Dear School Board Members:
I wish to bring to your attention a press release I distributed today as it is relevant to the District's Technology Plan. At a recent meeting, the Board decided to adopt a Wi-Fi system in the LA Unified schools against the recommendations of some American health experts as well as the Council of Europe:
As you may know, the FCC's regulatory standard protects the population from thermal exposure to microwave radiation from wireless equipment but not from low-intensity, non-thermal exposures.
Since the District ignored these warnings and intends to install wireless networks in the schools, I suggest you consider a requirement that the systems be designed consistent with the ALARA (as low as reasonably achievable) principle in order to minimize potential health risks to students and staff. It would be prudent for the Board to follow this course of action based upon the precautionary principle.
In 2003, a major telecommunications company acknowledged in a patent filing that exposure to low intensity, non-thermal wireless radiation is carcinogenic. The technology described in this patent could substantially reduce microwave radiation exposure from a local wireless network. Although I have not done a patent search, I would imagine that the wireless industry holds numerous patents that could reduce microwave radiation exposure from wireless local networks. Unfortunately, the industry has little incentive to apply these patents to extant technology because the FCC has been lax in its regulation of microwave radiation.
The District could become a model for the nation by adopting a Wi-Fi system and distributing tablets/laptops that are compliant with the ALARA principle. School districts and their students throughout the country could also benefit if the Board requires the wireless industry to make this option available to the public.

Wireless Industry's Patented System to Reduce Cancer Risk from Wireless Local Networks Never Adopted
A major telecom company patented a system to reduce "electrosmog" from wireless local networks to reduce cancer risks associated with non-thermal exposures to microwave radiation. The industry has known the risks for many years but has failed to act. Joel M. Moskowitz, PRLog (Press Release) - Mar 11, 2013
Swisscom AG, a major telecommunications provider in Switzerland, filed U.S. and international patent applications for an innovative system to reduce “electrosmog” from wireless local networks (i.e., Wi-Fi) in 2003.
This patent application acknowledged the cancer risk from exposure to wireless radiation eight years before the WHO’s International Agency for Research on Cancer declared that radiofrequency energy, including cell phone and Wi-Fi radiation, is a “possible carcinogen” to humans, like DDT and lead.
Furthermore, the application acknowledged that low-intensity, non-thermal exposures to wireless radiation is genotoxic. This is critical because the current U.S. regulatory standard for wireless radiation, established in 1996, does not protect us from non-thermal exposures ...

March 7, 2013 Update
Last night, the Los Angeles Teacher’s Union adopted a resolution to ensure safety from hazardous electromagnetic fields (EMF) in schools including EMF emissions from wireless technology.

The Los Angeles Unified School District plans to spend $500 million to install Wi-Fi in every classroom and provide every student with a tablet or laptop.
Excerpts from Selected Letters
“We note that the American Academy of Pediatrics has expressed its concerns about the growing exposures to children in a letter to Congress dated 12 December 2012: ‘Children are disproportionately affected by environmental exposures, including cell phone radiation. The differences in bone density and the amount of fluid in a child’s brain compared to an adult’s brain could allow children to absorb greater quantities of RF energy deeper into their brains than adults. It is essential that any new standards for cell phones or other wireless devices be based on protecting the youngest and most vulnerable populations to ensure they are safeguarded through their lifetimes.'”
"As many researchers have noted, children are not merely little adults. Their brains and skulls absorb more radiation than do adults. Empirical data have shown a difference in the dielectric properties of tissues as a function of age, mostly due to the higher water content in children's tissues. High resolution computerized models based on human imaging data suggest that children are indeed more susceptible to the effects of EMF exposure at microwave frequencies."
"Please be aware that national authorities in France and Israel are advising against wi-fi expansion, especially in schools with younger children. Many authorities have noted that standards for wireless exposures differ by several orders of magnitude, with those in the home country of the World Health Organization, Switzerland being among the most stringent in the world."
"In fact, research on this topic remains poorly funded in the U.S. The absence of definitive information on risks from wi-fi in the U.S. at this time should not be interpreted as proof of safety."
"Wired systems are far more safe, secure, and speedy, and avoid potential long term public health issues. In addition, wired systems will protect the growing number of persons who are hypersensitive to wi-fi exposures, as well as limit risks to persons with pace-makers or those with other implanted electronic or metal devices that can absorb greater amounts of such radiation."
“EMF/RFR from wifi and cell towers can exert a disorganizing effect on the ability to learn and remember, and can also be destabilizing to immune and metabolic function. This will make it harder for some children to learn, particularly those who are already having problems in the first place.“
