In this article: The concept of ALARP How is the ALARP principle implemented in practice? Benefits and challenges Practical Guidance Conclusion The concept of ALARP  The As Low As Reasonably Practicable (ALARP) or As Low As Reasonably Achievable (ALARA)  principle is a cornerstone of risk management and is a tool used to support decisions in the risk management process and illustrate risk tolerability. The principle means that a risk should be reduced to a level that is as lo
