Which of these statements about Safety Code 6 is NOT correct?
B
Answer
Regulations and administration
Type
A
Safety Code 6 sets limits for induced currents, electrical field strength and magnetic field strength from electromagnetic radiation
B
Safety Code 6 sets limits in terms of power levels fed into antennas
C
Safety Code 6 sets limits for allowable rates at which RF energy is absorbed in the body (specific absorption rate)
D
Safety Code 6 sets limits for contact currents that could be drawn from ungrounded or poorly grounded objects
Answer Notes
Health Canada's Safety Code 6 specifies the maximum limits of human exposure to radiofrequency (RF) electromagnetic fields. It focuses on the actual RF energy present in the environment where humans might be exposed, regulating electric field strength, magnetic field strength, contact currents, and specific absorption rate (SAR).
Safety Code 6 does not set limits based on the power level fed into the antenna. The power fed into the antenna is only one variable in calculating exposure; antenna gain, frequency, and distance to the antenna all determine the actual field strength that reaches a person. Therefore, claiming it regulates the power fed into the antenna is the incorrect statement.
