| This working data file set, prepared by PNL, consists of seven working files for Hanford operations and construction workers during 1944 to 1989 and was used as data sources for the 1992 Hanford Mortality Study (HMS) database. |
| Job histories, external radiation data, internal deposition data, mortality information, and the 1979 master data file are provided by the Health Risk Assessment Department (HRAD) of PNL for individuals employed at Hanford. The master data file was generated by HRAD in 1979. The contents of the other working files are supplied as received from either the Operations Analysis Department of HEHF or the Health Physics Department (HPD) of PNL. These seven files are defined as source files in the PNL Technical Report No. PNL-8449, Description of the Process Used to Create the 1992 Hanford Mortality Study Database (E.S. Gilbert, et al., December 1992). Each one was a data source used by HRAD to generate the working files in the HFW89W01 data file set that were used to create the 1992 Hanford Mortality Study database. |
| Occupational data for Hanford employees, and mortality information for former employees, are collected, maintained, and periodically updated by HEHF. External radiation exposure data, estimated from personal dosimeters, are routinely collected and maintained by HPD. Exposure data from internal monitoring are also routinely collected and evaluated by HPD for employees who worked in locations where there was a potential for intake of radioactive material (transuranics). |
| HFSRCW01_d1 (OHH88_OP) is an unedited working file of 1944 to 1988 job histories for all individuals, other than those employed only as construction workers, initially employed at Hanford from 1944 to 1983 by DOE contractors. These individuals are referred to as operations workers. This file was generated from the occupational health history (OHH) file received from HEHF in 1988. Each individual in the OHH file had one personnel identification record and usually several work history records. A work history record was created each time certain job changes occurred. HFSRCW01_d1 (OHH88_OP) has a total of 484,527 records for the 52,522 operations workers that have job histories. |
| HFSRCW01_d2 (OHH88_CO) is an unedited working file of 1944 to 1988 job histories for all individuals initially employed at Hanford, from 1944 to 1983, only as construction, DOE, or site service workers. This file was generated from the OHH file received from HEHF in 1988. HFSRCW01_d2 (OHH_CO) has a total of 8,651 records for the 2,285 non-operations workers that have job histories. |
| HFSRCW01_d3 (ORE_44) is an unedited working file of external dosimetry data for workers initially employed at Hanford in the years 1944 to 1982. This file of occupational radiation exposure (ORE) data, which includes off-site occupational exposures, was received from HPD in 1990. HFSRCW01_d3 (ORE_44) has a total of 333,020 records for the 33,092 workers that were monitored. |
| HFSRCW01_d4 (ORE_83) is an unedited working file of external dosimetry data for workers initially employed at Hanford in the years 1983 to 1989. This file of ORE data, which includes off-site occupational exposures, was received from HPD in 1990. The type of dosimetry information provided differs from the information available for the years 1944 to 1982. HFSRCW01_d4 (ORE_83) has a total of 151,022 records for the 16,821 workers that were monitored. |
| HFSRCW01_d5 (INDEP) is an unedited working file of internal deposition data for Hanford workers with confirmed internal depositions of various radionuclides, including plutonium, in the years 1944 to 1989. This file was received from HPD in 1991. HFSRCW01_d5 (INDEP) has a total of 624 records for 560 workers. |
| HFSRCW01_d6 (HMO91) is an unedited working file of mortality data for former Hanford workers identified as dying in the years 1944 to 1991. This file was received from HEHF in 1991. HFSRCW01_d6 (HMO91) has one record for each of the 10,922 deceased workers. |
| HFSRCW01_d7 (MST79) is the master data file consisting of merged information about job histories, external dosimetry, internal depositions, and mortality data for operations workers initially employed at Hanford in the years 1944 to 1978. A detailed account of the process used to create this file is described in Appendix A of the referenced technical report. HFSRCW01_d7 (MST79) has one record for each of the 44,101 operations workers that had job histories. |
