The lifetime attributable risk of cancer above baseline for specific radiation-producing examinations. The lifetime attributable risk of cancer was calculated using median measured exposure for all cardiac catheterization procedures and estimated exposure based on previously published data for all other radiation-producing examinations.^{Appendix 1} The lower and upper limits are based on the BEIR VII confidence intervals. A lower and upper limit estimate was calculated for each examination on each patient, and the data presented represent the median cohort values for these limits. CT = computed tomography; GI = gastrointestinal; KUB = kidneys ureters bladder; AP = anteroposterior; PA = posteroanterior.
