While X-rays are linked to a slightly increased risk of cancer, there is an extremely low risk of short-term side effects. Exposure to high radiation levels can have a range of effects, such as vomiting, bleeding, fainting, hair loss, and the loss of skin and hair.

How many X-rays are dangerous?

While there's no magic number of how many X-rays are safe in each year, the American College of Radiology recommends limiting lifetime diagnostic radiation exposure to 100 mSv, which is the equivalent to about 10,000 chest X-rays, but only 25 chest CT scans.

Can X-rays cause cancer?

X-rays are common medical imaging tests. They use a type of radiation called ionizing radiation. This type of radiation can lead to cancer but only in higher doses. Medical tests that involve X-rays generally expose us to only small amounts of radiation.
