Annex Antenna radiation limits - health and safety Antenna radiation The transmit antenna must be installed such that the resultant radiated field strength is below national limits. The safe distance must be calculated for each installation.
E = electric field strength (V/m) B = magnetic flux density (T) η = impedance of free space (377 Ω in far field) μ0 = permeability of free space (4x10-7 π) (H/m). Based on this formula and using a 2 dBi antenna, For occupational workers (RF and microwave): The predicted safe distance from the centre of the radiation would be approximately 1.4 m for values as shown in the table. For persons not classed as occupational workers, and including the general public: The minimum safe distance would be 3.
Canada The RF power density limits according to Health Canada Safety Code 6, are shown in the table below: Frequency MHz Occupational level W/m2 General population level W/m2 112.000 6.83 1.29 118.000 7.01 1.29 127.500 7.28 1.29 136.975 7.55 1.29 155.975 8.06 1.29 225.000 9.68 1.29 300.000 11.18 1.29 399.975 12.90 1.57 The general equation for Occupational level: RF power density = 0.6455 f 0.5 W/m2 where, f = frequency in MHz.
United States of America The RF power density limits according to FCC directive CFR 47 Part 2.109, are shown in the table below: Frequency MHz Occupational level W/m2 General population level W/m2 112.000 - 300.000 10.0 2.00 399.975 13.34 1.57 The general equations for Occupational level: For 100 to 300 MHz, RF power density = 10 W/m2, and For 300 to 400 MHz, RF power density = f /30 W/m2 where, f = frequency in MHz.
