Does radiation exposure produce a protective effect among radiologists?

Abstract: AB: The mortality experience of radiologists compared to that of other physician specialists demonstrates an increased risk of cancer deaths as well as deaths from all causes among physicians practicing in the early years of this century. However for the radiologists who joined specialty societies after 1940 the age pattern of deaths has changed. Whereas among early entrants young radiologists had higher mortality rates than those of other specialists among later entrants the young radiologists have lower mortality. However as these later-entrant radiologists age their rates appear to exceed those of other specialists. Although the level of radiation exposure is unknown physicians in more recent years usually have lower cumulative doses. Lower radiation exposure may be one of a number of possible explanatory factors for the cross-over from "protected" to "higher risk" status as these physicians age. hl
