You may be concerned about radiation exposure from chest X-rays, especially if you have them regularly. However, the amount of radiation from a chest X-ray is low — even lower than what you're exposed to through natural sources of radiation in the environment.
The X-ray technologists and radiologists use the smallest possible dose of radiation and provide a protective lead apron when multiple X-rays are necessary.
Women should always inform their physician or X-ray technologist if there is any possibility that they are pregnant. Although you should generally avoid X-rays during pregnancy, a lead apron that covers your pelvis and abdomen can minimize radiation exposure to the baby.
