Answer to Question 1

decreased density

Rationale: Milliamperage-seconds, mAs, contributes to the overall blackness of the image. It represents the quantity of radiation produced.

Answer to Question 2

90 degrees to the patient

Rationale: The technologist should stand 90 degrees to the patient or scattering object to minimize their exposure dose. Standing at the foot or the head of the bed will result in the greatest exposure.
