(a) The goals reflect the activity in a 24 hour fecal sample corresponding to either a 50 rem CDE or a
0.1 rem CEDE.
(b) IRF values obtained from GENMOD Computer Code (Version 3.0.3).
(c) Calculated as Goal (dpm) = Intake * IRF * 2220 dpm/nCi, where Intake (nCi) is the 50 rem CDE dose limit/dose
conversion factor and IRF is the intake retention fraction.
The dose conversion factor (committed dose per unit intake) derived from Federal Guidance Report No. 11 (EPA,
1988b), Table 2.1 is shown below:

(d) Calculated as Goal (dpm) = Intake * IRF * 2220 dpm/nCi, where Intake (nCi) is the 0.1 rem CEDE dose
threshold/dose conversion factor and IRF is the intake retention fraction.
The dose conversion factor (committed dose per unit intake) derived from Federal Guidance Report No. 11 (EPA,
1988b), Table 2.1 is shown below:
