Radiofrequency (RF) is any of the electromagnetic wave frequencies that lie in the range extending from around 3 kHz to 300 GHz, which include those frequencies used for communications or radar signals. RF usually refers to electrical rather than mechanical oscillations. However, mechanical RF systems do exist (ie mechanical filter and RF MEMS).

Although radiofrequency is a rate of oscillation, the term "radiofrequency" or its abbreviation "RF" are used as a synonym for radio — i.e., to describe the use of wireless communication, as opposed to communication via electric wires. Examples include:

  • Radiofrequency identification
  • ISO/IEC 14443-2 Radiofrequency power and signal interface

Electromagnetic Fields and Public Health: Mobile Phones - World Health Organization (WHO)
Mobile or cellular phones are now an integral part of modern telecommunications. In many countries, over half the population use mobile phones and the market is growing rapidly. In 2014, there is an estimated 6.9 billion subscriptions globally. In some parts of the world, mobile phones are the most reliable or the only phones available. Given the large number of mobile phone users, it is important to investigate, understand and monitor any potential public health impact

EMF & Health
The contributors to this site have a professional background in science and technology. They share a common belief in the value of science and technology. Science and the evolution of scientific knowledge serve the interests of decision makers as well as society as a whole. In seeking to promote a greater understanding of the state of true scientific knowledge of EMF & Health, it is important to distinguish between myth and reality, evidence based science and poor science, and to expose pseudoscience. We hope this web site will help inform and enlighten you about the status of mainstream scientific research on the issue of EMF and Health.

Exposure Limits for Radiofrequency Energy: Three Models - Kenneth R. Foster, Department of Bioengineering, University of Pennsylvania, World Health Organization (WHO)
This Conference is entitled "Criteria for EMF Standards Harmonization". Harmonization, used in the present context, is the process of reducing the large discrepancies in EMF exposure standards that are in effect throughout the world.

Potential Health Effects of Exposure to Electromagnetic Fields (EMF) - (PDF), Scientific Committee on Emerging an d Newly Identified Health Risks (SCENIHR)
Update to the the January 2009 SCENIHR opinions "Health effects of exposure to EMF" and July 2009 "Research needs and methodology to address the remaining knowledge gaps on the potential health effects of EMF" with the latest information and to give special consideration to areas where important knowledge gaps were identified in the previous Opinion. In addition, biophysical interaction mechanisms and the potential role of co-exposures to environmental stressors are discussed.

IARC Press Release: Cell Phones a Possible Carcinogen? - EMF & Health
A lot has happened in the past year since IARC issued its report in which it classified cell phones as possibly carcinogenic. We have written a comprehensive update on this report entitled: Are Cell Phones a Possible Carcinogen? An Update on the IARC Report, which is posted on the web site Science Based Medicine. In short the article explains how the evidence on which IARC based its assessment was weak to begin with. It also includes the results of new papers published over the past year that substantially undermine this already weak evidence.

Radiation and Your Health: The Electromagnetic Spectrum - Centers for Disease Control and Prevention (CDC)
Radiation exists all around us, from both natural and manmade sources, and is in two forms: ionizing and non-ionizing radiation. Non-ionizing radiation exists all around us from many sources. It is to the left of ionizing radiation on the electromagnetic spectrum. Examples include: Radiofrequency (RF) radiation used in many broadcast and communications applications, Microwaves used in the home kitchen, Infrared radiation used in heat lamps, Ultraviolet (UV) radiation from the sun and tanning beds.

Radiation-Emitting Products: Current Research Results - US Food and Drug Administration (FDA)
Is there a connection between certain health problems and exposure to radiofrequency fields via cell phone use? The results of most studies conducted to date indicate that there is not. In addition, attempts to replicate and confirm the few studies that did show a connection have failed.

The Sun and Other Types of Radiation: Cellular Phone Towers - American Cancer Society
Some people have expressed concern that living, working, or going to school near a cell phone tower might increase the risk of cancer or other health problems. At this time, there is very little evidence to support this idea. In theory, there are some important points that would argue against cellular phone towers being able to cause cancer.
