"Radiation exposure in childhood is of particular concern because children have immature developing organ and tissue structures," Hill's team wrote in their report, published in the journal Circulation. These kids got an awful lot of imaging — 13,932 X-rays, CT scans and other procedures before, during and after surgery. The X-rays didn't deliver much radiation at all, Hill's team found. The big culprits are cardiac catheterization exams and CT scans. They can deliver up to 1,800 times more radiation than a standard X-ray. Children who got many of these complicated and time-consuming scans did get enough radiation to triple their risk of cancer, Hill found. On average, children don't have a high risk of cancer, though, so even doubling or tripling that very low risk still doesn't make them very likely to develop cancer. "Even though their risk is threefold greater, it is not necessarily a high risk," Hill said. "I think it is important for parents to understand that there is a small amount of risk." Doctors can and should do their best to minimize radiation exposure, Hill said. New technology can help with this, as can techniques that make it necessary to use the shortest possible burst of radiation.
