Alara is a concept in the field of radiation safety that stands for "As Low As Reasonably Achievable." It is a principle aimed at minimizing exposure to ionizing radiation for both workers and the public. This involves implementing measures and practices that reduce radiation levels while considering economic and social factors. The ALARA principle is widely applied in industries such as nuclear power, medical imaging, and research. By following ALARA guidelines, organizations strive to protect individuals from unnecessary radiation exposure while still allowing for necessary activities that require the use of radiation.
