2025 DEQ Radiation Safety Complete Practice Test

Mitigating exposure to low-level radiation in the workplace is effectively achieved through increasing distance and utilizing barriers. This approach is based on the principles of radiation safety, which emphasize reducing exposure by maximizing the distance between individuals and the radiation source. This is because radiation intensity decreases significantly with distance. In addition, using physical barriers, such as lead shields or protective walls, can absorb or deflect radiation, further reducing exposure to personnel.

The other strategies listed, such as decreasing ventilation, working without protective gear, and limiting employee knowledge of risks, do not contribute to effective radiation safety and may instead increase the risk to worker health and safety. Adequate ventilation is important for maintaining air quality and is unrelated to radiation exposure directly. Working without protective gear exposes individuals to greater risks from radiation, and limiting knowledge prevents employees from taking informed actions to protect themselves, which is counterproductive to safety practices.
