The amount of radiation used to generate

Describe exposure image is too dark, underexposure is
when the image is too light.
Think of toast ^^.
Describe scatter The bouncing of the x-rays off of tissue.
Scatter can cause exposure to the
radiographer and lead to exposure
outside the collimated areas.
