RADON 293. HEALTH EFFECTSsome cohorts mining other metals, hard rock, or coal. The results of these studies consistentlydemonstrate increased risk of mortality from lung cancer with increasing WLM (see Table 3-2). Lubin etal. (1997) provide the most recent report of pooled results from eleven of these cohorts. The pooled dataincluded 115 lung cancer deaths among workers without known occupational exposure to radon and2,674 lung cancer deaths among exposed miners. Some of these miners had been exposed to more than10,000 WLM; the mean exposure among the pooled miner data was 162 WLM. Restricting exposedminer groups by cumulative exposure (
