The following is a list of sites that we recommend for people who want to get more information about RF safety. There has been no attempt to include every site that is related to the topic. These are the ones that we feel are the most useful, accurate and informative.

The RF Safety Committee has, at one time, reviewed the content of each of the following sites. To the best of our knowledge, the information that was contained there at that time was accurate. However, we cannot guarantee that everything contained in these sites is correct, particularly when it has been modified following our review.
