Is it safe to have an X-ray if I'm trying for a baby?
No-one really knows what is the 'safe' level of radiation exposure during pregnancy so it is sensible to avoid X-rays unless absolutely necessary. The dose of radiation of the most common X-rays (such as dental or chest) is quite small, and if you are pregnant then the radiographer will give you a lead shield to wear over your tummy. This will stop X-rays from getting through. Generally speaking, however, if you are or could be pregnant then you should probably not have an X-ray unless it is essential for a medical reason. It is more important to avoid X-rays when the main organ systems of the baby are forming (ie in the first thirteen weeks of pregnancy) than later on. Occasionally an X-ray (or CT; computerised tomography) to determine the size and shape of the pelvis is performed in late pregnancy; this requires only a low dose of radiation.
