Title:     Mission and Ongoing Research Activities at Oak Ridge National Laboratory's Center for Radiation Protection Knowledge

Abstract: For decades, Oak Ridge National Laboratory (ORNL) has led the effort in the computation of internal and external dose coefficients in the support of federal regulations and international guidance. A dose coefficient is a measure of radiation dose (e.g., absorbed or equivalent dose rate, committed equivalent dose, or committed effective dose) to a specified tissue or to the whole body per unit intake of a radionuclide, for internal emitters, and per unit concentration of a radionuclide in an environmental medium, for external irradiation. Dose coefficients have applications in a variety of fields, including occupational radiation protection, emergency response, and nuclear medicine. The Center for Radiation Protection Knowledge (CRPK) was established within the Environmental Sciences Division at ORNL as part of a memorandum of understanding (MOU) between ORNL and five U.S. federal agencies in 2010. In keeping with its MOU stated mission to maintain and preserve expertise in radiation dosimetry, the principal ongoing research activity to be presented will be the development of dose coefficients for a variety of internal and external dosimetry applications based on the latest International Commission on Radiological Protection (ICRP) definitions/recommendations.  

Other recent projects such as the computation of public doses due to the release of patients administered I-131, using handheld detectors to assess internal uptake during an RDD event, as well as updates to the Phantom with Moving Arms and Legs (PIMAL) software and the Dose Coefficient Package (DCFPAK), will also be presented. 

The ORNL-CRPK activities should be of interest to a broad audience as they are applicable to radiation protection in accelerator facilities, medical physics, nuclear medicine, RDD and IND radiation impacts for emergency response, radiological assessments for a variety of nuclear facilities and activities, radiation risk assessment, and the construction of pathway dose conversion coefficients.
