Radiation Producing Devices


Policies and Procedures

Radiation Producing Devices (RPD) are instruments that produce ionizing radiation for sample analysis or imaging. These devices are registered with the Pennsylvania Department of Environmental Protection (PADEP) which regulates their use. Operators of an RPD are required to receive the appropriate radiation safety training. Each RPD must be inspected periodically.


Electron Microscope & XPS Safety Training

The Pennsylvania Department of Environmental Protection requires that all users of Electron Microscopes (EM) and XPS's receive radiation safety training. This training is available to users at Carnegie Mellon through an online powerpoint presentation. A short quiz and user information request follows the training and functions as proof that the user has met the requirement.

X-Ray Safety Training

The X-ray safety training consists of an electronic and practical training presentation. The electronic session is a web-based power point presentation that illustrates many fundamental concepts of ionizing radiation and basics of radiation protection principles. The electronic training session may be accessed at the web-based initial x-ray training link in the helpful links box to the right. After you complete the web-based x-ray safety training, you must contact the manager of the specific x-ray device to schedule the practical training session.

Completion of this course and a passing grade of at least 70% on the written exam fulfill the requirements for you to be approved to use x-ray diffraction equipment, under an existing principal investigator’s authorization, at Carnegie Mellon University .

Please note that this course does NOT fulfill the requirements for use of fluoroscopy units or radionuclides. This course will NOT grant you an AUTHORIZATION to use radiation-producing machinery as a PRINCIPAL INVESTIGATOR, although it is a requirement for principal investigator authorization.
