How can exposure to a large amount of RF energy affect body tissue?

Radio frequency (RF) energy is a form of non-ionizing radiation. Unlike ionizing radiation (such as X-rays), RF energy does not carry enough energy to strip electrons from atoms or directly mutate DNA. Instead, the primary biological effect of high-level RF exposure is localized heating. When body tissues absorb RF energy, the molecules vibrate rapidly, generating heat much like how a microwave oven warms food. It does not cause paralysis, lower blood pressure, or restrict blood flow. Avoiding situations where the body cannot dissipate this excess thermal energy is a fundamental rule of RF safety.
