Which of the following is a method to limit exposure to radiation?

Utilizing personal protective equipment (PPE) is a critical method to limit exposure to radiation. PPE includes specialized clothing and gear designed to shield the body from harmful radiation while performing duties in environments where radiation is present. This equipment can include lead aprons, gloves, face shields, and other barriers that reduce the amount of radiation that can reach the skin and internal organs.

By effectively using PPE, workers can continue performing necessary tasks while ensuring their safety, thereby minimizing potential health risks associated with radiation exposure. It plays a vital role in a comprehensive radiation safety program, alongside other strategies like time limitation and distance from radiation sources.

The other options, while related to radiation safety, do not effectively limit exposure. For instance, increasing the time spent near a source actually increases exposure risk, and avoiding training sessions does not engage any safety measures or awareness that could help reduce risks. Consolidating radioactive waste is an important safety practice but does not directly limit personal exposure as wearing PPE does.
