Which term means exposure to radiation energy?

• A. Acute Radiation Syndrome
• B. Irradiation
• C. Contamination
• D. Toxicology

Answer: (B)

Exposure to radiation energy is called irradiation. It describes the process of radiation delivering energy to a material or tissue as it passes through or interacts with it, whether from external sources like X-rays or gamma rays. This is the term used for being subjected to radiation itself. Contamination refers to radioactive material being present on surfaces or on the body, which may cause exposure if it decays or is ingested, but it is not the act of exposure. Acute Radiation Syndrome is the clinical illness that can follow a high-dose exposure, not the exposure itself. Toxicology is the broader study of how toxic substances affect living beings, not a term for radiation exposure.
