What occurs when the amperage of the master control unit is increased?

  1. Radiation produced decreases

  2. Radiation produced increases

  3. Radiation produced stays the same

  4. None of the above

The correct answer is: Radiation produced increases

Increasing the amperage in the master control unit directly relates to the amount of current flowing through the x-ray tube. As the amperage increases, more electrons are available to produce x-rays, leading to an increase in the quantity of radiation produced. This is grounded in the principle that higher amperage allows for a greater number of x-rays to be generated during exposure, resulting in a higher dose of radiation being emitted. Therefore, it is accurate to say that as the amperage is increased, so too are the levels of radiation produced by the x-ray system.
