Which of the following is a recommended practice for reducing radiation exposure?

Increasing distance from the radiation source is a fundamental practice for reducing radiation exposure, grounded in the principles of radiation safety. This principle is often articulated by the inverse square law, which states that the intensity of radiation decreases significantly as one moves further away from the source. Specifically, doubling the distance from a radiation source can reduce exposure by a factor of four. This makes distance an effective strategy for minimizing potential health risks associated with radiation.

While other practices may have some relevance in specific contexts, maintaining a safe distance is universally recognized as a straightforward and highly effective method to limit exposure levels. It is crucial for individuals working in radiation environments to apply this principle consistently for their safety and the safety of their colleagues.
