There is no doubt that excessive exposure to X-rays is not safe and when it comes to kids, it is even more important to verify if X-ray or similar test is actually required or not. The same concern has been expressed by the Food and Drug Administration, which is of the view that there is need to protect kids from uncalled-for radiations.

On the same lines, the drug regulator is making efforts to design new scanners which can reduce the radiations exposure without affecting the medical relevance of such medical procedures. There have been concerns shared by parents too about the safety of radiation from medical testing on kids.

"We know imaging is extremely valuable, but we can probably do it with less radiation”, said Dr. Dorothy Bulas of Children's National Medical Center in Washington, while applauding the move made by the FDA.

It is believed that growing tissues in children are more likely to get affected by the exposure of such rays and that’s why this issue is being debated on, so that the possible risk of cancer in kids due to the same can be averted in the first place.

While at times, adjustments are made in scanner doses for youngsters, it is not universally performed and that’s why there is need to ramp up efforts in the same direction.
