Are X-ray machines radioactive?
Common materials – X-Ray equipment Radiation – An X-ray machine must be plugged into an electrical source in order to produce radiation. Once you unplug an X-ray machine, there’s no residual radiation. Cobalt 60 – Cobalt 60 is a radioisotope used in radiography and medical applications.
What were the early uses of X-ray?
In 1897, X-rays were first used on a military battlefield, during the Balkan War, to find bullets and broken bones inside patients. Scientists were quick to realize the benefits of X-rays, but slower to comprehend the harmful effects of radiation.
Who can operate a fluoroscopy machine?

For example, in the state of California, a radiologic technologist or a physician assistant must hold a California fluoroscopic permit to participate in fluoroscopic examinations [5,6].
How does fluoroscopy machine work?
A fluoroscope is a special imaging device that produces viewable X-rays without the need to take or develop X-ray photographs. The machine works by passing a continuous X-ray beam through the body part being examined.
What are the five types of radiology?
The most common types of diagnostic radiology exams include:
- Computed tomography (CT), also known as a computerized axial tomography (CAT) scan, including CT angiography.

What is the X – ray machine used for?
X-rays are highly penetrating, ionizing radiation, therefore X-ray machines are used to take pictures of dense tissues such as bones and teeth. This is because bones absorb the radiation more than the less dense soft tissue. X-rays from a source pass through the body and onto a photographic cassette.
What is the function of the X ray machine?
Medical Function. The medical community uses X-rays to examine several parts of the body and to treat conditions.
What is a portable X ray machine?
