What does ALARA stand for in radiation safety?

ALARA stands for "As Low As Reasonably Achievable." This principle is fundamental in radiation safety and emphasizes the importance of minimizing radiation exposure to workers, the public, and the environment to the lowest possible levels. The concept is based on the understanding that any exposure to radiation carries some level of risk, and therefore, all reasonable measures should be implemented to reduce exposure as much as possible, without compromising operational safety and efficiency.

The ALARA principle involves several strategies, including incorporating engineering controls, administrative practices, and personal protective equipment. It is essential for ensuring that facilities and personnel manage radiation use responsibly, prioritizing safety while still allowing for necessary work to be completed. The focus on what is "reasonably achievable" recognizes that while it may not be possible to eliminate exposure entirely, significant reductions can often be made with careful planning and implementation.
