If you have an x-ray exam that includes tissues or organs that are more sensitive to radiation, your effective dose will be higher. Effective dose allows your doctor to evaluate your risk and compare it to common, everyday sources of exposure, such as natural background radiation.
The low doses of radiation used for imaging tests might increase a person’s cancer risk slightly, but it’s important to put this risk into perspective. Here are answers to some of the more common questions people have about radiation risks linked to imaging tests.
An X-ray (also known in many languages as Röntgen radiation) is a form of high-energy electromagnetic radiation with a wavelength shorter than those of ultraviolet rays and longer than those of gamma rays.
X-rays are a type of radiation that can generate images of tissues and structures inside the body. Although a vital imaging tool, X-rays pose risks and can cause alterations in DNA. X-rays...
An X-ray is a quick, painless test that captures images of the structures inside the body — particularly the bones. X-ray beams pass through the body. These beams are absorbed in different amounts depending on the density of the material they pass through.
X-ray, electromagnetic radiation of extremely short wavelength and high frequency, with wavelengths ranging from about 10^-8 to 10^-12 metre. The passage of X-rays through materials, including biological tissue, can be recorded.
X-rays are a form of electromagnetic radiation, similar to visible light. Unlike light, however, x-rays have higher energy and can pass through most objects, including the body. Medical x-rays are used to generate images of tissues and structures inside the body.
X-rays, formally referred to as radiographs, are common imaging procedures ordered by healthcare providers and dentists. X-ray machines pass x-ray beams (a form of ionizing radiation) through a part of the body to produce images.
There's always questions about radiation exposure from medical imaging. Patients want to know if radiation from mammograms, bone density tests, computed tomography (CT) scans, and so forth will increase their risk of developing cancer. For most women, there's very little risk from routine x-ray imaging such as mammography or dental x-rays.
An X-ray is a type of medical imaging that uses radiation to take pictures of the inside of your body. We often think of X-rays as something providers use to diagnose broken bones or look at your teeth. But X-ray images can also help providers diagnose a wide range of injuries, disorders and diseases.
