Considering radiographs produced with the following factors, which statement is true?Radiograph ARadiograph B500 mA500 mA0.02 sec0.08 sec36-inch SID72-inch SID

When an air-gap technique is used, the amount of scatter reaching the image receptor is decreased because:

According to the inverse square law, when the distance between the x-ray source and the point of measurement (patient, worker, or receptor) increases, the beam quantity will:

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:

A satisfactory x-ray of the wrist is produced using a technique of 300 milliamperes (mA), 15 milliseconds, 50 kilovoltage peak (kVp), and a source-to-image distance (SID) of 40 inches. How should the mA be changed if the exposure time is decreased to 10 milliseconds?

The y-axis for all emission spectra represents the:

Consider a technologist exposed to a dose rate of 3 mGy/hour at a distance of 7 feet from the x-ray source. What is the total absorbed dose to the worker during a 1 hour period if they step back to 11 feet from the source?

Adding filtration in the path of the beam results in the x-ray emission spectrum:

The distance at which a focused grid can be used is most closely related to the:

If an x-ray beam has an intensity of 1.2 mGy at 60 inches, what is the intensity of the beam 40 inches?
