Doctors and Scientists around the world have warned against unnecessary exposure of children to RF/microwave from wireless technology and recommend safer WIRED internet connection instead, both in school and at home. We are parents who fully support the use of computers and the incorporation of technology in education, and we believe that it must be implemented in a SAFE manner.

iPad User Manual’s Safety Warning and Disclaimer. Have You Read It?

Apple: “Read all safety information below and operating instructions before using iPad to avoid injury.”

Printed copy of the safety information is provided with purchase. However, the manual is a small booklet of 3 1/4″ x 5″. The text is so small that they are practically illegible without magnifying glasses. For a legible copy, consumers have to look it up on the internet. Most parents and teachers never read it.

Here’s what the manual says:

Exposure to Radio Frequency Energy iPad contains radio transmitters and receivers. When on, iPad sends and receives radio frequency (RF) energy through its antenna. The Wi-Fi and Bluetooth® antennas are located behind the screen to the left of the Home button, and behind the Apple logo. iPad has been tested and meets the SAR exposure requirements for Wi-Fi and Bluetooth operation.

A cellular antenna is located at the top edge of iPad Wi-Fi + 3G, when oriented with the Home button at the bottom. For optimal mobile device performance and to be sure that human exposure to RF energy does not exceed the FCC, IC, and European Union guidelines, always follow these instructions and precautions: Orient the device in portrait mode with the Home button at the bottom of the display, or in landscape mode with the cellular antenna (located under the black edge at the top of the device) away from your body or other objects…

If you are still concerned about exposure to RF energy, you can further limit your exposure by limiting the amount of time using iPad Wi-Fi + 3G in wireless mode, since time is a factor in how much exposure a person receives, and by placing more distance between your body and iPad Wi-Fi + 3G, since exposure level drops off dramatically with distance.

The manual warns that if a user does not handle the iPad exactly as instructed, the radiation level will exceed governments’ exposure limits for humans.

Children are targeted for the marketing of such devices, but the safety warning is buried inside an online manual. Without awareness of the warning, parents let children handle the iPads as below. The iPad is often placed on the children’s laps, against their reproductive organs, or in their hands which are touching the antennas.

Instead of treating the iPads as radio frequency transmitters and receivers as declared in the user manual, parents and children treat them as toys.

As explained in a previous post, iPad exposure should be handled with the same caution as cellphone exposure. SAR (specific absorption rate) between cellphone and iPad are similar. Furthermore, peak level radiation of iPad is many times higher than peak level radiation of cellphone.

Similar to what’s admitted in the iPad’s user manual, the World Health
Organization’s “Base stations and wireless technologies Fact sheet” states
that exposure near the “source” of the radiation “may exceed
international exposure limits.”

Offering a child an iPad for hours a day – with WiFi
on, regardless whether the internet is accessed or not – is similar to
giving a child an actively-transmitting cellphone (as during voice calls)
to handle for hours a day.
Pushing for the use of iPads in long duration = pushing for similar
health consequences as seen from heavy cellphone use, except that
it’s now on younger and more vulnerable brains and bodies.
The literature from the WHO and Health Canada, on the “safety” of WiFi,
only covers low-level background signals of routers “from a distance”, it has
no provision for near-field exposure to WiFi-enabled devices such as tablets
and laptops. This is explicitly stated in the wording of their advice.
WiFi microwave signal, be it from a router or from a mobile device, does not
stop until the router is disabled or the WiFi function of the device is turned
off. It does not matter if the user is browsing the internet or not. Parents or
teachers often leave the WiFi function on for convenience and hand the
tablet or smartphone to children for games and apps that do not require
internet connection, not knowing that the radiation continues while the child
is just playing games on the device.
Also, as seen in the user manual, there are multiple antennas embedded at
the back of the iPad. Children or adults definitely should not place it on their
laps.*

* As shown in the video at the bottom of the above page, the measurement
of magnetic fields at the back of the iPad (free of WiFi’s RF signals) shows
that even when the iPad is not on wireless mode, it’s not advisable to place
the unit on the lap.
