You may be concerned about radiation exposure from chest X-rays, especially if you have them regularly. But 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.

Even though the benefits of an X-ray outweigh the risk, you may be given a protective apron if you need more than one image. Tell your doctor if you're pregnant or might be pregnant. The procedure can be performed in a way to protect your abdomen from the radiation.
