The dose or energy absorbed by an irradiated object depends on which of the following settings?

The dose or energy absorbed by an irradiated object is primarily influenced by kilovolt and milliampere settings. Kilovoltage (kV) directly affects the energy and penetrating power of the radiation produced during the irradiation process. Higher kilovolt settings result in more energetic radiation, which can penetrate deeper into objects and lead to a greater dose.

The milliampere setting determines the current flowing through the x-ray tube, which influences the quantity or intensity of the radiation produced. A higher milliampere setting increases the number of photons generated, allowing for a higher dose to be delivered within a given exposure time.

Together, kilovolt and milliampere settings play a crucial role in controlling both the quality and quantity of radiation, ultimately affecting the energy absorbed by the object being irradiated. Understanding these parameters is essential for practitioners to optimize radiation therapy and imaging techniques while ensuring safety protocols are maintained.
