ALARP Explored

Lookup NU author(s): Felix Redmill



This paper explores the ALARP Principle. It explains its tenets, presents its history, examines its practical application, and discusses the concepts which underpin it and to which it is related. Whereas the paper's narrative is continuous, each chapter covers its topic fully, is largely self-contained, and may be read in isolation - except that Chapter 4 is a necessary preliminary to Chapter 5. Chapter 1 introduces the subject of risk, the variability of its perception between individuals, and the nature and need of risk-tolerability decisions. Chapter 2 introduces and explains the ALARP Principle, and Chapter 3 recounts its development from a legal perspective. Chapter 4 derives the preparatory processes essential to the Principle's application, and Chapter 5 describes the processes necessary for its central purpose - the making of risk-tolerability decisions. Section 6 offers a discussion of the main risk-based concepts on which the Principle depends and with which it interacts. Finally, Chapter 7 draws conclusions and discusses the relationship between the Principle and the law of the land.
