Medical radiation exposures in occupational studies: discussion.
Radiat Res 2002 Dec; 158(6):808
The presentations in this session are linked by the populations studied (occupational cohorts), by the exposure setting (incidental or intentional exposure to medical sources of ionizing radiation), and by the aim of the studies, which is to evaluate risk of cancer after exposure to ionizing radiation. Continued interest in the effects of low-dose exposure to ionizing radiation places these occupational radiation research studies at the forefront of the current debate about the limits of epidemiology. Among the most pressing aspects of these potential limits is the ability within low-dose studies to adjust for sources of bias (e.g. due to selection and information) and error (e.g. in measurement of exposures or confounding factors) (1, 2). All four presentations made in this session illustrate attempts to circumvent these limitations and to improve the ability to measure low-dose effects of exposure to ionizing radiation.
