What is the purpose of the ALARA principle?

The ALARA principle stands for "As Low As Reasonably Achievable." Its primary purpose is to minimize radiation exposure to patients, staff, and the public to the lowest possible levels while still achieving the necessary diagnostic or therapeutic results. This principle is fundamental in radiology and dental practices because it emphasizes the importance of taking all reasonable steps to reduce radiation doses, using appropriate technologies, optimizing procedures, and ensuring that protective measures are in place.

By adhering to the ALARA principle, healthcare professionals can effectively balance the need for radiographic examinations against the risks associated with radiation exposure. This involves using the lowest dose of radiation needed for a specific imaging task, implementing shielding options, and continuously evaluating practices to identify opportunities for dose reduction without compromising the quality of care. The ALARA principle also encourages ongoing education and training for professionals, ensuring they remain aware of the best practices for radiation safety.
