What is the principle of ALARA in radiation protection?

The principle of ALARA, which stands for "As Low As Reasonably Achievable," is a fundamental concept in radiation protection aimed at minimizing exposure to ionizing radiation. This principle emphasizes that exposure to radiation should be kept to the lowest possible levels, taking into account economic and socio-political factors. The goal is to reduce the dose received by workers and the public without compromising the benefits gained from the use of radiation in various applications, such as medical imaging and industrial radiography.

Implementing ALARA requires a proactive approach to identifying potential radiation sources and utilizing strategies to limit exposure. This may include engineering controls, administrative policies, training, and personal protective equipment. By actively striving to maintain radiation levels as low as possible through these measures, organizations can protect the health and safety of individuals while still conducting necessary radiographic activities.
