What principle of radiation safety emphasizes minimizing exposure to radiation whenever possible?

The principle of radiation safety that emphasizes minimizing exposure to radiation whenever possible is ALARA, which stands for "As Low As Reasonably Achievable." This principle is fundamental in radiation safety practices and states that efforts should be made to keep radiation exposure to individuals and the environment as low as is practical, taking into account social, technical, and economic considerations.

ALARA focuses not only on limiting exposure but also on adopting measures that ensure that radiation doses are controlled and monitored efficiently. By integrating this principle, facilities that work with radiation can enhance safety protocols, conduct risk assessments, and implement engineering controls to reduce radiation levels. This proactive approach ensures a culture of safety and reinforces the importance of careful management of radiation use in various applications, including medical imaging and therapeutic interventions.
