The 203,520-member New Jersey Education Assn. says devices such as cellphones, computers and Wi-Fi are “ubiquitous in schools” but “threaten the physical and mental health” of teachers and staff.

The September NJEA Review has the following advice:

NJEA logo--Keep devices away from body and bedroom.

--Carry phones in briefcases, etc., not on the body.

--Put devices on desks, not laps.

--Hard wire all devices that connect to the internet.

--Hard wire all fixed devices such as printer, projects, boards.

--Use hard-wired phones instead of cell or cordless phones.

--Text rather than call.

--Put devices in airplane mode, which suspends EMF transmission, thereby disabling Bluetooth, GPS, phone calls and Wi-Fi.

--Use speaker phone or ear buds instead of holding the phone next to your head.

--Take off Bluetooth devices when not using them.

NJEA, with 203,520 members, is headed by Wendell Steinhauer, president, high school mathematics teacher in Riverside public schools. Edward Richardson is executive director. Authors of the article are Adrienne Markowitz and Eileen Senn.

Revenues in the year ended Aug. 31, 2014, latest available on GuideStar, were $129.6 million. Expenses were $128.5M. Assets totaled $145M and liabilities, $162.7M, resulting in minus $17.5M in “assets.” EIN is 21-0524390.

Executive director Edward Richardson was paid a total of $703,927; Steinhauer, $454,369; info system mgr. Bruce Ionno, $818,112; asst. executive dir. Rich Gray, $721,139, and Zella Felzenberg, assistant director, UNISER, $658,317. Dues are $866 for teachers; $433, part-time professionals, and $985 for professional life members.

No Call for Router Shutdown

The article does not call for a shutdown of Wi-Fi routers in the classrooms, a demand that is being made by some teachers in other states and abroad.

David Morrison, who operates wirelessblogspot has said that more than one million teachers in unions in the U.S. Canada, U.K. and Germany have asked that Wi-Fi routers be shut down in their classrooms.

“Students are subject to microwave radiation seven hours a day,” he said.

in protesting the refusal of the National Parent Teachers Assn. to allow Wi-Fi health advocates to have an exhibit at the national conference June 30-July 4 in Orlando.

Martin Weatherall, co-director of Wireless Electrical and Electromagnetic Pollution (WEEP), in an email to PTA chapters, said he was “disgusted” by PTA’s refusal to “educate conference participants about the dangers of powerful microwave radiation that is likely to cause the children long term health problems.” He cited “a huge increase in mental health problems, depression and suicide among children since their exposure to wireless radiation in schools and homes.”

Rose Acerra is president of the New Jersey Parent Teachers Assn. She has been asked if NJPTA has any comment on the statement by NJEA.

NJEA Lists Radiation Sources

The NJEA listed the following radiation sources: desktop computers, laptops, tablets, eBook readers, printers, projectors, smart boards, smart TVs, cellphones, cordless phones and Wi-Fi wireless networks.

Such devices “have become ubiquitous in schools,” says NJEA. “At their best, they are powerful tools for education. At their worst, they threaten the physical and mental health of teachers, paraeducators, secretaries, librarians and other school staff members and students who spend numerous hours using the devices.

“Physical health risks from electronic devices include pain and tingling from repetitive strain injuries to the hands and wrists; pain in the neck, shoulders and back; dry, burning, itchy eyes, blurred vision and headaches; altered sleep patterns and next-day fatigue from exposure to blue screen light; distracted driving; and various health problems from exposure to radiation.

“Mental health risks arise from stress due to raised expectations for multitasking, productivity and proficiency with devices; dealing with malfunctioning devices; student and colleague distraction from and addiction to devices; and intrusion of devices into nonwork time.

Devices Emit Radiation

“Radio frequency (RF) electromagnetic frequency (EMF) radiation is sent and/or received by the antennae of phones, routers and other wireless devices. RF radiation is capable of causing cancer, reproductive, neurological and ocular effects.

“The amount of radiation exposure received depends on the amount of time exposed and distance from the source. Radiation levels fall off exponentially with distance from antennae. If you double the distance, the radiation is four times less. If you triple the distance, it is nine times less, and so on. Children and developing fetuses are particularly at risk because their bodies are still growing. People with implanted medical devices are at risk for device interference.”

Cut Use, Max Distance

NJEA’s advice is to minimize use of the devices and maximize distance from them.

Other advice from the announcement follows.

For repetitive strain injuries

▪ Use voice control/speech recognition.

▪ Use ergonomic alternatives to traditional mice and keyboards.

▪ Use as many fingers as possible when typing and both thumbs when texting.

For neck, shoulder and back pain

▪ Ensure an ergonomic workstation.

▪ When using a hand-held device, support it and the forearms.

▪ Avoid bending the head down or jutting it forward.

▪ Take frequent, short breaks from the device.

▪ Ensure good posture and change positions frequently.

▪ Stand and do stretching exercises.

For eye pain, blurred vision and headaches

▪ Use sufficient, but not excessive, lighting.

▪ Use assistive technology built into Apple, Android and Windows devices.

▪ Enlarge and darken the cursor and pointer.

▪ Enlarge the font; magnify the text.

▪ Use text-to-speech instead of reading.

▪ Use special computer glasses.

▪ Relax the eyes on a minibreak.

For altered sleep patterns and next-day fatigue

▪ Stop using devices at least one hour before bedtime.

For distracted driving

▪ Use hands-free devices, preferably speakerphones.

▪ Pull over and park.

▪ Let someone else drive.

Cell phones and cancer

The National Toxicology Program (NTP) is conducting the largest set of laboratory rodent studies to date on cellphone RF radiation. The studies cost $25 million and are designed to mimic human exposure. They are based on the cellphone frequencies and modulations currently in use in the United States.

The NTP studies are designed to look at effects in all parts of the body.

On May 27, 2016, NTP released a report with partial results of the studies. They found increased occurrence of rare brain tumors called gliomas and increases in nerve tumors called schwannoma of the heart in male rats. The released results are partial because more rat studies and all of the mouse studies will be forthcoming by 2017. The cells that became cancerous in the rats were the same types of cells as those that have been reported to develop into tumors in human cellphone users.

The EMF produced by cellphones was classified as possibly carcinogenic to humans by the World Health Organization in 2011. They found that long-term use of a cell phone might lead to two different types of tumors, gliomas and acoustic neuroma, a tumor of the auditory nerve.
