Electromagnetic Radiation Flashcards
1
Q
how does electromagnetic radiation travel?
A
electromagnetic radiation travels in straight lines
2
Q
what is the intensity of the x-ray beam
A
the total amount of energy passing through unit area in one second (also called energy fluence)
3
Q
what is the inverse square law?
A
the intensity of the beam is inversely proportional to the square of the distance from the source, ie: further away, lower intensity of radiation, less dose of radiation received
