If the x-ray tube is moved closer to the image receptor, the radiation intensity at the IR:

A radiograph is made with a 36-inch source-to-image distance (SID) resulting in a receptor exposure of 0.01 milligray (mGy). What will the receptor exposure be if the SID is changed to 72 inches?

A radiographer has the choice of multiple radiographic systems, each using a different actual focal spot size. Which system should be used if maximum heat dissipation is required?

To calculate SOD:

A radiograph is acquired using a source-to-image distance (SID) of 40 inches. If the radiograph is repeated using the same exposure factors, but the SID increases to 60 inches, the receptor exposure will:

An x-ray source is producing an entrance skin exposure of 3.1 mSv per hour at 10 cm from the source. What is the entrance skin exposure at 15 cm from the source?

The distance between the anatomy being imaged and the focal spot is called:

The difference between two adjacent densities is

Which one of these is performed first when calculating the exposure maintenance formula?
