question 28 / 40
when the distance from the x - ray source increases, the beam intensity will:
increase
decrease
remain the same

Explanation:

The intensity of an x - ray beam follows the inverse - square law. According to this law, the intensity of a radiation beam is inversely proportional to the square of the distance from the source. So, as the distance from the x - ray source increases, the beam intensity decreases.

Answer:

Decrease
