Introduction
July 21, 2008
At your request, I have reviewed the technical specifications and calculated the maximum radio frequency,
(RF), power density from the existing T-Mobile (TM) wireless telecommunications site, (referenced as SD-
06436), which is located at the Olympic Hotel 6111 El Camino Real, Carlsbad, California as depicted in
attachment one.
This TM telecommunication site consists of a Personal Communications Services (PCS) wireless facility.
The facility utilizes directional transmit panel antennae configured in three sectors. The antennae are
mounted behind a rooftop screen wall with their center at least 24.0 feet above grade directed at O (sector
A), 120 (sector B), and 240 (sector C) degrees true north. The antennas specified are EMS Wireless model
# RV6518-04DP for all sectors. Technical specifications of these antennae are provided in attachment two.
The sectorized antennas are designed to transmit with an effective radiated power (ERP) ofup to 800 watts
per sector within a bandwidth between approximately 1,850 and 1,990 MHz.
Calculation Methodology, Results & Recommendations
Calculations were made in accordance with the recommendations contained in the Federal Communications
Commission, Office of Engineering and Technology Bulletin 65 (edition 97-01) entitled "Evaluating
Compliance with FCC-Guidelines for Human Exposure to Radio frequency Electromagnetic Fields." Several
assumptions were made in order to provide the most conservative or "worse case" projections of power
densities. Calculations were made assuming that all channels were operating simultaneously at their
maximum design effective radiated power. For public exposure at ground level, attenuation (weakening) of
the signal that would result from surrounding foliage or buildings was ignored. Buildings can reduce the
signal strength by a factor of 10 (i.e., 10 dB) or more depending upon the construction material. The ground
or other surfaces were considered to be perfect reflectors ( which they are not) and the RF energy was assumed
to overlap and interact constructively at all locations (which they would not) thereby resulting in the
calculation of the maximum potential exposure. In fact, the accumulations of all these very conservative
assumptions will significantly overestimate the actual exposures that would typically be expected from such
a facility. However, this method is a prudent approach that errs on the side of safety.

The maximum public RF exposure from this TM facility was calculated to be less than20.6 µW/cm2 ( i.e.,
~2.1 % of the public safety standard at 1,850 MHz). Exposure details are shown in appendix A.
A sign conforming to with ANSI C95 .2 color, symbol and content, and other markings as appropriate, should
be placed close to the antennas with appropriate contact information in order to alert maintenance or other
workers approaching the antenna to the presence of RF transmissions and to take precautions to avoid
exposures in excess of FCC limits.
RF Safety Standards
The two most widely recognized standards for protection against RF field exposure are those published by
the American National Standards Institute (ANSI) C95.1 and the National Council on Radiation Protection
and measurement (NCRP) report #86.
The NCRP is a private, congressionally chartered institution with the charge to provide expert analysis of a
variety of issues ( especially health and safety recommendations) on radiations of all forms. The scientific
analyses of the NCRP are held in high esteem in the scientific and regulatory community both nationally and
internationally. In fact, the vast majority of the radiological health regulations currently in existence can
trace their origin, in some way, to the recommendations of the NCRP.
All RF exposure standards are frequency-specific, in recognition of the differential absorption of RF energy
as a function of frequency. The most restrictive exposure levels in the standards are associated with those
frequencies that are most readily absorbed in humans. Maximum absorption occurs at approximately 80 MHz
in adults. The NCRP maximum allowable continuous occupational exposure at this frequency is 1,000
µW/cm2. This compares to 5,000 µW/cm2 at the most restrictive of the PCS frequencies (~1,800 MHz) that
are absorbed much less efficiently than exposures in the VHF TV band.
The traditional NCRP philosophy of providing a higher standard of protection for members of the general
population compared to occupationally exposed individuals, prompted a two-tiered safety standard by which
levels of allowable exposure were substantially reduced for "uncontrolled " ( e.g., public) and continuous
exposures. This measure was taken to account for the fact that workers in an industrial environment are
typically exposed no more than eight hours a day while members of the general population in proximity to
a source of RF radiation may be exposed continuously. This additional protection factor also provides a
greater margin of safety for children, the infirmed, aged, or others who might be more sensitive to RF
exposure. After several years of evaluating the national and international scientific and biomedical literature,
the members of the NCRP scientific committee selected 931 publications in the peer-reviewed scientific
literature on which to base their recommendations. The current NCRP recommendations limit continuous
public exposure at PCS frequencies to 1,000 µW/cm2 .
