| This analytic data file set consists of one file generated for a cohort mortality and morbidity of white male welders employed at one or more of the three Oak Ridge facilities study by AP Polednak, published in Archives of Environmental Health in 1981. |
| This study examined mortality from various diseases, including cancer of the respiratory system, in a cohort of 1,059 white male welders exposed to nickel compounds. The study also examined the long-term health effects of exposure to several other compounds (dust, fumes, and gases) among welders. A subgroup of these welders was exposed to nickel oxides at the Oak Ridge K-25 Facility, formerly known as the ORGDP. These workers were subjected to air concentrations of nickel higher than proposed standards. However, SMRs for lung cancer and diseases of the respiratory system were not higher among K-25 welders than among other welders. |
| The single analytic file, ORMULA01_d1 (ANALYSIS), in this data file set contains demographic and vital status data for 1,062 individuals. There is one record per person. Three individuals were not included in the final analyses. Radiation monitoring data were not used in the analysis. |
| The study cohort of 1,059 white male welders was determined by examining work histories (payroll records) that specified job titles and job codes indicative of welding. Industrial hygienists at the plant were consulted to avoid possible exclusion of job titles and job codes associated with welding on a full-time basis. Vital status was ascertained for approximately 92% of the study cohort through December 31, 1974, the study end date. There were 173 deaths identified, and death certificates were obtained for 166 (95.9%) of these deaths. Personal radiation monitoring data were not used |
