What does ALARA stand for in radiation safety?

The term "ALARA" stands for "As Low As Reasonably Achievable." This principle is fundamental in radiation safety and emphasizes the importance of minimizing radiation exposure to patients, staff, and the general public. The concept of ALARA encourages practices that reduce radiation doses while still achieving the desired outcomes in medical imaging and other radiation-related procedures. It involves a balance of social, technical, and economic factors to ensure that exposure is kept to the minimal level necessary for safety and efficacy.

In the context of radiation safety, implementing ALARA involves using appropriate shielding, distance, and exposure time strategies, as well as improving operational protocols and employing better technology. These measures collectively help maintain radiation exposure within safe limits without compromising diagnostic quality or therapeutic effectiveness. This understanding is crucial for professionals working in environments where radiation is present, as it directly relates to the safety and health of both patients and healthcare workers.