The 1992 ANSI standard was developed by Scientific Coordinating Committee 28 (SCC 28) under the
auspices of the Institute of Electrical and Electronic Engineers (IEEE). This standard, entitled "IEEE
Standards for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields,
3 kHz to 300 GHz" (IEEE C95.l-1991), was issued in April 1992 and subsequently adopted by ANSI. A
revision of this standard (C95.l-2005) was completed in October 2005 by SCC 39 the IEEE International
2
Committee on Electromagnetic Safety. Their recommendations are similar to the NCRP recommendation
for the maximum permissible exposure (MPE) to the public PCS frequencies (950 µ W/cm2 for continuous
exposure at 1,900 MHz) and incorporates the convention of providing for a greater margin of safety for public
as compared with occupational exposure. Higher whole body exposures are allowed for brief periods
provided that no 30 minute time-weighted average exposure exceeds these aforementioned limits.
On August 9, 1996, the Federal Communications Commission (FCC) established a RF exposure standard that
is a hybrid of the current ANSI and NCRP standards. The maximum permissible exposure values used to
assess environmental exposures are those of the NCRP (i.e., maximum public continuous exposure at PCS
frequencies of 1,000 µ W /cm2 ). The FCC issued these standards in order to address its responsibilities under
the National Environmental Policy Act (NEPA) to consider whether its actions will "significantly affect the
quality of the human environment." In as far as there was no other standard issued by a federal agency such
as the Environmental Protection Agency (EPA), the FCC utilized their rulemaking procedure to consider
which standards should be adopted. The FCC received thousands of pages of comments over a three-year
review period from a variety of sources including the public, academia, federal health and safety agencies
( e.g., EPA & FDA) and the telecommunications industry. The FCC gave special consideration to the
recommendations by the federal health agencies because of their special responsibility for protecting the
public health and safety. In fact, the maximum permissible exposure (MPE) values in the FCC standard are
those recommended by EPA and FDA. The FCC standard incorporates various elements of the 1992 ANSI
andNCRP standards which were chosen because they are widely accepted and technically supportable. There
are a variety of other exposure guidelines and standards set by other national and international organizations
and governments, most of which are similar to the current ANSI/IEEE or NCRP standard, figure one.
The FCC standards "Guidelines for Evaluating the Environmental Effects of Radiofrequency Radiation"
(Report and Order FCC 96-326) adopted the ANSI/IEEE definitions for controlled and uncontrolled
environments. In order to use the higher exposure levels associated with a controlled environment, RF
exposures must be occupationally related ( e.g., PCS company RF technicians) and they must be aware of and
have sufficient knowledge to control their exposure. All other environmental areas are considered
uncontrolled (e.g., public) for which the stricter (i.e., lower) environmental exposure limits apply. All
carriers were required to be in compliance with the new FCC RF exposure standards for new
telecommunications facilities by October 15, 1997. These standards applied retroactively for existing
telecommunications facilities on September 1, 2000.
The task for the physical, biological, and medical scientists that evaluate health implications of the RF data
base has been to identify those RF field conditions that can produce harmful biological effects. No panel
of experts can guarantee safe levels of exposure because safety is a null concept, and negatives are not
susceptible to proof. What a dispassionate scientific assessment can offer is the presumption of safety when
RF-field conditions do not give rise to a demonstrable harmful effect.
Summary & Conclusions
This TM facility, as specified above will be in full compliance with FCC RF public safety standards. PCS
and cellular transmitters, by design and operation, are low-power devices. Even under maximal exposure
3
conditions in which all the channels from all antennas are operating at full power, the maximum RF exposure
will not be in excess of 2.1 % of the public safety standard at any publically accessible location. This
maximum exposure is more than 47 times lower than the FCC public exposure standards for these
frequencies. A chart of the electromagnetic spectrum and a comparison of RF power densities from various
common sources is presented in :figures two and three respectively in order to place exposures from PCS and
cellular telecommunications systems in perspective.
