ISO 361:1975

Overview

is an international standard developed by the International Organization for Standardization (ISO). It establishes the design, proportions, and application guidelines for the universal ionizing radiation warning symbol. This symbol is essential for safety in environments where there is actual or potential exposure to ionizing radiation, such as gamma rays, X-rays, alpha and beta particles, high-speed electrons, neutrons, and protons. The standard ensures consistency in communicating radiation hazards across various sectors and regions.
