WebApr 5, 2024 · X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10 −8 to 10 −12 metre and corresponding frequencies from about 10 16 to 10 20 hertz (Hz). WebA chest X-ray, by comparison, emits 0.02 mSv of radiation. CT and PET scans emit more radiation and tend to last at least a few seconds. An abdominal CT scan exposes you to between 8 and 10 mSv of radiation, while a coronary CT angiogram exposes you to 16 mSv. And a PET scan, used to detect cancer, issues roughly 25 mSv of radiation.
