What does the term "ALARA" stand for in radiation protection?

The term "ALARA" stands for "As Low As Reasonably Achievable," which is a fundamental principle in radiation protection. This approach emphasizes minimizing radiation exposure to individuals, while still accomplishing necessary tasks or objectives. The core idea is to ensure that all levels of radiation exposure are kept as low as possible, taking into account social, technical, and economic factors.

ALARA is used in various fields, including healthcare, nuclear power, and research, to safeguard workers, patients, and the public from unnecessary radiation exposure. It involves practices such as proper shielding, limiting time spent in areas with radiation, and maintaining adequate distances from radiation sources.

Understanding this principle is crucial for professionals working with radiation, as it guides decision-making processes and helps establish guidelines and standard operating procedures designed to enhance safety and minimize risk.
