Sec. 2.1093  Radiofrequency radiation exposure evaluation: portable 
          devices.

    (b) For purposes of this section portable devices are defined as 
transmitters designed to be used within 20 centimeters of the body of 
the user.
    (c) Portable devices that operate in the Cellular Radiotelephone 
Service, the Personal Communications Services, the Satellite 
Communications Services, the Wireless Communications Service, the 
Maritime Services and the Specialized Mobile Radio Service authorized 
under subpart H of part 22 of this chapter, part 24 of this chapter, 
part 25 of this chapter, part 27 of this chapter, part 80 of this 
chapter (ship earth station devices only), part 90 of this chapter 
(``covered'' SMR devices only, as defined in the note to Table 1 of 
section 1.1307(b)(1) of this chapter), and portable unlicensed personal 
communication service and millimeter wave devices authorized under 
Sec. 15.253, Sec. 15.255 or subpart D of part 15 of this chapter are 
subject to routine environmental evaluation for RF exposure prior to 
equipment authorization or use. All other portable transmitting devices 
are categorically excluded from routine environmental evaluation for RF 
exposure prior to equipment authorization, except as specified in 
Secs. 1.1307(c) and 1.1307(d) of this chapter. Applications for 
equipment authorization of portable transmitting devices subject to 
routine environmental evaluation must contain a statement confirming 
compliance with the limits specified in paragraph (d) of this section as 
part of their application. Technical information showing the basis for 
this statement must be submitted to the Commission upon request.
    (d) The limits to be used for evaluation are based generally on 
criteria published by the American National Standards Institute (ANSI) 
for localized specific absorption rate (``SAR'') in Section 4.2 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. These criteria 
for SAR evaluation are similar to those recommended by the National 
Council on Radiation Protection and Measurements (NCRP) in ``Biological 
Effects and Exposure Criteria for Radiofrequency Electromagnetic 
Fields,'' NCRP Report No. 86, Section 17.4.5. Copyright NCRP, 1986, 
Bethesda, Maryland 20814. SAR is a measure of the rate of energy 
absorption due to exposure to an RF transmitting source. SAR values have 
been related to threshold levels for potential biological hazards. The 
criteria to be used are specified in paragraphs (d)(1) and (d)(2) of 
this section.
