ABSTRACT
During July 1976 a survey of the electromagnetic radiation emissions from the eN
Tower was made, to assess any possible health hazards to the general public and employees
working within the tower. Field intensity measurements were taken at all levels of occupancy
within the eN Tower, on the roofs of 5 downtown Toronto buildings, on 3 floors of the Bank
of Montreal Building, and at ground level of the Toronto Dominion Plaza. Measurements were
also taken along east, west and north radials from the eN Tower for distances up to 20 miles.
Unfortunately, at the time of the survey, not all the broadcast equipment had been
installed into the eN Tower and some of the stations were not operating at their fully licenced
power levels. However, the survey results indicate that microwave radiation exposure levels
are within currently accepted limits for both microwave radiation workers in the tower
and for the general public. There does not appear to be a health hazard from the electromagnetic radiations emitted from the eN Tower.

PREFACE
The Radiation Protection Bureau of the Environmental Health Directorate, Health
Protection Branch, conducts surveys to determine the radiation hazards to personnel in
establishments under Federal jurisdiction, by the authority of the Canada Labour Code.
The Ontario Ministry of Health is responsible for the health and safety of the general public
in areas coming under Provincial jurisdiction. The Federal Department of Communications
is responsible under the Radio Act for all technical matters relating to broadcasting and
microwave installations.
Since there were overlapping responsibilities with regard to the electromagnetic
transmissions from the CN Tower, it was decided that a joint survey be completed and that
the report be issued by the Department of National Health and Welfare in cooperation with
the Ontario Ministry of Health and Federal Department of Communications.
The following persons were involved in the CN Tower survey and the preparation
of this Report:

INTRODUCTION
The CN Tower, located in the downtown area of Toronto, rises 553 meters above
ground level.
Main features of the tower as shown in Appendix A, consist of
(i)
a concrete support column with services and reception area at ground level
(ii)
a pod at a height of 350 meters and containing 7 levels
(iii)
the central support column which continues through the roof of the pod and houses
the main elevator motors at a height of about 5 meters above the roof;
(i v)
(v)
a 91 meters high column supporting another public observation area; and
a 96 meters high spire containing the FM and TV antennae.
A map of the vicinity of the tower and details of its various levels are described
in Appendix C.
A number of tall buildings stand in its vicinity and several broadcasting transmitters
are located in this tower. Licensed effective radiated power (ERP) for various channels
and their present operating ERP levels are shown in Table 1.
The location of the tower, in a densely populated area combined with the high power
levels of its radio and television stations, have generated concern amongst the public. Enquiries
have been received by the Department of National Health and Welfare and the Ontario Ministry
of Health about possible adverse health effects resulting from exposure to the electromagnetic emissions from the tower.
In order to ascertain whether the broadcasting station employees and the public
were being excessively exposed to the tower emissions, it was decided that the electromagnetic fields should be measured at various locations within (i) the tower; (ii) highrise buildings
in the vicinity of the tower; and (iii) up to twenty miles away from the tower.
In July 1976 the Department of National Health and Welfare and the Ontario Ministry
of Health measured field intensities at all levels of occupancy in the CN Tower, on the
roofs of five buildings in downtown Toronto, on three floors of the Bank of Montreal Building,
and at the ground level of the Toronto Dominion Plaza. The Department of Communications
measured field intensities within twenty miles of the CN Tower. At the time of the survey,
all stations excepting channels 19 and 25 were operating on full power.
In 1977 channels 19 and 25 are expected to operate at full power of 1.08 and 2.14
megawatts respectively.
vii
- 2 Measurements
Measurements were recorded with the following instruments:
1. Rhode and Schwartz VHF-Field Strength Meter
Type HFV 203.6018.03 (25 MHz - 300 MHz)
2. Narda-Isotropic Radiation Monitor
Model 8315-A, Probe Model 8321 (0.3 - 18 GHz)
3. Raham Model 2 Radiation Hazard Monitor (10 MHz - 3GHz)
4. Instruments for Industry Model EFS-l Field Intensi ty Meter
(10 kHz - 200 MHz).
The Narda Monitor, although used as all indicator in some cases, was not appropriate
for all measurements since it does not respond below 300 MHz and so was only able to pick
up TV channels 19, 25 and 79.
