Table 7 Stochastic cancer risk calculation (incidence) for size specific dose estimated displayed and calculated using BEIR VII report, mean ± SD

Parameter	SSDE displayed	SSDE calculated
Dose	41.63 ± 2.07	46.94 ± 2.07
Calculated mean risk (LAR)	9.57 × 10^-5	1.08 × 10^-4
Risk probability	1 in 10450	1 in 9260
Risk range (± 1 SD)	9.10 × 10^-5-1.00 × 10^-4	1.03 × 10^-4-1.13 × 10^-4

SSDE: Size specific dose estimated; LAR: Lifetime attributable risk.
