Exposures

Radiofrequency Radiation Protection Guidelines

• Telecommunication Technology Council (TTC)
  reported Radiofrequency Radiation Protection
  Guidelines for Human Exposure to Electromagnetic
  Fields (RRPG) to Ministry of Posts and
  Telecommunications (MPT) in 1990.
• TTC revised RRPG in 1997.
• MPT begun legislation of parts of RRPG since 1999
  and 2002.

EMF strength guidelines for general conditions
Average Time 6min
f denotes the frequency in MHz.
5
Guidelines for Local Exposure Conditions

• When a human body is locally exposed to EMF,
  spatial average and peak strength of incident EMF
  in the space where the human body would occupy.

6
RRPG and ICNIRP guidelines
E-field strength V/m
Frequency Hz
Japanese guidelines are basically harmonized with
the international guidelines (ICNIRP) in
millimeter-wave band although there are some
differences (averaging time and maximum peak
guidelines).
