Radioactive sources: use, safety and security

Abstract

Purpose: this publication aims to familiarise you with the use, safety and security of sealed radioactive sources. It describes the types of industry where these sources might be found and outlines a radioactive source categorisation scheme that can tell you how dangerous a source is. This information is intended to raise awareness that radioactive sources are widely used and must be appropriately secured and safely used to prevent harm, whether unintentionally or maliciously.
