  2. Japanese Safety Regulation for Millimeter-Wave Exposures Hiroyo Ogawa, NICT

  3. 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. Hiroyo Ogawa, NICT

  4. EMF strength guidelines for general conditions * f denotes the frequency in MHz. Average Time :6min Hiroyo Ogawa, NICT

  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. Hiroyo Ogawa, NICT

  6. Japanese guideline (RRPG) ICNIRP guideline 104 103 275 61.4 102 27.5 101 10k 100k 1M 10M 100M 1G 10G 100G 1T 100 3M 30M 300M 1.5G 300G 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).
