The EMR for cellphones and Wi-Fi is in the microwave range between 300 MHz and 300 GHz (1m to 1mm) and the argument as to the lack of risk from exposure is based on the argument that:

    “Microwaves do not contain sufficient energy to chemically change substances by ionization, and so are an example of non-ionizing radiation … It has not been shown conclusively that microwaves (or other non-ionizing electromagnetic radiation) have significant adverse biological effects at low levels. Some, but not all, studies suggest that long-term exposure may have a carcinogenic effect.” (Wikipedia)

Well, that last sentence is addressed by the paper “Why children absorb more microwave radiation than adults: The consequences”, published in June this year. The authors, L. Lloyd Morgana, Santosh Kesarib, and Devra Lee Davisa summarize how they used computers simulation based on MRI scans of children to model microwave absorption and found:

    Children absorb more MWR than adults because their brain tissues are more absorbent, their skulls are thinner and their relative size is smaller. MWR from wireless devices has been declared a possible human carcinogen. Children are at greater risk than adults when exposed to any carcinogen.

The problem is that the consequences of exposure are anything but immediate:

Because the average latency time between first exposure and diagnosis of a tumor can be decades, tumors induced in children may not be diagnosed until well into adulthood. The fetus is particularly vulnerable to MWR. MWR exposure can result in degeneration of the protective myelin sheath that surrounds brain neurons.

And, of course, the explosion of radio-controlled toys has an effect:

MWR-emitting toys are being sold for use by young infants and toddlers. Digital dementia has been reported in school age children. A case study has shown when cellphones are placed in teenage girls’ bras multiple primary breast cancer develop beneath where the phones are placed.

The paper points out that:

MWR exposure limits have remained unchanged for 19 years. All manufacturers of smartphones have warnings which describe the minimum distance at which phone must be kept away from users in order to not exceed the present legal limits for exposure to MWR. The exposure limit for laptop computers and tablets is set when devices are tested 20 cm away from the body. Belgium, France, India and other technologically sophisticated governments are passing laws and/or issuing warnings about children’s use of wireless devices.

Laws and warnings are all very well but it’s pretty much certain that all restrictions on products that use microwave technology will err on the safe side; that is, the side that’s safe for industry, not the side of what’s safe for society.

Will we look back (sadly) in fifty or a hundred years and marvel at how Wi-Fi and cellphones were responsible for the biggest health crisis in human history?
