The number of mammographic examinations performed annually in the province of Manitoba, Canada, and their associated radiation doses (total collective breast dose and average glandular dose (AGD) per view) are reported for the period 1978-1988. These data indicate that the total number of examinations performed annually increased by a factor of five during the 11-year study. The total annual collective breast dose, meanwhile, increased at a much slower rate, from 40 person-Gy in 1978 to 97 person-Gy in 1988; this difference is attributable to the gradual replacement of xeroradiography by screen-film mammography and to changes in technique. In the late 1980s, the AGD due to xeroradiography for a craniocaudal view was 3.3 mGy, a factor of 2.4 greater than the corresponding dose associated with dedicated screen-film units.
