Risk Coefficients — oe — Q . V fyi CAR CAPS At the time the Bikini book was prepared no agency in the U.S. government had accepted the risk coefficients in BEIR-III. to use risk coefficients from BEIR-I. Thus we were constrained While not included in the printed book, risk estimates based on BEIR-III were calculated for comparison purposes. The following gives the origin of the risk coefficients used. :