The order of the recorded data in Appendix B for the measurements on the eN Tower
is, starting from the top of the tower:
(1)
Spire
(2)
Space Deck
(3)
Sky Pod Roof (above level 7 mechanical)
(4)
T.V. and F .M. Transmitters Levels 5 and 6
(5)
Restaurant Level 4
(6)
Upper Observation Deck Level 3
(7)
Lower Observation Deck Level 2
(8)
Microwave Radome Level 1
(9)
Ground Level
(10)
Buildings downtown
(11)
Ground level downtown (Toronto Dominion Plaza)
For areas (2) through (7) the notation "North" is Grid North for the city, and all
measurements thereafter are in a clockwise rotation.
Measurements were also carried out in the areas of the transmitting equipment
with special emphasis placed on the power combiners and dividers which feed the antennae.
- 3 Further measurements should be carried out when all the transmitters are operating
at full power, and the microwave installations on Levell of the tower are in operation.
SPIRE
This spire is a metal shell enclosed in a radome of non-conducting material which
alsu acts as a weather barrier. Portholes to the outer area allow observation of the antenna
elements.
Measurements were taken with all four instruments but due to the difficulty of zeroing
the first three instruments, only the INSTRUMENTS FOR INDUSTRY EFS-l readings are
listed.
These measurements were taken at the base of the spire and every second spider
(structural members inside the spire, as shown on page 3 of Appendix D) up to a maximum
of 36.6 m above the space deck. In the antenna spire the measurements are listed from
no. 1 to no. 7 at 36.6 m above the base in increments of approximately 6m.
SPACE DECK
Here the field strengths from the F .M. Stations were measured with the R & S Field
Intensity Meter. Other measurements were made with the Narda and Raham radiation monitors,
but the levels were less than the detection limit of the instruments (approximately 501-1 W/cm 2 ).
For each of the stations measured, six readings were taken starting at grid north. These
are shown in Appendix B.
SKY POD ROOF
To be consistent with the measurements made in the space deck, measurements
were performed in six locations maintaining a constant distance from the edge of the building
to the measurement site.
The measurements made for Ch 5 (77.25 MHz) are incomplete due to instrument
malfunction. However, due to the levels recorded for the three measurements taken, and
the patterns observed in the other measurements, it was felt that no further measurements
were necessary.
F.M. and T.V. TRANSMITTER ROOMS
Here measurements of power density were carried out around the transmitters and
transmission lines to the divider/combiners which feed the antennas. The values recorded
are shown in Appendix B.
- 4 The divider/combiners were the locations of maximum power, and the only points where
leakage values were observed to be within the range of sensitivity of the power density meters.
Field strength measurements were not taken in the F.M. and T.V. transmitter rooms since
levels would in all likelihood exceed the maximum capabilities of the field strength meter.
REST AURANT
The ten waiters' work stations were selected here as measurement sites because
of the access to mains power. This, combined with the complete coverage of the periphery
of the restaurant, made the work stations ideal locations. As before, the measurements
began at grid north and continued in a clockwise direction.
UPPER AND LOWER OBSER VA TION DECKS
Four measurement stations were selected for each of these two areas. The antenna
of the measuring instrument was positioned so it would not be affected by the metal window
frames of the upper observation deck or the metal hand rail and safety screen around the
perimeter of the lower observation deck.
MICROW A VE RADOME LEVEL 1
Measurements were made here with the broadband Raham model 2 monitor, even
though the antennae were not yet in use. This is one of the areas which should be resurveyed
when all equipment is operating at full rated power.
OUTDOOR TERRACE
The measurement sites for the outdoor terrace are shown in Appendix G. Number
1,2 and 3 indicate measurements taken alongside a walkway between the pool at the base
of the tower and the lunch bar. Measurement site no. 4 was on the upper level of the terrace
between the statue and the corner of the building. Number 5 was located in the main lobby
in front of a display of video monitors showing programming being transmitted from the
tower. The results in Appendix B are listed by position number.
SURROUNDING BUll_DINGS
Power density levels were determined at five buildings in downtown Toronto. This
was to determine electromagnetic radiation exposure levels to the general public. The measurements were made only on the roofs of the buildings with the exception of the tallest of the
fi ve, the Bank of Montreal building. Here the southwest corner, which is closest to the
tower, was selected as the si te for a series of measurements at fi fteen floor intervals, starting
at the roof and continuing down to the 30th floor.
- 5 Other Survey Data
1.
Department of Communications
A separate survey was completed by the Department of Communications, Ontario
Region and is described in their report "Field-Strength Measurements for Some Broadcast
Stations at the CN Tower". This survey was carried out under the Radio Act to determine
the field strengths of five (5) TV channels and three (3) FM broadcast stations. Measurements
were taken along east, west and north radials from the CN Tower. Field strength maxima
were observed at different locations for di fferent stations depending on the posi tion of the
antennae on the CN Tower and the shape of the field they radiate.
Field strengths are relatively low for each of the stations immediately underneath
the tower. Initially, they tend to rise away from the tower, attaining a peak and then rapidly
drop off. In each case, the measured value of the peak field strength was less than 600
millivolts per meter, which corresponds approximately to 0.01 microwatts per centimeters
squared.
2.
EMI Sound and Vision Equipment Limited
This company installed the broadcast equipment into the CN Tower, and carried
out a preliminary survey of radiation levels inside the antenna mast area. A summary of
the EMI survey is given in Appendix E.
EMI stated that the maximum recommended level for continuous working conditions,
by English standards was 200 volts per meter. All antennas were under power when the
tests were carried out. A person standing and working on the damper between channels
5 and 9 would have his head in from of the channel 9 panels. It was considered that this
area would produce 200 volts per meter and so it was not recommended that anyone spend
any extended length of time in this area.
Recommended Permissible Limits of Exposure
The current recommendations for any person exposed to continuous or pulsed
electromagnetic radiation in the frequency range 10 MHz - 300 GHz, are given in the table
below. The following values should not be exceeded in anyone-hour period:
A verage energy flux
1 mW h cm- 2
A verage power density
1 mW cm- 2
A verage electric field strength
60 V m- 1
A verage magnetic field strength
0.16 A m- 1
Maximum average power density (averaged
25mWcm- 2
over one minute)
- 6 Thus for a given average power density P (mW cm - 2), the maximum exposure time t
(minutes) for anyone-hour period is gi ven by the expression t = 60/P.
Conclusions
From the results of this survey and the data gathered during "other surveys", it appears
that within and around the CN Tower and in buildings in downtown Toronto normally occupied
by the public, microwave radiation levels were well within permissible limits. Within the
CN Tower, at locations generally occupied by workers and not normally frequented by the
public, microwave radiation levels were also found to be well within the permissible limits.
Measurements taken at generally inaccessible locations around the antenna feed
dividers and near the vibration dampers, were significantly higher. However, when one
accounts for the occupancy of the areas, the microwave radiation levels were within the
recommended exposure limits for microwave radiation workers.
At the time of the survey all equipment had not been installed at the CN Tower,
and some broadcasting stations had not been operating at their fully licenced power levels.
However, based on the data gathered during the survey, it is expected that the power density
levels in all accessible areas will still be within the recommended limits. There does not
appear to be a health hazard to either the microwave radiation workers or the general public
from the electromagnetic transmissions of the CN Tower.

APPENDIX F
A summary of the results of a preliminary survey carried out by EMI Sound and Vision
Limited is given below. It is not known what instrument was used in the surveyor the precise
locations of their measurements.
a) From top of concrete to underside of FM Antenna
Less than 50 volts per meter.
b) Below FM Aperture above top of concrete outside Antenna Mast
Less than 50 volts per meter, but it should be noted that in certain locations within
18 cm of electrical conduit or feedlines, the reading was 200 volts per meter.
c) Channel 5 Aperture
50 volts per meter and within 15 em of the feedline 150 - 200 volts per meter.
d) FM Antenna
o - less
than 50 volts per meter.
e) Platform between 5 and FM Area
Less than 50 volts per meter.
f)
Platform between Channel 5 and 9
Less than 50 volts per meter.
g) Damper area between Channel 5 and 9
Less than 50 volts per meter, did not obtain any reading more than 100 volts per
meter.
h) Channel 9
Generally the reading taken in this area in the location where a person is passing
through this level, the readings were less than 100 volts per meter. There are isolated
pockets close to certain feedlines and conduits which rendered a reading of 200 300 volts per meter. This was within 18 cm of a conductor.
i)
Channels 19/25 and 79
Readings generally were less than 50 volts per meter and in the Channel 79 area,
less than 10 volts per meter.
j)
Top Deck above Antenna Mast
No appreciable readings at this level.
