Is the radiation from a chest X-ray harmful?

CT emits a powerful dose of radiation, in some cases equivalent to about 200 chest X-rays, or the amount most people would be exposed to from natural sources over seven years. That dose can alter the makeup of human tissue and create free radicals, molecules that can wreak havoc on human cells . Your body can often repair that damage-but not always.
