HF Tx Po=90W PEP on 7.1MHz, 15m RG-58C/U to a ground mounted quarter wave vertical, VSWR =1.5, SSB voice modulation.

VHF Tx Po=50 PEP on 146MHz, 50m LDF4-50 to a Yagi, VSWR =1.25, FM voice modulation.

GSM 850 BTS Tx Po=25W PEP on 850MHz, 0dB feed loss, 15dBi panel, CW (conservative model).

This calculator implements the methods and radiation thresholds described in:

The ACA document "Human Exposure to Radiofrequency Electromagnetic Energy - Information for licensees or operators of radiocommunications transmitters: Evaluation of compliance with the ACA standard - September 2000";

The FCC document "Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields" - OET Report 65 Edition 97-01;

ICNIRP document "GUIDELINES FOR LIMITING EXPOSURE TO TIME-VARYING ELECTRIC, MAGNETIC, AND ELECTROMAGNETIC FIELDS (up to 300 GHz)" April 1998.

ARPANSA draft Radiation Protection Standard - Maximum exposure levels to radiofrequency fields - 3kHz to 300GHz (assuming plane wave conditions).