It is important to realize that the FCC maximum allowable exposures are not set at a threshold between safety
and known hazard but rather at 50 times below a level that the majority of the scientific community believes
may pose a health risk to human populations. Thus the previously mentioned maximum exposure from the
site represent a "safety margin" from this threshold of potentially adverse health effects of more than 2,380
times.
Given the low levels of radiofrequency fields that would be generated from this facility, and given the
evidence on biological effects in a large data base, there is no scientific basis to conclude that harmful effects
will attend the utilization of this wireless telecommunications facility. This conclusion is supported by a
large numbers of scientists that have participated in standard-setting activities in the United States who are
overwhelmingly agreed that RF radiation exposure below the FCC exposure limits has no demonstrably
harmful effects on humans.
These findings are based on my professional evaluation of the scientific issues related to the health and safety
of non-ionizing electromagnetic radiation and my analysis of the technical specification as provided by TM.
The opinions expressed herein are based on my professional judgement and are not intended to necessarily

STATEMENT OF EXPERIENCE
Jerrold Talmadge Bushberg, Ph.D., DABMP, DABSNM
(800) 760-8414 jbushberg@hampc.com
Dr. Jerrold Bushberg has performed health and safety analysis for RF & ELF transmissions systems since
1978 and is an expert in both health physics and medical physics. The scientific discipline of Health
Physics is devoted to radiation protection, which, among other things, involves providing analysis of
radiation exposure conditions, biological effects research, regulations and standards as well as
recommendations regarding the use and safety of ionizing and non-ionizing radiation. In addition, Dr.
Bushberg has extensive experience and lectures on several related topics including medical physics,
radiation protection, (ionizing and non-ionizing), radiation biology, the science of risk assessment and
effective risk communication in the public sector.
Dr. Bushberg1s doctoral dissertation at Purdue University was on various aspects of the biological effects
of microwave radiation. He has maintained a strong professional involvement in this subject and has
served as consultant or appeared as an expert witness on this subject to a wide variety of
organizations/institutions including, local governments, school districts, city planning departments,
telecommunications companies, the California Public Utilities Commission, national news organizations,
and the U.S. Congress. In addition, his consultation services have included detailed computer based
modeling of RF exposures as well as on-site safety inspections and RF & ELF environmental field
measurements of numerous transmission facilities in order to determine their compliance with FCC and
other safety regulations. The consultation services provided by Dr. Bushberg are based on his professional
judgement as an independent scientist, however they are not intended to necessarily represent the views
of any other organization.
Dr. Bushberg is a member of the main scientific body of International Committee on Electromagnetic
Safety (ICES) which reviews and evaluates the scientific literature on the biological effects of non-
ionizing electromagnetic radiation and establishes exposure standards. He also serves on the ICES Risk
Assessment Working Group that is responsible for evaluating and characterizing the risks of non-
ionizingelectromagnetic radiation. Dr. Bushbergwas appointed and is serving as a member of the main
scientific council of the National Council on Radiation Protection and Measurement1s (NCRP). He is
also a Scientific Vice-President of the NCRP, a member of the NCRP Board of Directors and chairs its
committee on Radiation Protection in Medicine. In addition, Dr. Bushberg is a member of NCRP' s
scientific advisory committee on Non-ionizing Radiation Safety. The NCRP is the nation's preeminent
scientific radiation protection organization, chartered by Congress to evaluate and provide expert
consultation on a wide variety of radiological health issues. The current FCC RF exposure safety
standards are based in large part on the recommendations of the NCRP. Dr. Bushberg was elected to
the International Engineering in Medicine and Biology Society Committee on Man and Radiation
(COMAR) which has as its primary area ofresponsibility the examination and interpreting the biological
effects of non-ionizing electromagnetic energy and presenting its findings in an authoritative and
professional manner. Dr. Bushberg is also a member of a six person U.S. expert delegation to the
international scientific community on Scientific and Technical Issues for Mobile Communication
Systems established by the Federal Communications Commission.
Dr. Bushberg is a full member of the Bioelectromagnetics Society, the Health Physics Society and the
Radiation Research Society. Dr. Bushberg received both a Masters of Science and Ph.D. from the
Department of Bionucleonics at Purdue University. Dr. Bushberg is certified by several national
professional boards with specific sub-specialty certification in radiation protection and medical physics.
Prior to coming to California, Dr. Bushberg was on the faculty of Yale University School of Medicine.
