Radiation Safety Training

Students have to take and pass the online Purdue REM Ionizing Radiation Producing Equipment Training for X-ray Diffraction and Crystallography before they can independently work in the X-ray diffraction laboratory. This includes the laboratory sections of X-ray Crystallography 12650 - CHM 69600-006. Follow the link to the REM training module page, scroll down to X-ray Diffraction and Crystallography (alphabetical listing) and click the icon on the left to start presentation and quiz. Once you completed the online training you will receive an e-mail informing whether you passed. Forward this e-mail to Dr. Zeller. The form A4 is no longer required.
