What
factors must you consider if your repeater station antenna will
be
located at a site that is occupied by antennas for transmitters in
other
services?
A. Your radiated signal must be considered as
part of the total RF
radiation
from the site when determining RF radiation exposure levels
B. Each individual transmitting station at a
multiple transmitter
site
must meet the RF radiation exposure levels
C. Each station at a multiple-transmitter site
may add no more than
1% of
the maximum permissible exposure (MPE) for that site
D. Amateur stations are categorically excluded
from RF radiation
exposure
evaluation at multiple-transmitter sites

B. 10 minutes
C. 15 minutes
D. 30 minutes

*Modified
A for new rules
How
does an Amateur Radio operator demonstrate that he or she has read
and
understood the FCC rules about RF-radiation exposure?
A. By indicating his or her understanding of
this requirement on an
amateur
license application form at the time of application
B. By posting a copy of Part 97 at the station
C. By completing an FCC Environmental
Assessment Form
D. By completing an FCC Environmental Impact
Statement
T0B07
@N0C01
What
amateur stations must comply with the requirements for RF
radiation
exposure spelled out in Part 97?
A. Stations with antennas that exceed 10 dBi of
gain.
B. Stations that have a duty cycle greater than
50 percent.
C. Stations that run more than 50 watts peak
envelope power(PEP)
D. All amateur stations regardless of power
T0B08
@N0C02
Who is
responsible for ensuring that an amateur station complies with
FCC
Rules about RF radiation exposure?
A. The Federal Communications Commission
B. The Environmental Protection Agency
C. The licensee of the amateur station
D. The Food and Drug Administration
T0B09
@T0B05
Why do
exposure limits vary with frequency?
A. Lower-frequency RF fields have more energy
than higher-frequency
fields
B. Lower-frequency RF fields penetrate deeper
into the body than
higher-frequency
fields
C. The body's ability to absorb RF energy
varies with frequency
D. It is impossible to measure specific
absorption rates at some
frequencies
T0B10
@T0B06
Why is
the concept of "duty cycle" one factor used to determine safe
RF
radiation exposure levels?
A. It takes into account the amount of time the
transmitter is
operating
at full power during a single transmission
B. It takes into account
the transmitter power supply rating
C. It takes into account
the antenna feed line loss
D. It takes into account the thermal effects of
the final amplifier
T0B11
@T0B11
From an
RF safety standpoint, what impact does the duty cycle have on
the
minimum safe distance separating an antenna and the neighboring
environment?
A. The lower the duty
cycle, the shorter the compliance distance
B. The compliance
distance is increased with an increase in the duty
cycle
C. Lower duty cycles subject the environment to
lower radio-frequency
radiation
cycles
D. All of these answers are correct
