What is the approximate range of potential difference used in diagnostic radiography?

In diagnostic radiography, the potential difference, or kilovoltage (kV), plays a critical role in determining the quality and penetrating ability of the X-rays produced. The correct range for diagnostic radiography typically falls between 50 to 120 kilovolts.

This range is optimal because it allows for sufficient energy to generate diagnostic images while minimizing patient exposure to radiation. At lower kilovoltages, the X-rays produced may not penetrate the tissues adequately, leading to poor image quality. Conversely, higher kilovoltages might produce excess radiation, which is unnecessary and potentially harmful.

In practical applications, using 50 to 120 kilovolts provides the balance needed for producing clear images of various body structures, making it suitable for a wide array of diagnostic procedures.
