Most parents would be concerned if their children had significant exposure to lead, chloroform, gasoline fumes, or the pesticide DDT. The International Agency for Research on Cancer (IRIC), part of the United Nations’ World Health Organization (WHO), classifies these and more than 250 other agents as Class 2B Carcinogens – possibly carcinogenic to humans. Another entry on that same list is radiofrequency electromagnetic fields (RF/EMF). The main sources of RF/EMF are radios, televisions, microwave ovens, cell phones, and Wi-Fi devices.
Uh-oh. Not another diatribe about the dangers of our modern communication systems? Obviously, these devices and the resulting fields are extremely (and increasingly) common in modern society. Even if we want to, we can’t eliminate our exposure, or our children’s, to RF/EMF. But, we may need to limit that exposure, when possible.
That was among the conclusions of a controversial survey article published in the Journal of Microscopy and Ultrastructure entitled “Why children absorb more microwave radiation than adults: The consequences.” From an analysis of others studies, the authors argue that children and adolescents are at considerable risk from devices that radiate microwaves (and that adults are at a lower, but still significant, risk). The following points were offered for consideration:
- Children absorb a greater amount of microwave radiation than adults.
- Fetuses are even more vulnerable than children. Therefore pregnant women should avoid exposing their fetus to microwave radiation.
- Adolescent girls and women should not place cellphones in their bras or in hijabs (headscarf).
- Cellphone manual warnings make clear an overexposure problem exists.
- Government warnings have been issued but most of the public are unaware of such warnings.
- Current exposure limits are inadequate and should be revised.
- Wireless devices are radio transmitters, not toys. Selling toys that use them should be monitored more closely.
Children and fetuses absorb more microwave radiation, according to the authors, because their bodies are relatively smaller, their skulls are thinner, and their brain tissue is more absorbent.

This is not a call to throw out all electronic devices. However, at the very least, it should open up the discussion about different safety levels for adults versus children. Hopefully more longitudinal studies will be done to verify or contradict the assumptions so far. In the meantime, are the government’s current regulations adequate? The exposure levels they warn against haven’t seem to have been updated for more than 19 years.
In a Network World opinion article ominously titled “Is Wi-Fi killing us…slowly?” columnist Mark Gibbs makes the point that “… 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.” Gibbs then added this ominous closing question, “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?”
But, short of that worst-case scenario, the topic certainly merits more scrutiny, and perhaps some common sense limits on what devices our children use, and for how long.
