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:
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:
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:
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.
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:
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.
