Radiography
What is Radiography?
​
Radiography is the most recognisable form of x-ray scan. Its result is a 2- dimensional image of the body part.
​
X-rays are produced (Production of X-rays) and directed towards a detector which may be a photo-film or digital detector. The body part to be scanned is placed in the path of the x-rays. Different tissues absorb more x-rays that others meaning less x-rays are detected by the detector. Bone is said to be ‘radio-dense’ because it absorbs more x-rays than other tissues such as fat and muscle. Body parts that absorb more radiation show up lighter on the image. This is why x-rays are useful to detect bone fractures and breakages. [X3]
Safety
According to radiologyinfo.org, the average effective radiation dose for an x-ray scan of an extremity is 0.001mSv which is the equivalent of 10 bananas. (Click on our banana scale page for more information). [X4]
