Scientists to go public on radiology fears

WASHINGTON, March 29 (UPI) -- Scientists concerned about risks associated with growing use of radiology in the United States say they are set to take their concerns public this week.

The scientists say they will speak up Tuesday at a Food and Drug Administration meeting on protecting patients from unnecessary exposure to radiation, The New York Times reported. The FDA has routinely disregarded urgent warnings by government experts about potential risk from routine use of CT scans for colon cancer screening, the newspaper said, citing FDA documents and interviews with agency scientists.

The FDA meeting is said to be part of the agency's re-evaluation of risks associated with routine radiology, the newspaper said.

An estimated 70 million CT scans are administered annually in the United States -- up from about 3 million three decades ago. Researchers estimate as many as 14,000 people die each year of cancers resulting from such exposure, the Times reported.
