[DyllonKazuo]

Total filtration requirements for units operating below 50 kVp are:
 
 2.5 mm Al
  1.5 mm Al
  0.50 mm Al
  3.0 mm Al

Question 2

A form of beam restriction that when activated by a loaded cassette in the Bucky automatically adjusts the collimated light field is:
 
 extension cones
  manual collimation
  Positive Beam Limitation
  aperture diaphragms

Answer to Question 1

0.50 mm Al

Rationale: Total filtration requirements for tubes operating below 50 kVp is 0.5 mm Al, 1.5 mm Al for tubes operating between 50-70 kVp, and 2.5 mm Al for tubes operating above 70 kVp.

Answer to Question 2

Positive Beam Limitation

Rationale: Positive Beam Limitation (PBL) is a form of collimation that automatically happens when the image receptor is placed within the Bucky. When activated, the light field automatically adjusts to the field size and orientation.
