The Radiation Research Program has a strong commitment to promoting the highest standards in radiotherapy delivery and evaluation. The Advanced Technology Consortium (ATC) and Quantitative Imaging Network (QIN) address these issues. RRP is also committed to promoting equal access to healthcare for underserved populations. These efforts include the Cancer Disparities Research Partnership initiated in 202 and current efforts to develop a "Cancer Experts Corps" to provide mentoring to physicians in under-developed areas. RRP also serves as the NCI's liaison and advisor on mitigation of radiation normal tissue injury in programs addressing radiological/nuclear terrorism in National Institute for Allergies and Infectious Diseases (NIAID) and the Office of the Assistant Secretary for Preparedness and Response (ASPR). In addition to these activities RRP sponsors workshops to promote research in topics that are of a high priority to the NCI mission.
