RF Safety Assistant

RF Safety Assistant by EME Safety, LLC is a field companion for RF/EME safety work. Estimate radio frequency power density near antennas, check results against regulatory limits and review the fundamentals of RF exposure, all in one place. CALCULATORS - Wire / whip antennas: FCC cylindrical model for dipole and monopole antennas (typically below 1 GHz). - Aperture antennas: near-field and far-field power density for microwave and dish antennas (above 1 GHz). - Phased array antennas: near-field and far-field models. - Results in W/m² and mW/cm², with a compliance check against the selected standard (FCC, ICNIRP, IEEE or Safety Code 6) and a step-by-step calculation breakdown. - Field level plots of power density versus distance. - Save each calculation as a PDF report and share it. EMF FIELD CONVERTER Convert between electric field strength (V/m), magnetic field strength (A/m) and power density (W/m²) using free-space impedance. RF SAFETY INFORMATION Plain-language overview of RF radiation, biological effects, exposure limits and standards, controlled vs. uncontrolled environments, power density and field strength, and near field vs. far field. RFSO TRAINING Overview of the Radio Frequency Safety Officer (RFSO) course topics from EME Safety, LLC. STANDARDS AND REFERENCES Curated links to FCC OET Bulletin 65, ICNIRP guidelines, IEEE C95.1 and Health Canada Safety Code 6 / ISED RSS-102. Available in English, French and Spanish. No account required. Calculations are estimates based on published models and are intended for planning and education. They do not replace an on-site survey with calibrated equipment or the judgment of a qualified RF safety professional.
