How medical X-rays work
Medical X-rays use ionizing radiation to create images inside the body. The FDA recommends that each exam be justified by a clinical need and use the exposure needed to obtain an adequate image.

Useful information before an X-ray
In conventional radiography, a beam passes through the body and the remaining pattern is recorded for later evaluation.
The FDA states that an appropriate exam usually provides a benefit greater than its small risk and should use the exposure needed to answer the clinical question.
Tell the professional before the exam if you are pregnant or think you may be so that it can be considered in the decision.
