What is the purpose of the ALARA principle?

The ALARA principle stands for "As Low As Reasonably Achievable," and its primary purpose is to minimize radiation exposure to both patients and healthcare staff. This principle is fundamental in radiological practices as it emphasizes safety and responsibility in the use of radiation in medical imaging and therapies. By focusing on keeping radiation doses as low as possible while still achieving the necessary diagnostic or therapeutic results, it helps to reduce the risk of adverse health effects, such as radiation-induced cancers or tissue damage, associated with unnecessary exposure.

In radiology and similar fields, adhering to the ALARA principle involves using the lowest effective radiation dose, optimizing imaging techniques, and implementing safeguards to protect personnel and patients. This commitment to minimizing radiation ensures that the benefits of diagnostic imaging outweigh the risks involved.
