Share:

The 1978 American National Standard specifies techniques and instrumentation for measuring potentially hazardous electromagnetic fields from 1 MHz to 100 GHz in both near and far field conditions.

Plain English Summary

Summary written for general audiences

Instruments should read average power density, mean squared electric field strength, mean squared magnetic field strength, or energy density. Calibration methods include free-space standard field, guided wave methods, and standard probe method.
