What term reflects biological tissue damage from exposure to differing types of radiation?

• A. Chemical Injury
• B. Radiation Injury
• C. Thermal Burn
• D. Mechanical Trauma

Answer: (B)

Radiation injury describes biological tissue damage caused by exposure to ionizing radiation. Ionizing radiation can ionize molecules and generate free radicals, leading to cell death and tissue damage that may be localized (such as skin exposure) or systemic at higher doses (acute radiation syndrome). This term specifically covers injuries from radiation, unlike chemical injury (harm from toxic chemicals), thermal burn (damage from excessive heat), or mechanical trauma (injury from physical force).
