| This working data file set, prepared by the Los Alamos National Laboratory Occupational Medicine Group, consists of five working files of demographic, vital status, and exposure data for workers employed at the Pantex Plant located near Amarillo, Texas, during 1951 to 1981. |
| The first file, PXFACW01_d1, contains basic demographic data on 7,425 male and female workers employed either by the prime contractor or by a subcontractor. The hire and termination data cover the period from the start of plant operations in 1951 through late 1981, with some dates beyond. These data were abstracted by project staff primarily from personnel records microfilmed at the Pantex Plant. The cohort roster was assembled from employee record cards, employment information sheets, SSA 941A forms, and health physics records. Vital status was assessed from a number of sources including the SSA, the Pantex Plant records, the Texas Department of Motor Vehicles, and telephone tracing. Vital status tracing was through 1993. Death certificates were obtained from state vital registrars. Death certificates were coded by trained nosologists according to the Eighth revision of the International Classification of Diseases, adapted for use in the United States. The file was extracted from the Los Alamos National Laboratory Epidemiology Section's Pantex database in October 1993 and reflects all demographic and death information present in the database at that time. |
| The second file, PXFACW01_d2, contains exposure data on 209 male and female workers employed at the Pantex Plant. The file consists of each individual's identification number and the date his/her exposure reached or exceeded 1 rem. File PXFACW01_d2 was extracted from Pantex health physics records. The records of individuals having exposures were examined to determine when that individual's exposure reached or exceeded 1 rem. The file contains one record per person. |
| The other three files (PXFACW01_d3, PXFACW01_d4, and PXFACW01_d5) were received from the Pantex Plant in the early 1980s and have not been used or altered. The variable definitions for these files are limited to what was included in the sparse documentation from Pantex. Except for the addition of identification numbers and the CEDR-mandated data truncation, these data are included exactly as they were received from Pantex. |
| The third file, PXFACW01_d3, consists of 209 records containing identification and radiation exposure data on terminated male and female workers at Pantex. The personnel exposure data are whole-body, internal, organ, skin, extremity, and other exposures by current year. Whole-body, internal, skin, extremity, and other exposure measurements are recorded in millirem. |
| The fourth file, PXFACW01_d4, consists of 705 records containing identification and radiation exposure data on inactive male and female workers or buildings at Pantex. The exposure data are whole-body, internal, organ, skin, extremity, and other exposures by current year. Whole-body, internal, skin, extremity, and other exposure measurements are recorded in millirem. |
| The fifth file, PXFACW01_d5, consists of 897 records containing identification and radiation exposure data on active male and female workers or buildings at Pantex. The exposure data are more detailed than those in the PXFACW01_d3 and PXFACW01_d4 files. The whole-body, internal, organ, skin, extremity, and other exposures are included for the current year, prior to the current year, and monthly for the current year. Whole-body, internal, skin, extremity, and other exposure measurements are recorded in millirem. |
