When doctors first ordered a CT scan for Jen Houck's six-month-old daughter in 2003, the new mom was more worried about the risks of anesthesia (used to keep children from squirming in the machine) than of radiation exposure. In 2006 and 2007, her daughter, now 5, had two additional CT scans, 6 months apart, for what doctors initially thought was a growth abnormality. They've since determined the child was perfectly healthy. "All that, just to find out her head is bigger than normal," says the 27-year-old mother of two in Boone, North Carolina...
...exposed to roughly the same amount of radiation as two CT scans. Based in part on those studies, the Food and Drug Administration estimates that an adult's lifetime risk of developing radiation-induced cancer from a CT scan is roughly 1 in 2,000. Worse, the risk for children is even higher...
Compared with adults, children are more sensitive to radiation because they have longer life expectancies and because their cells divide more rapidly, making their DNA more vulnerable to damage. A child's risk of developing a fatal cancer from one CT scan is as high as 1 in 500. Although newer machines can be adjusted to deliver up to 50% less radiation for children and small adults, a 2001 study published in the American Journal of Radiation showed that radiologic technologists (RT) rarely make those adjustments. "Changing technical factors is very easy. It just requires a little thought...
...heard from thousands of Americans now who have wrestled with the meaning of patriotism and come to a clearer sense of purpose about what kind of America they want their children to inherit. We've launched a national high school essay contest about true patriotism and have been astounded by the range and depth of the responses (you can learn more at www.truepat.org). The larger this conversation gets, the less partisan it becomes...
Blair seems resolute to meet the climate challenge, and he has the right ideas. "If you've got children, you want them to grow up in a world that doesn't have catastrophic climate change," he said. But after a few more months of hitting his head against the climate wall, he might want to spend his retirement years working on something a bit easier. Like Mideast peace...
