In undergoing medical imaging procedures and scans, you may be exposed to Ionising Radiation.
It is the x-ray beam, which, in small doses, allows images of internal structures to be formed and viewed.
It is now common practice to always use the lowest dose that is reasonably possible when taking a diagnostic image.
New technology comes with dose minimisation options, and extremely powerful software which is able to acquire and create detailed images suitable for diagnosis.
How much radiation will I receive from my scan?
Below is a pdf of some basic comparisons for Radiation exposure.
