A National Register of RF Workers event supported by the Cambridge Wireless Radio Technology SIG which will review the current knowledge of RF Safety.

We’re delighted to announce that this year’s annual event will be held in person for the first time since 2019. It is being hosted at the University of Birmingham’s brand-new conference park and hotel in collaboration with the Radio Tehcnology SIG at Cambridge Wireless.

The event will cover a broad range of topics but with an overarching focus on the implications of RF Safety for the workforce and the general public. The meeting will be conducted across two sessions. The first will explore practical elements of the accurate modelling and measuring of RF exposure at a range of sites. The second will report on the findings of the COSMOS study (the international study exploring the impacts of mobile telephones on public health), the new study exploring the health effects of 5G and the work of the recently launched National Spectrum Centre.

The full day event will have a range of guest speakers from across industry, and academia, including Link Microtek, BT Telecom, Imperial College London and University of Bristol. The day will conclude with a panel discussion where delegates can discuss the themes of the day with the speakers.

Who is it for? The meeting is suitable for senior management, and health, safety and environment professionals in companies where staff exposure to RF can exceed public guidelines. It will be particularly useful for all those who seek further clarity and guidance on the impact of working with RF.

What will I get out of this? Those attending will gain a better understanding of the potential and perceived risk of RF, the practical issues of measuring RF in the workplace and how it might be managed and mitigated.

Please note this event will operate under the Chatham House Rule.

There is a small registration fee of £20 plus VAT to attend. Please note there is limited capacity at this event so early registration is advised.

Hugo Bibby - Technical Director, Link Microtek

Hugo has been measuring EMF for nearly 40 years. For the last 25+ years he’s been a Director at Link Microtek working with test & measurement equipment for ELF, RF & microwave applications. His early career centred on high power amplifiers for defence radar systems but in his time at Link has been involved with various aerospace, broadcast, telecoms, industrial, scientific and medical projects. When not stuck behind a laptop he spends his working day on rooftops or in factories peering at displays of electric and magnetic field strengths. He is a chartered member of the Society for Radiological Protection.

Frank de Vocht - Professor in Epidemiology and Public Health, University of Bristol

Frank de Vocht is a Professor in Epidemiology and Public Health, and joined the Centre for Public Health, which is part of Population Health Sciences at Bristol Medical School in 2014. He is funded by the NIHR School for Public Health Research and NIHR Applied Research Collaboration West (ARC West). He has over 160 peer-review publications broadly covering the areas of public health, exposure measurements and assessment, and radiation, environmental and occupational epidemiology. He has contributed to book chapters on epidemiology, exposure assessment and the effects of electromagnetic fields on humans. His work is funded by NIHR, the European Union and several charities, and he specializes in epidemiology of lifestyle, environmental, and occupational risk factors. His current research interests are two-fold: the evaluation of natural experiments in public health, specifically in the context of alcohol policies, and secondly the effects of ionising and non-ionizing radiation on human health. Frank de Vocht is a member of the Committee on Medical Aspects of Radiation in the Environment (COMARE), IRPA NIR Task Group, SRP EMFOR, and Health Council of the Netherlands. He occasionally consults for EPRI.
