The Radiation Safety Committee (RSC) has determined that five (5) or less of the following FDA approved or cleared scans/x-rays represent no greater than minimal risk and therefore do not require review and approval by the RSC (i.e., you do not need to complete an Application for Human Use of Radiation in Research):

  • DEXA scans
  • Chest x-rays
  • Planar x-rays of extremities (as defined by NRC – hands, forearms, elbows, feet, knees, leg below the knees, and ankles)
  • Dental x-rays

Please note that one procedure could have multiple views/scans (e.g., AP and Lat view for chest x-ray).

The following statement must be included in the risk section of the consent form:

“This research study involves exposure to radiation from (insert maximum number scans and type of procedure). Please note that this radiation exposure is not necessary for your medical care and is for research purposes only.

For comparison, the average person in the United States receives a radiation exposure of 0.3 rem (or 300 mrem) per year from natural background sources, such as from the sun, outer space, and from radioactive materials that are found naturally in the earth’s air and soil. The dose that you will receive from participation in this research study is less than amount you receive from these natural sources in one year.

The amount of radiation you will receive in this study has a minimal risk and is below the dose guideline established by The University of North Carolina Radiation Safety Committee for research subjects.”
