reduce radiation themselves. Most importantly, however, this means taking steps toward a healthy school environment in which each student thrives.

Our suggestions that we have to reduce radiation exposure during virtual and/or hybrid school year include:

  • Ensure that students have the hardware and software to hardwire internet connections (instead of Wi-Fi or wireless hotspots) for virtual school at home.
  • Educate students on how to hook up their devices with an ethernet connection and reduce cell phone and wireless exposures.
  • Purchasing departments can request hardware to have devices that can be hardwired.
  • Educate students and staff on the importance of keeping devices off their laps and away from their bodies.

Please see our recommendations to the U.S. Department of Education below.  These recommendations can be used in any country at the federal level to protect schoolchildren.

We call for federal action to ensure safety including:

  1. Call on the Environmental Protection Agency to develope of science-based safety limits for children’s exposures to RFR and magnetic field non ionizing EMF. The allowable human exposure limits for RFR  were adopted  in 1996 and have not changed since then. The EPA should develop safety limits based on a systematic review of the full body of scientific research including cancer and impacts to the brain and reproduction.  The United States must also develop exposure limits on magnetic field EMF and other frequencies in the non-ionizing range used in electricity distribution, wireless power transfer and other applications. Currently there are no safety limits for school EMF exposures.
  2. Develop a national educational technology policy on Best Practices for Digital Devices in Schools that addresses the social, emotional and physical effects of screens. In addition to students learning how to minimize the health effects of screens, school practice and curriculum should adhere to best practices developed for various age groups that minimizes health effects to students, teachers and staff.
  3. Call on the Department of Occupational Safety and Health to urgently address EMF as an environmental occupational exposure in classrooms. An evaluation of current and projected occupational exposures in classrooms and educational settings is needed. Occupational exposure limits for the classroom setting need to be developed. Practical measures to reduce exposures is critical to supporting the health of teachers and staff.
  4. Recommendations for No/Low EMF purchases. Develop a list of school technology hardware and software changes that will eliminate or reduce EMF exposures in classrooms. For example, tablets and laptops should have a convenient ON/OFF hard switch for Wi-Fi and an ethernet port so using ethernet is convenient.  Overhead projectors and printers and other educational technology should have Wi-Fi to OFF as the default setting. 

The Risk of Inaction is High

Wi-Fi, cell phones, and 5G in the classroom as well as cell towers on school property present serious liability issues.

  • Insurers rank 5G and electromagnetic radiation as a “high” risk, comparing the issue to lead and asbestos.38,39 A 2019 Report by Swiss Re Institute, a world leading provider of insurance,42 classifies 5G mobile networks as a “high”, “off-the-leash” risk stating, “Existing concerns regarding potential negative health effects from electromagnetic fields (EMF) are only likely to increase. An uptick in liability claims could be a potential long-term consequence” and “[a]s the biological effects of EMF in general and 5G in particular are still being debated, potential claims for health impairments may come with a long latency.”
  • Due to their understanding of the magnitude of this future financial risk most insurance plans have “electromagnetic field exclusions” applied as the market standard.40  Portland Oregon Public School Insurance41  (Pg 30) states as an example, ”Exclusions: This insurance does not apply to: Bodily injury, personal injury, advertising injury, or property damage arising directly or indirectly out of, resulting from, caused or contributed to by electromagnetic radiation, provided that such loss, cost or expense results from or is contributed to by the hazardous properties of electromagnetic radiation.”
  • US Mobile operators have been unable to get insurance to cover liabilities related to damages from long term exposure to radiofrequency emissions for over a decade.
  • Wireless and non ionizing electromagnetic radiation are defined as a type of “pollution” by wireless companies themselves. According to pg. 10 of the  Verizon Total Mobile Protection Plan, “Pollution” is defined as  “The discharge, dispersal, seepage, migration or escape of pollutants. Pollutants means any solid, liquid, gaseous, or thermal irritant or contaminant including smoke, vapor, soot, fumes, acid, alkalis, chemicals, artificially produced electric fields, magnetic field, electromagnetic field, sound waves, microwaves, and all artificially produced ionizing or nonionizing radiation and/or waste.” We found similar definitions for pollution in the product protection plans for AT&T, Sprint, Verizon, T-Mobile and Asuria.
  • Wireless companies warn their shareholders of this potential future risk related to radiofrequency radiation exposure but they do not warn the users of these products, nor do they warn the people exposed to emissions from their products and infrastructure. These corporate investor warnings by companies such as  AT&T, Verizon, Vodaphone and Crown Castle  are contained in their Annual Reports filed on Form 10-K (or Form 20-F or 40-F for foreign companies) with the Securities and Exchange Commission (SEC) and they clearly inform shareholders that companies may incur significant financial losses related to electromagnetic fields. Safety is not assured.

As an example, Crown Castle states in their 2020 Annual Report, “If radio frequency emissions from wireless handsets or equipment on our communications infrastructure are demonstrated to cause negative health effects, potential future claims could adversely affect our operations, costs or revenues. The potential connection between radio frequency emissions and certain negative health effects, including some forms of cancer, has been the subject of substantial study by the scientific community in recent years. We cannot guarantee that claims relating to radio frequency emissions will not arise in the future or that the results of such studies will not be adverse to us…If a connection between radio frequency emissions and possible negative health effects were established, our operations, costs, or revenues may be materially and adversely affected. We currently do not maintain any significant insurance with respect to these matters.”

We have attached to this letter the following resources and tools you can use to address these environmental exposure in schools:

  • The Collaborative for High Performance Schools (the United States’ first green building rating program especially designed for K-12 schools) developed Best Practices for Low-EMF classrooms in 2014, addressing both wireless and ELF-EMF.43 
  • In 2017, the Maryland State Children’s Environmental Health And Protection Advisory Council issued first ever state recommendations for reducing wireless exposure in schools by providing wired—rather than wireless—Internet connections.
  • The New Jersey Education Association article, “Minimize Health Risks from Wireless Devices”44 details several recommendations for reducing the health risks posed by wireless technology, such as “Keep devices away from the body” and “hard wire all devices, including printers, projectors and boards.”Download PDF.45
  • Guidelines for Safer Use of Wireless Technology in Classrooms” were developed for the New York State United Teachers, who also passed a Resolution “Hazards of Wireless Radiation Emission.”46,47
  • The United Educators of San Francisco (teacher Union) passed a resolution recommending the California Department of Public Health issued guidance on how to reduce exposure to cell phone radiation be disseminated to all students and staff.50,51
  • Education modules were developed in partnership with the Massachusetts Breast Cancer Coalition to teach high school and middle schoolers about why and how to reduce radiation from cell phones and wireless devices.52
  • A 2017 study found the environmental exposure to RF radiation in some schools with Wi-Fi is higher than reported levels for non-thermal biological effects and the researchers recommend schools prefer wired network connections and  allow laptop, tablets, and mobile phone usage only in flight/airplane mode and this was followed by a 2019 publication in the industry journal Building and Environment details best practices in buildings to reduce radiofrequency as including wired technology instead of Wi-Fi and corded phones.48
  • Environmental Health Trust has developed a checklist of actions for schools to reduce EMF.49

We offer our expertise to support you in making these changes. Please see the attached resources with additional documentation. We are available to meet with your leadership to present how to reduce and mitigate the risks of radiation exposure. Thank you for your consideration and action on this issue.
