Question

Which of the following does NOT affect the quantity of x-rays that completely penetrates the patient?

1. the distance that the x-ray photons must travel on their course through the body
2. the molecular composition of the tissues through which the x-ray photons pass
3. the type of detector material used

Answer 1

The type of detector material used does not affect the quantity of x-rays that completely penetrate the patient. However, the distance that the x-ray photons travel through the body and the molecular composition of the tissues they pass through do affect this quantity.

Step-by-step explanation:

The quantity of x-rays that completely penetrates the patient is not affected by the type of detector material used.

The distance that the x-ray photons travel on their course through the body and the molecular composition of the tissues through which the x-ray photons pass both have an impact on the quantity of x-rays that completely penetrates the patient.
