| Título | Exposure levels in close proximity of radiocommunication antennas |
| Resumo | The guidance concerning the exposure levels in close proximity to transmitting antennas is important for safety of the radiocommunication staff operating in such areas. Recommendation ITU-T K.122 gives information concerning the electric field strength levels that can be expected in close proximity to the broadcasting and radiocommunication antennas so that a comparison with the exposure limits is possible. This is important for maintenance personnel and in some cases also for the general public. In the case of workers it is recommended that affected personnel should be trained by expert staff so that they are able to assess the exposure levels in close proximity of radiocommunication antennas. There are many possible configurations of transmitting antennas. In this Recommendation the most typical ones are presented, in order to give general information about exposure levels that can be expected during the operation of radiocommunication systems. |

| Título | Generation of radiofrequency electromagnetic field level maps |
| Resumo | Recommendation ITU-T K.113 provides guidance on how to make radiofrequency electromagnetic field (RF-EMF) maps for assessing existing exposure levels over large areas of cities or territories and for an appropriate public disclosure of the results, in a simple and understandable way. |

| Título | Additional criteria to protect telecommunication cabling during a power cross event |
| Resumo | The objective of Supplement X to the ITU-T K-series Recommendations, Additional criteria to protect telecommunication cabling in the event of a power cross event, is enable the implementation of power cross protection for telecommunications cabling connected to [b-ITU-T K.20], [b-ITU-T K.21] and [b-ITU-T K.45] compliant equipment. This additional criteria to protect telecommunication cabling in the event of a power cross event supplement aims to: • Provide current-time limitations to protect telecommunication cabling from fusing and wire insulation damage. • Explain the evolution of physical wiring simulators and their drawbacks • Provide designers with the tools to extrapolate the supplement current-time limitations data to larger and smaller conductor sizes. |
