Inverse square law Flashcards
1
Q
What is beam intensity?
A
Beam intensity is the amount of energy in the beam
Intensity is proportional to beam current
INTENSITY ∝ mA
2
Q
Inverse Square Law is what?
A
The relationship between intensity and distance is called the Inverse Square Law (ISL)
The greater the distance from the source of radiation, the lower the intensity of the beam
3
Q
How do you work out inverse square law
A
I = k/d² I = Intensity k = constant d = distance
