HPA Press Release - X-ray radiation doses continue to fall
The Health Protection Agency (HPA) of the
United Kingdom recently issued the press release "X-ray
radiation doses continue to fall." The HPA reports that "the
amount of radiation to which patients are exposed when they have medical x-rays
is continuing to fall, according to the Health Protection Agency's latest
five-yearly review of the National Patient Dose Database."
Dr. Fred Mettler, Jr., provided comment to the HPS website staff when asked
about the paper he presented at the annual meeting of the National
Council on Radiation Protection and Measurements (NCRP), which concluded,
"The average
U.S.
resident American is exposed to nearly six times as much radiation from medical
devices than in 1980." Dr. Mettler, commenting that the HPA report is very
"thorough and useful," pointed out that it only addresses
individual procedure doses without discussion of population doses, which
his report addressed. In the
United States,
we are also looking at dosimetry variations due to the increased use of computed
radiography (CR), which increases patient dose, and digital radiography (DR), which
decreases patient dose. Perhaps more importantly, the HPA study does
not include computed tomography (CT) procedures, the major contributor to
increased population dose in the
United States.
