provided by the
Networked Digital Library of Theses and Dissertations.
Our metadata is collected from universities around the world. If you manage a university/consortium/country archive and want to be added, details can be found on the NDLTD website.

Public health implications of medical diagnostic radiation exposureGerstenmaier, Jan Frank 02 1900 (has links)
Radiation from Computed Tomography (CT) is now the major contributor to population
radiation dose. Despite controversy around the dose-effect relationship of radiation from
CT, the linear non-threshold (LNT) theory is endorsed by many authorities, and
constitutes the basis of cancer risk estimates. The purpose of this study was (1) a
literature review of radiobiological theories, and methods of dose saving stategies in
CT; (2) to highlight the importance of dose saving in CT, and to demonstrate how dose
can be saved in a radiology department: Following a 40% reduction in reference X-ray
tube current for a CT of the urinary tract, the effecitve dose and estimated lifetime
attributable risk of incident cancer due to this CT in a group (n=103) were reduced by
37% and 38% in an age and sex-matched group respectively. The literature review
showed that the public health implications of CT radiation exposure remain uncertain. / Health Studies / M.A. (Public Health)
