Medical Radiation Exposure of the U.S. Population Greatly Increased Since the Early 1980s
The increase was primarily a result of the growth in the use of medical imaging procedures, explained Dr.
The NCRP Report No. 160, Ionizing Radiation Exposure of the Population of
Background radiation, which in 2006 contributed fully half of the total exposure, comes from natural radiation in soil and rocks, radon gas which seeps into homes and other buildings, plus radiation from space and radiation sources that are found naturally within the human body.
Other small contributors of exposure to the U.S. population included consumer products and activities, industrial and research uses and occupational tasks.
NCRP is working with some of its partners like the American College of Radiology (ACR), World Health Organization and others to address radiation exposure resulting from the significant growth in medical imaging and to ensure that referrals for procedures like CT and nuclear medicine are based on objective, medically relevant criteria (e.g. ACR appropriateness criteria).
This year marks the 80th anniversary of NCRP’s founding and the 45th anniversary of its charter from the U.S. Congress under Public Law 88-376.
A limited number of prepublication copies of Report No. 160 will be available during the NCRP annual meeting on
