                                     Radiation Hazard Analysis

1.0 Introduction

This Exhibit analyzes the non-ionizing radiation levels for the earth stations included in this
application. The analysis and calculations performed in this Exhibit comply with the methods
described in the FCC Office of Engineering and Technology Bulletin, No. 65 first published in 1985
and revised in 1997 in Edition 97-01.

Bulletin No. 65 and the FCC R&O 96-326 specifies two Maximum Permissible Exposure (MPE)
limits that are dependent on the situation in which the exposure takes place and/or the status of the
individuals who are subject to the exposure. These are described below:

• General Population/Uncontrolled environment MPE limit is 1 mW/cm2. The General Population /
Uncontrolled MPE is a function of transmit frequency and is for an exposure period of thirty minutes
or less.

• Occupational/Controlled environment MPE limit is 5 mW/cm2. The Occupational MPE is a function
of transmit frequency and is for an exposure period of six minutes or less.

The analysis determined the power flux density levels of the earth station in the 1) far-field, 2) near-
field, 3) transition region, 4) region between the feed and main reflector surface, 5) at the main
reflector surface, and 6) between the antenna edge and the ground. The summary of results and
discussion is provided in Section 2 and the detailed analyses are provided in Section 3.

Section 2.0 – Summary of Results

The terminals proposed in this application are for professional use and not for use by the general
public. The analysis of the non-ionizing radiation levels provided in Section 3 assumed the maximum
allowed input power to antenna of 5W and a 100% duty cycle resulting in worst case radiation levels.
In a significant number of deployments the terminals duty cycle would be below 100% and the actual
power required would be lower than the 5W maximum resulting in lower radiation levels than those
calculated. As with any directional antenna the maximum level of non-ionizing radiation is in the
main beam of the antenna that is pointed to the satellite. As one moves around the antenna to the side
lobes and back lobes the radiation levels decrease significantly. So the maximum radiation level from
an antenna occurs in a limited area in the direction the antenna is pointed to. The terminals proposed
in this application are designed not to transmit if the receive signal from the satellite is blocked, which
could be caused by a person standing in front of the terminal or from other blockage. If the receive
signal is blocked the transmitter is shut down and will not resume operating until the signal from the
satellite is reacquired. This operational feature of the terminal minimizes the potential for human
radiation exposure. The terminals will be turned off prior to any maintenance being conducted when a
person may need to be in close proximity to the feed flange and main reflector.

The Tables below summarize the result for each antenna terminal type. As shown all but the two
smaller antenna terminals meet the controlled environment limit of ≤ 5 mW/cm2 except at the feed
flange. For the two smaller antennas the level is also exceeded at the main reflector. In a controlled
environment technicians are trained and procedures are put in place to ensure that a safe distance is
maintained from the antenna while in operation. These procedures can include fencing around the
terminal, limits on the operation of the terminal, warning signs and other means of alerting workers,
as appropriate, for the specific deployment scenario.


The terminals when operating with maximum input power and a 100% duty cycle vary in meeting the
uncontrolled environment limit of ≤ 1 mW/cm2. For the 1.8 m antenna the limit is met except at the
feed flange, however for most of the other antennas the level is exceeded except in the far field. As
described above the maximum radiation levels occur in a limited area in the direction the antenna is
pointed to and the automatic shut off capability of the terminal when the satellite receive signal is
blocked will reduce potential human exposure. In addition these terminals are for professional use so
the operators will be trained in how to operate the terminal safely. Furthermore the manuals for these
terminals will explicitly indicate that precautions, such has not standing in front of the terminal, are
required to limit potential exposure. The terminals will also clearly be marked to ensure that the
terminal operator and the general public are aware of the potential radiation exposure and the need to
avoid physical proximity to the terminal. It is noted that the highest radiation levels are at the feed
flange and main reflector. The feed flange is a very small area of the terminal antenna and it is
extremely unlikely that a person would be near the feed flange or the main reflector while the terminal
is in operation.
