What is the intensity of an x-ray beam?
Amount of radiation per unit time and area
What is the quality Of a beam?
A measure of the penetrating power
The exposure ?
Amount of radiation in - beam
What is the dose?
Amount of energy deposited in subject (NB absorbed, equivalent and effective
How are X-rays produced?
By the deceleration of fast moving charged particles
When are elections decelerated?
When they hit a tungsten target
What are the two processes of X-ray production?
Bremsstrahlung und characteristic radiation
What is bremsstrahlung?
Braking radiation (100% for a lot of diagnostic)
Generally the predominant process - up to 90% of total
( X-ray production in a diagnostic beam - no characteristic emitted below 70hv
