Beam attenuation is defined as:
 
 scatter production
  strengthening of the beam as it passes through tissues
  the effects of absorption qualities upon tissues and radiographic appearances
  the path of the x-ray beam

Question 2

 increase filtration
  collimate
  use of a grid
  increase screen speed

Answer to Question 1

the effects of absorption qualities upon tissues and radiographic appearances

Rationale: Tissues of different atomic numbers will either absorb the beam or allow the beam to pass easily through. Tissues with high atomic number such as bone will absorb most of the beam, resulting in white image components. Tissues easily penetrated will appear darker.

Answer to Question 2

collimate

Rationale: Scatter radiation occurs during interaction with patient tissue. The most effective means to decrease scatter production is through beam restriction.
