There are two companies that we are aware of that offer online radiation detector maps of the United States.  They also sell software which logs the clicks of geiger counters.

The first link is to www.blackcatsystems.com RadMap.  They also hapen to sell an excellent radiation detection system for your Macintosh or Windows PC.  Click here to view.

The second link is to RadiationNetwork.com.  It has been around longer, and has a few more users.  Click here to view.
