These presentations were created and edited by the Science Teacher Workshop Committee of the Health Physics Society for the annual American Radiation Safety Conference and Exposition (Health Physics Society's 46th Annual Meeting) held June 10-14, 2001 in Cleveland, Ohio. The modules were peer reviewed by the Public Education Committee of the Health Physics Society. It should be noted that all members of these committees work on a volunteer basis and their effort is greatly appreciated. The education modules were created in Microsoft Powerpoint 2000 or Microsoft Word 2000. Included on this CD should be six directories or file folders. Each file folder contains a powerpoint presentation and a "packed" version of the presentation. If you do not have Powerpoint installed on your computer simply double click on the .exe file and the file will automatically be unpacked and can be viewed as a slideshow. You will not have the ability to edit the presentations if you use this mode of presentation. Also included on the disk are two word files. If you have any questions please contact the Health Physics Society 1313 Dolley Madison Blvd. Suite 402 McLean, VA 22101 (703) 790-1745 or hps@burkinc.com or http://www.hps.organd ask to be referred to the chair of the Science Teacher Workshop Committee. Please feel free to edit these files in any manner which is appropriate with the application in which you intend to use them. Compact Disk Reproduction services provided by OneOff Media, Inc.
