Título Guidance on complying with limits for human exposure to electromagnetic fields
Resumo Recommendation ITU-T K.52 aims to help with compliance of telecommunication installations and mobile handsets, or other radiating devices used against the head with safety limits for human exposure to electromagnetic fields (EMFs). It presents general guidance, a calculation method and an installation assessment procedure. The assessment procedure for telecommunication installations, based on safety limits provided by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), helps users determine the likelihood of installation compliance based on accessibility criteria, antenna properties and emitter power. The IEC Standard for the compliance measurement of mobile handsets is recommended.

Título Guide on electromagnetic fields and health
Resumo The objective of Supplement 1 to the ITU-T K-series Recommendations is to answer questions commonly posed by the public on the electromagnetic field (EMF) phenomenon and to address related concerns. This Guide on electromagnetic fields and health aims to:• Provide electromagnetic field (EMF) information and education resources suitable for all communities, stakeholders and governments.• Support clarification of the science by referencing the World Health Organization (WHO) and other stakeholders (see NOTE) that provide information that is particularly useful in helping to clarify scientific uncertainties e.g., in the areas of radio frequency (RF) technology, infrastructure implementation, usage and consequential EMF exposure.NOTE – The primary reference on EMF and health is the World Health Organization (WHO). The primary reference on EMF assessment methods is the International Telecommunication Union (ITU) and the International Electrotechnical Commission (IEC).

Título Mitigation techniques to limit human exposure to EMFs in the vicinity of radiocommunication stations
Resumo Recommendation ITU-T K.70 defines techniques which may be used by telecommunication operators to evaluate the cumulative (total) exposure ratio in the vicinity of transmitting antennas and to identify the main source of radiation. It offers guidance on mitigation methods which allow reduction of radiation level in order to comply with exposure limits. It also provides guidance on procedures necessary in the environment (on site) in which, in most cases, there is a simultaneous exposure to multiple frequencies from many different sources. Radiating sources may belong to many operators and may represent different radiocommunication services (e.g., cellular systems, trunking systems, broadcasting, radio relays, wireless access, etc.). Appendix I includes an electronic attachment with distinct 32-bit and 64-bit versions of the EMF estimator software. As Microsoft Access 32-bit and 64-bit versions cannot be served by the same software package, two versions of this software are proposed. Furthermore, two separate install procedures are required in order to run this software depending on the Microsoft Access version installed on the user PC.

Título Assessment and management of compliance with radio frequency electromagnetic field exposure limits for workers at radiocommunication sites and facilities
Resumo Recommendation ITU-T K.145 includes guidance on the protection of workers against radio frequency electromagnetic fields (RF-EMFs) exposure in their working environments. Radio frequency (RF) workers range from installation engineers and tower climbers to R&D personnel and laboratory testing engineers. All of these RF workers are exposed to stronger RF-EMF fields than the general public. There are also RF informed workers who have been provided with information on RF-EMF safe working practices for a site as well as all other workers who are regarded as members of the public for the purposes of RF-EMF exposure limits. This Recommendation provides minimum general safety guidance for telecommunication RF workers around the world

Título The impact of RF-EMF exposure limits stricter than the ICNIRP or IEEE guidelines on 4G and 5G mobile network deployment
Resumo Radio frequency electromagnetic field (RF-EMF) exposure limits have become a critical concern for further deployment of wireless networks, especially in countries, regions and even specific cities where RF-EMF limits are significantly stricter than the International Commission for Non-Ionizing Radiation Protection (ICNIRP) or Institute of Electrical and Electronics Engineers (IEEE) guidelines. This problem currently affects several countries, such as China, India, Poland, Russia, Italy and Switzerland, regions of Belgium or cities such as Paris. Supplement 14 to the ITU-T K-series of Recommendations provides an overview of some of the challenges faced by countries, regions and cities that are about to deploy 4G or 5G infrastructures. It provides information on a simulation carried out in Poland of the impact of RF‑EMF limits as an example of a wider phenomenon, applicable to several other countries that have set limits stricter than those contained in the ICNIRP or IEEE guidelines. The results of the simulation indicate that, where RF-EMF limits are stricter than ICNIRP or IEEE guidelines, the network capacity buildout (both 4G and 5G) might be severely constrained and prevent growing data traffic demand and the launching of new services on existing mobile networks being addressed.
