Uh-oh. Not another diatribe about the dangers of our modern communication systems? 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 report 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). 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. They also note that the average time between exposure to a carcinogen and a resultant tumor is three or more decades, thus making it difficult to arrive at definitive conclusions. 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. In a Network World opinion article ominously titled "Is Wi-Fi killing usslowly?" 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 side that's safe for industry, not the side of what's safe for society."
