The University registration(s) were issued by the Massachusetts Department of Public Health Radiation Control Program for use in research, dentistry and veterinary diagnostic imaging.
X-ray radiation sources are divided into two categories; those machines intended to produce x-ray radiation and those machines that are not intended to produce radiation, but emit x-ray radiation due to the inherent design of the system.
Three areas that use x-ray machines at Tufts University:
For the purpose of radiation protection, several exposure groups as listed below have been established to monitor radiation dose and ensure As Low as Reasonably Achievable (ALARA) conditions. The external radiation source dosimetry program is designed to monitor radiation exposure to areas or individuals as generated by radiation producing machines. Assignment is based upon the likelihood for a workers exposure to approach a fraction of the regulatory limit established by the TU Radiation Safety Committee. Dosimeters are supplied and processed by an accredited outside vendor. Radiation Safety personnel administers the dosimetry program on all campus locations as a service. Instructions for the appropriate location and use of each dosimeter assigned is detailed in RSP-063.
Types of machines that emit radiation vary depending on application and use. Provided below are examples of machines that emit radiation in research or medical application.
Common x-ray radiation producing machines or systems:
Radiation producing machines potentially can cause injury and should be used by trained personnel only. Training is provided by EHS and documented prior to handling any radiation producing machine. X-ray machines used at Tufts University for research, diagnostic purposes in dentistry, or veterinary medicine are required to be registered with the RSO by using form RSP-072: “Radiation Producing Machines Permit Application”.
Please refer to Tufts University Radiation Safety Committee Policies and Procedures Manual for further information regarding the Radiation Safety Program, the Radiation Safety Committee or controls employed to safely use x-ray machines at Tufts University.
