ITU-R BS.1698 FRENCH-2005在任何频段操作的用于评估非电离辐射暴露的地面广播传输系统评估领域(问题:ITU-R 50/6)

This Recommendation is intended to provide a basis for the derivation and estimation of the values of electromagnetic radiation from a broadcasting station that occurs at particular distances from the transmitter site. Using such information, responsible organizations can then develop appropriate standards that may be used to protect humans from undesirable exposure to harmful radiation. The actual values to be applied in any regulation will naturally depend on decisions reached by responsible health agencies, domestic and worldwide.

ITU-R RAPPORT SM.2130 FRENCH-2008无线电台的检查

This Report presents an overview of Inspections Procedures in response to Question ITU-R 225/1 regarding inspection techniques and procedures. The Question relates to how administrations proceed in planning and conducting radio station inspections. The purpose of this Report is to provide general guidelines for planning and performing inspection activities on various types of radio stations. Inspection activities often include review and verification of both technical and administrative conditions assigned to a radio station or other spectrum user. Although the term “licensed” is used throughout the document, this term can be considered here to include not only stations with licences issued by the regulatory authority, but also other authorized spectrum users (such as those operating with “licence exempt” devices like low-power radios and RF devices operating under equipment standards approval). The primary focus of this report is to consider inspections that are conducted “on-site”, by visiting the transmitter location. Included in Annexes are some specific examples in certain services, toprovide examples of howthe general guidelines can be applied. This Report should be considered a general guidance document for inspections planning.
