What does the acronym ALARA stand for in radiation safety?

The acronym ALARA stands for "As Low As Reasonably Achievable." This principle is foundational in radiation safety and emphasizes the importance of minimizing exposure to radiation risk while also considering economic and social factors. The intent of the ALARA approach is to ensure that radiation doses are kept to the lowest levels possible, taking into account all circumstances, which helps in protecting both workers and the public from unnecessary radiation exposure.

In practical terms, this involves using safety measures, monitoring, and appropriate shielding, as well as implementing processes that reduce the time spent near radioactive materials or radiation sources. The principle acknowledges that while it might not be feasible to eliminate all exposure, efforts must be made to reduce it to an acceptable level that is reasonable based on the current understanding of radiation effects and safety practices.
