UNDATED (AP) _ A report says millions of Americans, especially
children, are needlessly getting dangerous radiation from ``super
X-rays'' that raise the risk of cancer and are increasingly used to
diagnose medical problems.
Authors of the report say in a few decades, as many as 2 percent
of all cancers in the U.S. might be due to radiation from CT scans
Some experts say that estimate is overly alarming. But they
agree with the need to curb these tests particularly in children,
who are more susceptible to radiation and more likely to develop
cancer from it.
One study author says while the risk from a single computed
tomography scan to an individual is small, researchers are ``very
concerned about the built-up public health risk over a long period
The study appears in the New England Journal of Medicine.
