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

The ALARA principle, which stands for "As Low As Reasonably Achievable," is fundamental in radiation safety practices. Its main purpose is to minimize radiation exposure to individuals by implementing measures that reduce exposure to levels that are both low and achievable without compromising the desired outcomes. This principle acknowledges that while some radiation exposure is unavoidable, every effort should be made to limit unnecessary exposure through careful planning, use of protective equipment, and adherence to safety protocols. By focusing on minimizing exposure, the ALARA principle helps to protect both workers and the public from potential harmful effects of radiation.
