Exposure to Non-ionizing Radiation does what to the human body?

• A. Permanently changes cells
• B. Does not permanently change cells
• C. Alters DNA structure
• D. Weakens immune system

Answer: (B)

Exposure to non-ionizing radiation does not result in permanent changes to cells. Non-ionizing radiation, which includes forms such as radio waves, microwaves, and visible light, primarily causes thermal effects by heating biological tissue rather than damaging the cellular structure or DNA. Unlike ionizing radiation, which has enough energy to remove tightly bound electrons from atoms and can cause chemical changes in cells, non-ionizing radiation is generally considered safer, as it does not lead to irreversible mutations or cellular damage. The absence of permanent cellular changes from non-ionizing radiation is significant for understanding safety standards and regulatory guidelines for exposure. It helps in assessing risk levels for workers and individuals who might be exposed to wireless communications and other technologies relying on non-ionizing radiation.
