This site appears to be similar to mine. It has a few sentences on many topics of interest, and was a great start.
"Thorium: History." Nautilus. 8 Apr 2009 <http://nautilus.fis.uc.pt/st2.5/scenes-e/elem/e09010.html>
This site provided much of my information for the history of Thorium. Its reliability seems questionable but it was backed up by many other sources.
"Thorium (Th) - Chemical properties, Health and Enviornmental effects." Lenntech. 1998. Lenntech. 8 Apr 2009 <http://www.lenntech.com/periodic-chart-elements/th-en.htm>
This was probably my most informative site. It had plenty of accurate information about Thorium's applications, history, and properties.
"Thorium, Checmial Element - Overview, Discovery and naming, Physical properties, Chemical properties, Occurence in nature, Isotopes." Chemistry Explained. 2008. 8 Apr 2009 <http://www.chemistryexplained.com/elements/T-Z/Thorium.html>
This site provided mediocre info on history and properties of Thorium. It was mostly reiterated by other sources.
