There is little risk to health from one x-ray, but with repeated tests there is a risk that the radiation may damage body cells, possibly leading to cancer in the future. There is only a risk if you have a high number of x-rays; one every other year is not harmful.

If an x-ray is justified necessary, the dose of radiation is always kept as low as possible and the reproductive organs are shielded. Radiographers wear a lead apron or go behind a protective screen to avoid repeated exposure to x-rays. The earlier in life you are exposed to radiation, the greater the risk.

Women who are, or are likely to be pregnant, should not have an x-ray, especially in the first three months when the foetus is growing rapidly. There is a small risk of causing harm to the unborn baby, depending on the type of x-ray, the level of dosage and the part of the body being x-rayed (i.e. pelvis or abdomen).

You will be asked for the date of your last period before you have an x-ray; this is to check that there is no chance you could be pregnant. If possible, you should postpone the x-ray until after your baby is born. But if you do have an x-ray and later discover you are pregnant, the risks are not high enough to have to terminate the pregnancy (1).
