    B-001-24-01
    What organization has published safety guidelines for the maximum limits of RF energy near the human body?
    Canadian Standards Association
    Environment Canada
    Transport Canada
    Health Canada

    B-001-24-02
    What is the purpose of the Safety Code 6?
    It 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

    B-001-24-03
    According to Safety Code 6, what frequencies cause us the greatest risk from RF energy?
    300 to 3000 MHz
    30 to 300 MHz
    Above 1500 MHz
    3 to 30 MHz

    B-001-24-04
    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
    The human body absorbs RF energy the most in this range

    B-001-24-05
    According to Safety Code 6, what is the maximum safe power output to the antenna of a hand-held VHF or UHF radio?
    10 watts
    not specified the exemption for portable equipment was withdrawn in 1999
    25 watts
    125 milliwatts

    B-001-24-06
    Which of the following statements is not correct?
    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
    Permissible exposure levels of RF fields decreases as frequency is decreased below 10 MHz

    B-001-24-07
    The permissible exposure levels of RF fields:
    decreases, as frequency is decreased below 10 MHz
    increases, 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

    B-001-24-08
    Which statement is not correct:
    maximum exposure level of RF fields for general population, in the range 10 to 300 MHz, is 28 V RMS per metre (Efield)
    portable transmitters, operating below 1 GHz with a power output up to 7 watts, are excluded from Safety Code 6 requirements
    maximum exposure level of RF fields for general population, in the range 30 to 300 Mhz, is .073 A RMS per metre (Hfield)
    the exemption of portable transmitters, operating below 1 GHz with a power output up to 7 watts was removed from Safety Code 6 in 1999

    B-001-24-09
    Which statement is correct?
    Safety Code 6 regulates the operation of receivers only
    the operation of portable transmitting equipment is of no concern in Safety Code 6
    portable transmitters, operating below 1 GHz, with an output power equal to, or less than 7 watts, are exempt from the requirements of Safety Code 6
    the exemption for portable transmitters was eliminated in Safety Code 6 in 1999
