Question

question 30 / 40 which statement describes the relationship between source - to - image distance (sid) and receptor exposure? receptor exposure is inversely proportional to the square of the sid receptor exposure is directly proportional to the square of the sid receptor exposure is inversely proportional to the sid receptor exposure is directly proportional to the sid

Explanation:

The inverse - square law in imaging states that the intensity of the radiation (which relates to receptor exposure) is inversely proportional to the square of the distance from the source. Here, the source - to - image distance (SID) is the distance from the source to the receptor. So, receptor exposure is inversely proportional to the square of the SID.

Answer:

Receptor exposure is inversely proportional to the square of the SID
