RF Safety Committee Activities.  \n2. Monitoring current events and scientific studies regarding RF Safety.  \n3. Participation in the scientific RF Safety community.  \n4. Administrative issues.  \n1  RF Safety Committee Activities  \n1.1 Dr. Lapin has written an entirely new RF Safety chapter for the 2023 edition ofthe ARRL Antenna Book. While the new Handbook material provides a basic explanation of the reasoning for and background of RF safety standards and regulations, the new Antenna Book material is directed toward the more technically oriented radio amateur. It concentrates on more exacting methods of analyzing exposure and antenna modifications that can be used to ameliorate high exposure scenarios. Antenna modeling examples of antennas that are commonly used and present potential exposure problems have been included.  \n1.2 The Committee submitted its final contributions to the FCC publication OET Bulletin 65 Supplement B, Evaluating Compliance with FCC Guidelines for Human Exposure to Radiofrequency Electromagnetic Fields, Additional Information for Amateur Radio Stations. The new document is still undergoing the review process by various government entities as is the publication of the rewritten OET Bulletin 65.  \n1.3 Dr. Lapin published an article in the May 2023 edition of QST to remind amateurs that the FCC’s 2-year transition period would end on May 3, 2023 and that all radio amateurs are now expected to perform exposure evaluations, or alternately perform the FCC’s exemption analysis, for their stations. Following publication of this article, comments and questions were received from 23 radio amateurs, all of which were answered by Dr. Lapin. The majority of the questions were about using the ARRL Online Exposure Calculator with different antenna types. Even though many antenna that radio amateurs use do not have their specifications, such as antenna gain, reported by their manufacturers, it is possible to obtain an estimate for use in an exposure calculator. This may be a reasonable topic for a future QEX article.  \n1.4 The question of how the FCC is going to treat the exposure evaluation of handheld radios by radio amateurs got some clarification. Handheld radios are treated differently than fixed transmitters with respect to exposure since their antennas are typically less than 20 cm from the body. Under that condition the FCC requires SAR analysis, which is both complicated and expensive to either measure or model. The Committee was hoping that manufacturers would perform SAR testing on amateur HTs prior to their release, just as they do for commercial HTs and cellular telephones, and supply those results to radio amateurs. However, since the FCC does not require most equipment developed for amateur radio to be certified, so they could not compel this testing and the manufacturers chose not to do so. In an attempt to understand if an issue exists, Mr. Tell reviewed the FCC equipment authorization database for commercial radios similar to amateur HTs and found that they all had passed SAR testing without approaching the FCC mandated limits. He postulated that this could be used as evidence that exposure from amateur HTs similar to the commercial radios in the FCC database could also be assumed to be in compliance with FCC limits. Mr. Tell published this study (Amateur Portable Radios (Handheld Transceivers): Exposure Considerations  \nBased on SAR, QEX, July/August 2021, pp. 11-15) . Communications with the engineers at the FCC have indicated that they are willing to accept this logic as evidence of compliance with the exposure regulations. However, they cautioned that this is not a blanket exemption from performing SAR analysis on handheld radios and there must be a strong similarity between the radio in the FCC equipment database and the ama","cbCaioM7CNxJeM6M","https://ap.wps.com/l/cbCaioM7CNxJeM6M","pdf",195424,"English","# Report of the RF Safety Committee to the ARRL Board of Directors\n## RF Safety Committee Activities\n## Monitoring Current Events and Scientific Studies\n## Participation in the Scientific RF Safety Community","[{\"question\":\"What main work areas did the RF Safety Committee cover during the past six months?\",\"answer\":\"The report covers RF Safety Committee activities, monitoring current events and scientific studies related to RF safety, and participation in the scientific RF safety community.\"},{\"question\":\"How did the committee contribute to FCC guidance for human exposure to radiofrequency electromagnetic fields?\",\"answer\":\"It submitted final contributions to the FCC publication OET Bulletin 65 Supplement B, including additional information for amateur radio stations.\"},{\"question\":\"What guidance did the report provide regarding exposure evaluation for handheld radios?\",\"answer\":\"Handheld radios are handled differently because their antennas are typically less than 20 cm from the body, requiring SAR analysis.
