Sec.  1.1310   Radiofrequency radiation exposure limits.

   The criteria listed in table 1 shall be used to evaluate the environmental
   impact of human exposure to radiofrequency (RF) radiation as specified in
    Sec. 1.1307(b), except in the case of portable devices which shall be evaluated
   according to the provisions of  Sec. 2.1093 of this chapter. Further information
   on evaluating compliance with these limits can be found in the FCC's OST/OET
   Bulletin Number 65, “Evaluating Compliance with FCC-Specified Guidelines for
   Human Exposure to Radiofrequency Radiation.”

   Note to Introductory Paragraph: These limits are generally based on
   recommended exposure guidelines published by the National Council on
   Radiation Protection and Measurements (NCRP) in “Biological Effects and
   Exposure Criteria for Radiofrequency Electromagnetic Fields,” NCRP Report
   No. 86, Sections 17.4.1, 17.4.1.1, 17.4.2 and 17.4.3. Copyright NCRP, 1986,
   Bethesda, Maryland 20814. In the frequency range from 100 MHz to 1500 MHz,
   exposure limits for field strength and power density are also generally
   based on guidelines recommended by the American National Standards Institute
   (ANSI) in Section 4.1 of “IEEE Standard for Safety Levels with Respect to
   Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300
   GHz,” ANSI/IEEE C95.1–1992, Copyright 1992 by the Institute of Electrical
   and Electronics Engineers, Inc., New York, New York 10017.

Note 1 to Table 1: Occupational/controlled limits apply in situations in which
persons are exposed as a
  consequence of their employment provided those persons are fully aware of the
 potential for exposure and can
  exercise control over their exposure. Limits for occupational/controlled expo
sure also apply in situations
  when an individual is transient through a location where occupational/control
led limits apply provided he or
  she is made aware of the potential for exposure.
Note 2 to Table 1: General population/uncontrolled exposures apply in situation
s in which the general public may
  be exposed, or in which persons that are exposed as a consequence of their em
ployment may not be fully aware
  of the potential for exposure or can not exercise control over their exposure
.
