Título | Monitoring of electromagnetic field levels |
Resumo | Recommendation ITU-T K.83 gives guidance on how to make long-term measurements for the monitoring of electromagnetic fields (EMF) in the selected areas that are under public concern, in order to show that EMFs are under control and under the limits. The purpose of this Recommendation is to provide for the general public clear and easily available data concerning electromagnetic field levels in the form of results of continuous measurement. |

Título | Measurement of radio frequency electromagnetic fields to determine compliance with human exposure limits when a base station is put into service |
Resumo | Recommendation ITU-T K.100 provides information on measurement techniques and procedures for assessing compliance with the general public electromagnetic field (EMF) exposure limits when a new base station (BS) is put into service, taking into account effects of the environment and other relevant radio frequency sources present in its surroundings. |

Título | Guidance for assessment, evaluation and monitoring of human exposure to radio frequency electromagnetic fields |
Resumo | There are many possible methods of exposure assessment and each of them has its own advantages and disadvantages. Recommendation ITU-T K.91 gives guidance on how to assess and monitor human exposure to radio frequency (RF) electromagnetic fields (EMFs) in areas with surrounding radiocommunication installations based on existing exposure and compliance standards in the 9 kHz to 300 GHz range. This includes procedures for evaluating exposure and how to show compliance with exposure limits with reference to existing standards. Recommendation ITU-T K.91 is oriented to the examination of the area accessible to people in the real environment of currently operated services with many different sources of RF EMF, but also gives references to standards and Recommendations related to EMF compliance of products. Recommendation ITU-T K.91 includes an electronic attachment containing an uncertainty calculator and the Watt guard modules. |

Título | Supplement on radiofrequency exposure evaluation around underground base stations |
Resumo | Measurement and computation methods of human exposure to electromagnetic fields (EMFs) from fixed radio sources like mobile base stations have been standardized and published as ITU-T K-series Recommendations and IEC 62232. These also include methods prescribed in Japanese regulation and have been basically assumed to be applied to radio sources installed above the ground. Underground base stations for use in small cells of fourth generation (4G) mobile networks are installed underground to construct service areas above the ground. Supplement 20 to ITU-T K-series Recommendations contains the measurement results of radio frequency exposure from underground base stations, to evaluate the exposure from these base stations. |

Título | Radiofrequency electromagnetic field (RF-EMF) exposure levels from mobile and portable devices during different conditions of use |
Resumo | Modern mobile devices may be used for many different purposes. There are differences between the ways of using them depending on the service. Also, the exposure to RF-EMF is different depending on the service, environment and the conditions of the use of the mobile devices. This Supplement describes the various factors that determine the level of RF-EMF exposure, as defined by the specific absorption rate (SAR) that is induced in the users of mobile and portable radiocommunication devices. Based on this technical information practical information and guidance is provided for users of mobile devices. |
