All of the following are true of K-edge filters EXCEPT
A)They are also called compound filters.
B)Copper and aluminum are the materials of choice.
C)They rely on photoelectric interactions and the production of characteristic radiation.
D)The x-ray beam traverses aluminum first, followed by the copper layer.

Question

Quizplus · Accepted Answer

K-edge filters, also known as compound filters, utilize materials like copper and aluminum because these materials have K-edges that are effective in filtering out low-energy photons through photoelectric interactions and the production of characteristic radiation. The correct sequence for the x-ray beam in a compound filter is to first pass through the copper layer and then the aluminum layer, not the other way around as stated in option D.
