The inverse square law states that the intensity of radiation is inversely proportional to the square of the distance from the source of radiation. This means that as you double the distance from the source, the intensity of the radiation exposure decreases to one-fourth of its original value. Therefore, if you were to plot the exposure against distance, you would observe a significant decrease as the distance increases.

This law is particularly important in radiography and other practices involving radiation, as it highlights the necessity of maintaining appropriate distances from X-ray sources to minimize exposure to personnel and patients. Understanding this relationship is crucial for safety protocols and shielding considerations in radiographic practices.
