What is the term for materials that emit radiation?

The term "radiological material" specifically refers to substances that emit radiation, which can be classified as ionizing radiation such as alpha particles, beta particles, gamma rays, or neutron radiation. These materials are important in various contexts, including medical applications, nuclear power, and certain industrial processes. Understanding radiological materials is crucial for HAZMAT responders as they must be equipped to manage incidents involving radiation exposure and contamination.

The other terms do not correctly describe materials that emit radiation. Chemical agents refer to toxic substances that cause harm through chemical reactions, while biological agents pertain to pathogens or toxins that affect living organisms. Pollutants are typically substances that cause environmental harm, but they may not emit radiation. Hence, among the choices provided, "radiological material" is the most accurate and relevant term for materials that emit radiation.
