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

The single most effective way to reduce the production of scatter is:
 
 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.

Before a vaccine is licensed in the USA, the Food and Drug Administration (FDA) reviews it for safety and effectiveness. The CDC then reviews all studies again, as well as the American Academy of Pediatrics and the American Academy of Family Physicians. Every lot of vaccine is tested before administration to the public, and the FDA regularly inspects vaccine manufacturers' facilities.
