Medical Radiation Safety: Technologist Perspective

Image Gently

More than 12,000 medical professionals have taken the pledge...have you?

ARRT is among the 13 member organizations of the Image Gently™ Alliance, which promotes "child-size" radiation doses in pediatric imaging care. Providers who perform imaging exams on children are urged to:

  • Significantly reduce, or child-size, the amount of radiation used;
  • Scan only when necessary;
  • Scan only the indicated region; and
  • Scan once: multi-phase scanning (pre- and post-contrast, delayed exams) is rarely helpful.

Image Gently also urges that medical staff be team players:

  • Involve medical physicists to monitor pediatric CT techniques.
  • Involve technologists to optimize scanning.

The Image Gently™ campaign was launched in January 2008 by the Society for Pediatric Radiology (SPR), the American College of Radiology (ACR), the American Society of Radiologic Technologists (ASRT), and the American Association of Physicists in Medicine (AAPM), founding members of the Alliance for Radiation Safety in Pediatric Imaging.

Image Wisely

With medical imaging exams replacing more invasive procedures, benefiting patients and revolutionizing medicine, exposure to medical radiation is also increasing. To help limit unnecessary exposure, the Image Wisely initiative – a collaboration between the American College of Radiology (ACR), the Radiological Society of North America (RSNA), the American Society of Radiologic Technologists (ASRT), and the American Association of Physicists in Medicine (AAPM) – seeks to help ensure that adult patients receive only necessary scans and that those scans use the optimal radiation dose.

U.S. Radiologic Technologists Study

This study joins the resources and expertise of the University of Minnesota, the National Cancer Institute, and ARRT in the largest and most comprehensive study of people who are exposed to radiation in medical jobs in the world. It is also unique as a health study because people from all 50 states in the U.S. are participating.

The United States Radiologic Technologists (USRT) Study includes 146,000 radiologic technologists who were registered with ARRT for at least two years prior to 1982.

The original goal of the study was to determine whether repeated low-dose occupational ionizing radiation exposure, such as that potentially experienced by radiologic technologists, was related to cancer and other health conditions. Since its beginning in 1983, the focus of the study has evolved as biomedical science has advanced. The potential health consequences of occupational ionizing radiation exposure can now be examined with a better understanding of the molecular biology of cancer. It is well recognized that risks from environmental and occupational exposures are not equal across all people, with susceptibility influenced by a person’s genetic makeup and other factors.
