TABLE 7.
Estimates of Excess Relative Risk (ERR) per Gy for Plutonium, Attained Age Parameter, and ERR per Gy for External Dose by the Data Used and By Whether or Not Autopsy Data Used for Estimating Plutonium Doses for 406a Workers Who had Such Data
| Data used | Autopsy data used? | ERR per Gy for plutonium dose at age 60
|
Attained age parameter | ERR per Gy for external dose | |
|---|---|---|---|---|---|
| Males | Females | ||||
| Subjects and person-years with plutonium dose estimates | No | 7.4 (5.0 to 11) | 24 (11 to 56) | −3.1 (−5.4 to −0.8) | 0.13 (−0.04 to 0.38) |
| Yes | 6.5 (4.4 to 9.4) | 19 (8.2 to 43) | −3.2 (−5.5 to −0.8) | 0.21 (0.02 to 0.48) | |
| All datab | No | 8.2 (5.7 to 12) | 20 (11 to 38) | −3.6 (−5.7 to −1.4) | 0.19 (0.04 to 0.38) |
| Yes | 7.0 (4.8 to 9.9) | 17 (8.4 to 31) | −3.5 (−5.7 to −1.4) | 0.24 (0.08 to 0.44) | |
The original number was 507, but only 406 workers were monitored more than 2 years preceding death and otherwise qualified for the study cohort.
The plutonium surrogate (Sokolnikov et al.) was used for subjects whose plutonium doses could not be estimated; these subjects contributed to estimating baseline and external dose parameters, but not to estimating plutonium dose-response parameters.
