Which practice can reduce exposure to radiation in a medical setting?

Using shielding and maintaining distance from radiation sources is a well-established principle in radiation safety known as the ALARA (As Low As Reasonably Achievable) approach. Shielding involves the use of barriers to absorb or deflect radiation, which significantly reduces exposure. For instance, lead aprons or walls containing lead can effectively block harmful radiation from reaching personnel or patients.

Furthermore, maintaining distance from the source of radiation is another crucial tactic. The intensity of radiation decreases with distance due to the inverse square law, which states that as one moves away from a radiation source, the radiation exposure decreases exponentially. By maximizing the distance from radiation sources during procedures, medical staff can significantly lower their exposure levels.

The combination of using appropriate shielding materials and increasing the distance from radiation sources creates a strong defense against unnecessary radiation exposure for both healthcare workers and patients. This practice is essential for ensuring safety in a medical environment where radiation is utilized.
