What is the purpose of the Safety Code 6?
-
Correct AnswerIt gives RF exposure limits for the human body
-
It lists all RF frequency allocations for interference protection
-
It sets transmitter power limits for interference protection
-
It sets antenna height limits for aircraft protection
Tags: none
According to Safety Code 6, what frequencies cause us the greatest risk from RF energy?
-
300 to 3000 MHz
-
Correct Answer30 to 300 MHz
-
Above 1500 MHz
-
3 to 30 MHz
Tags: none
Why is the limit of exposure to RF the lowest in the frequency range of 30 MHz to 300 MHz, according to Safety Code 6?
-
There are more transmitters operating in this range
-
There are fewer transmitters operating in this range
-
Most transmissions in this range are for a longer time
-
Correct AnswerThe human body absorbs RF energy the most in this range

Correct Answernot specified — the exemption for portable equipment was withdrawn in 1999
-
25 watts
-
125 milliwatts

-
Maximum exposure levels of RF fields to the general population, in the frequency range 10 to 300 MHz, is 28 VRMS/metre (E-field)
-
Permissible exposure levels of RF fields increases as frequency is increased above 300 MHz
-
Permissible exposure levels of RF fields increases as frequency is decreased below 10 MHz
-
Correct AnswerPermissible exposure levels of RF fields decreases as frequency is decreased below 10 MHz
Tags: none
The permissible exposure levels of RF fields:

decreases, as frequency is decreased below 10 MHz
-
Correct Answerincreases, as frequency is increased above 300 MHz
-
increases, as frequency is increased from 10 MHz to 300 MHz
-
decreases, as frequency is increased above 300 MHz
