What is the purpose of employing the ALARA principle in radiation safety?

The ALARA principle stands for "As Low As Reasonably Achievable." Its core purpose in radiation safety is to minimize exposure to ionizing radiation and to limit the release of radioactive materials into the environment. This goal is achieved by implementing measures to reduce exposure through engineering controls, administrative procedures, and appropriate protective equipment, while factoring in economic and societal considerations.

The emphasis on minimizing exposure aligns with the understanding that any amount of radiation could pose potential health risks. By striving to keep radiation exposure as low as reasonably achievable, individuals and organizations can ensure greater safety for workers, patients, and the public. This principle is a cornerstone of radiation protection practices, fostering a culture of safety and responsibility in environments where radiation is used or encountered.
