About Radium Technologies Radium Technologies is located in El Dorado Hills, California. We were founded in 1998 with the goal of creating powerful, low-cost business and consumer database applications. We have achieved this goal by creating an application framework from which all of our software is built. Living Cookbook was released in 2001, followed by Bartender's Companion in 2002. Diet Pro and EveryLastRecipe.com (our first web application) were released in 2003.
