X rays use small amounts of radiation. The level of exposure is considered safe for adults. However, it is not considered safe for a developing fetus. Be sure to tell your doctor before the procedure if you are pregnant or believe you could be pregnant. Your doctor may suggest a different testing method that does not use radiation, such as an MRI. If you are having an X ray due to a traumatic event that caused pain and possibly a broken bone, you may experience additional pain during the X ray. The test requires you to adjust your body so that clear images can be taken. This may cause you discomfort. If you are worried, you can ask your doctor for pain medicine prior to your X ray.
