Which statement about non-ionizing radiation is presented in the material?

• A. It causes ionization of atoms
• B. It does not interact with matter
• C. It is primarily used to sterilize equipment
• D. It causes chemical changes at the atomic level

Answer: (D)

Non-ionizing radiation delivers energy to matter without knocking electrons off atoms. That energy can be absorbed by molecules, causing them to vibrate, rotate, or reach excited states. When molecules absorb this energy, chemical bonds can change or break, leading to chemical changes at the molecular level—even though atoms aren’t ionized. That’s why the statement about non-ionizing radiation causing chemical changes is the best fit. The other ideas don’t line up with how non-ionizing radiation behaves: it does interact with matter through absorption and heating, it does not ionize atoms, and sterilization is typically accomplished with ionizing radiation or other methods; while some non-ionizing forms (like UV-C) can disinfect surfaces, they are not generally described as the primary method for sterilizing equipment in HazMat contexts.
