Former FDA scientist alleges agency discounted concerns about radiation exposure in medical scans

A former Food and Drug Administration scientist said Tuesday his job was eliminated after he raised concerns about the risks of radiation exposure from high-grade medical scanning. Dr. Julian Nicholas told an audience of imaging specialists in Washington that he and other FDA staffers “were pressured to change their scientific opinion†by managers in the agency’s medical device division.
Nicholas, now a physician at the Scripps Clinic in San Diego, said he and eight other staffers raised their concerns with the division’s top director last September.
“Scientific and regulatory review process for medical devices was being distorted by managers who were not following the laws,†Nicholas said. A month later Nicholas’ position was “terminated,†he said.
The allegations about suppression of scientific dissent within FDA are not the first, and come at an inopportune time for the agency. Tuesday’s meeting was designed to kick off the FDA’s campaign to reduce radiation exposure from medical scanning.
The agency is seeking input from physicians and manufacturers on additional safety controls and training to improve CT scanners and other medical imaging devices. Hundreds of studies have linked certain types of radiation, including the type used in medical imaging, to cancer that can surface decades later.
FDA medical reviewer Dr. Robert Smith, who also presented at Tuesday’s public meeting, said he hoped the FDA would learn a lesson from Nicholas’ experience. “Science must not be ignored, suppressed or distorted as that endangers the public,†Smith told the audience.
Agency spokesman Dick Thompson said in a statement the FDA’s inspector general looked into Nicholas’ allegations of retaliation against agency scientists and did not pursue further action or investigation. The agency’s policies do not allow staffers to be penalized for expressing scientific views, he added.
