The International Atomic Energy Agency (IAEA) published the Specific Safety Guide (SSG)-91, “Protection of Workers Against Exposure Due to Radon” in November 2024, providing recommendations for protecting workers from radon exposure in workplaces. Section 2 of SSG-91 introduces the framework to determine appropriate approaches for the protection. Sections 3 and 4 provide guidance on protecting workers in existing exposure situations and planned exposure situations, respectively. These sections also include recommendations for the protection, along with detailed explanations of the responsibilities and functions of the government, the regulatory body or other relevant authority, and employers. This paper provides an overview of SSG-91, summarizing key points from each chapter. Additionally, it discusses the background behind the development of SSG-91 and explains related developments in Japan.
