Ionising radiation Study guides, Revision notes & Summaries

Unit 21C Medical Physics Applications Applied Science Btec c: understand health and safety, associated risks, side effects, limitations, of ionizing and non-ionising instrumentation techniques in medical applications. All medical imaging technologies have their own health and safety risks, side effects and limitations both non-ionising and ionising technologies are no exception. MRI:Principles (what is it?) MRI is a non-invasive imaging technique that creates detailed images of the human...

Transverse waves The vibrations are at right angles to the direction of travel. Longitudinal waves The vibrations are along the same direction as the direction of travel. Examples of transverse waves Light and other types of electromagnetic radiation, as well as water waves and S waves (a type of seismic wave). Examples of longitudinal waves Sound waves and waves in a stretched spring, and P waves. Equation linking time, period and frequency Period = 1/frequency Equ...
