Scope
This Recommendation aims to help with compliance of telecommunication installations with safety limits for human exposure to electromagnetic fields (EMFs) produced by telecommunication equipment in the frequency range 8.3 kHz to 300 GHz1. This Recommendation provides techniques and procedures for assessing the severity of field exposure and for limiting the exposure to workers and the general public to these fields if the limits are exceeded. This Recommendation also applies to exposure due to mobile handsets or other radiating devices@ operating in the frequency range 300 MHz to 3 GHz and used against the head. Where national laws@ standards or guidelines on exposure limits to EMF exist and provide procedures that are at variance with this Recommendation@ the pertinent national laws@ standards or guidelines shall take precedence over the procedures provided in this Recommendation. This Recommendation covers the exposure of people present on telecommunication sites@ and the exposure of people outside telecommunication sites@ to EMF produced by telecommunication equipment and equipment on telecommunication sites. Contact current exposure@ due to contact with conductive objects irradiated by electromagnetic fields@ is not covered in this Recommendation. Exposure due to the use of mobile handsets or other radiating devices@ used in close proximity to the human body other than the head@ is not covered. [b-ITU-T Dir. VI] covers safety issues related to people coming in contact with telecommunication circuits exposed to the induction of a.c. electric power or a.c. electrified railway lines 1 Appendix I also gives the ICNIRP limits for lower frequencies
