We frequently receive questions on the Ask the Experts (ATE) feature of the Health Physics Society website from people who have received one or more diagnostic medical exams. These people express concern about the risks of the radiation exposure(s) from these exams.

We always encourage people to become well informed about the risks and benefits of all uses of radiation, and in the case of medical exposures, it is good to be an active participant in the process. This includes an understanding of the procedures involved and the possible risks associated with them.

We routinely answer this kind of ATE question with as much information taken from various standard published data sources as we can provide about typical radiation doses for the procedure. However, only the physician, physicist, and other professionals from the institution where the procedure is performed can provide specific radiation dose information for the particular exams and techniques employed.

We usually add a statement that "any theoretical risks of the radiation exposures that you received were far smaller than the direct benefits of the study." We say "theoretical" because all risk information is based on the so-called "linear no-threshold" (LNT) theory, which assumes that risks (mostly of cancer) observed in populations exposed to high doses of radiation can be extrapolated to the much lower doses that we deal with in diagnostic medical procedures, radiation-worker situations, and other circumstances. By "extrapolation" we mean that a straight line is drawn through the risk-versus-dose data available at higher doses (typically at least 10-fold higher than diagnostic or occupational doses) and this line is then extended down to zero dose.

No one knows if this extrapolation is valid, but it is used to set radiation dose limits for workers, make general evaluations about risks and benefits of medical exposures, and estimate risks in other applications. Some have used this model to state as fact that thousands of excess cancer deaths will occur in populations exposed to low doses of radiation, but this is not supported by the available science—we don't know for a fact that low (that is, diagnostic and occupational) levels of radiation are associated with increased risks of developing cancer. Many believe that the LNT approach overestimates the actual risks at such low doses and some even believe that there is evidence for a threshold for such effects, that is, that there may be a non-zero radiation dose below which there is NO increased risk of cancer. Others believe that the best explanation of available data is given by an LNT model. Importantly, the data upon which the LNT model is based begin at doses above 100 mSv.
