Which of the following statements describes the relationship between source-to-image distance (SID) and receptor exposure?

Which source-to-image distance will demonstrate the highest receptor exposure?

A radiographic technique chart recommends 4 milliampere-seconds (mAs) and 68 kilovoltage peak (kVp) at 72 inches for a certain procedure. How will the receptor exposure be affected if the radiograph is performed using the recommended exposure technique but at 60 inches?

Performing a routine chest radiograph in the anterior-posterior (AP) projection will

Scattered radiation that hits the image receptor produces:

The area of the x-ray beam projected towards the patient is described as the:

The source of x-ray emission within an x-ray tube is called the:

The Line-Focus Principle describes the geometric relationship between which of the following factors within an x-ray tube?

A radiograph is to be made with a 40 inch source-to-image distance (SID) using 12 miliampere-seconds (mAs). If the SID is increased to 72 inches, how could the mAs be changed to maintain the same receptor exposure??

If an optimal radiograph is acquired at 72 inches with an air kerma of 4 mGy, what will the air kerma be if the distance is reduced to 40 inches?
