In terms of operator exposure, what does the method of distance refer to?

The method of distance in the context of operator exposure primarily emphasizes the importance of maximizing distance from the radiation source during an exposure. This principle is rooted in the concept of radiation protection, as the intensity of radiation decreases with increasing distance due to the inverse square law. Essentially, this law states that as you move away from a point source of radiation, the exposure level decreases proportionally to the square of the distance.

By maximizing the distance between the operator and the x-ray source, the operator significantly reduces their own exposure to radiation. Therefore, this method is a key safety practice in radiography, ensuring that operators remain within safe limits while performing their duties.
