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

The term "ALARA" stands for "As Low As Reasonably Achievable," which emphasizes the importance of minimizing radiation exposure to workers and the public. This principle is a cornerstone of radiation safety practices and is based on the idea that all exposures to radiation should be kept as low as is reasonably possible, taking into account economic and social factors.

Implementing the ALARA principle involves assessing potential exposure scenarios, using appropriate engineering controls, protective equipment, and operational policies to limit exposure. It encourages continuous improvement in radiation protection practices, ensuring that every reasonable effort is made to reduce dose levels below regulatory limits.

This framework is essential for maintaining safety in environments where radiation is present, ensuring both health and safety while allowing for necessary work with radioactive materials. The focus on reasonableness also acknowledges that while it is impossible to eliminate all exposure, practical steps can be taken to minimize risks effectively.
