HIRF meaning in Electronics ?

A high-intensity radiated field (HIRF) is radio-frequency energy of a strength sufficient to adversely affect either a living organism or the performance of a device subjected to it. A microwave oven is an example of this principle put to controlled, safe use. Radio-frequency (RF) energy is non-ionizing electromagnetic radiation – its effects on tissue are through heating.Electronic components are affected via rectification of the RF and a corresponding shift in the bias points of the components in the field.

The U.S. Food and Drug Administration (FDA), and U.S. Federal Communications Commission (FCC) set limits for the amounts of RF energy exposure permitted in a standard work-day.
