Cohort study <strong>of</strong> respiratory<br />
cancer in 4,146 U.S. miners<br />
1950-1960<br />
Archer et<br />

RR 28.6 (13.2-61.7) for uranium miners compared<br />
to non-uranium miners<br />
Mean cumulative exposure<br />
1635 WLM (1969-83) and<br />
1292 WLM (1984-1993)<br />
Cohort study <strong>of</strong> lung cancer<br />
mortality in 757 Navajo miners<br />

0->1,450 WLM RR 29.2 (5.1-167.2) for miners with 1,450 WLM<br />
exposure compared to those with less than 80<br />
WLM. Inverse dose-rate effect especially at low<br />
doses. Non-smoker uranium miners’ excess risk is<br />
3 times that <strong>of</strong> smokers for lung cancer<br />
