| The ORISEWDS working data file set is comprised of a collection of working files that were developed by the Center for Epidemiologic Research (CER), Medical Sciences Division, Oak Ridge Institute for Science and Education (ORISE). CER obtained these data in various formats and media from the K-25, X-10, Y-12, Linde, Savannah River, Mallinckrodt and Fernald facilities, where the workers were employed and from several other agencies, such as the Social Security Administration. To ensure the integrity of the data in the transcription from hard copy to electronic media, a double-entry method was used whereby one person entered the data and a second person entered the same data for verification purposes. |
| The files in the ORISEWDS working data set originated as part of CER's data model, a relational data base of epidemiologic data. Most of the files contain a large volume of data, which usually pertain to more than one site or facility, and are maintained in a relational data base management system. This design provides efficient data storage and facilitates the frequent addition of new or corrected data. The dynamic nature of the data model means that the working files comprising the ORISEWDS data file set are a snapshot of the files at CER and that subsequent updates that will be placed in CEDR may be different from the current working files in the ORISEWDS data file set. |
| The files in the ORISEWDS are roughly segregated by type of data rather than by facility. Each worker has been assigned a unique pseudo-identification number, which can be used to relate data that may appear in a number of files. This allows users to compile all data for a given individual or cohort. |
| There are eleven files in the ORISEWDS data file set that primarily contain demographic and work history data. They are ORISEWDS_d1 (MR), ORISEWDS_d2 (EMP), ORISEWDS_d3 (PAYCD), ORISEWDS_d4 (JOB), ORISEWDS_d5 (DEPTCD), ORISEWDS_d6 (MVITAL), ORISEWDS_d7 (DEATH), ORISEWDS_d70 (DEATH_OTHER_CAUSES), ORISEWDS_d8 (ERROR) , ORISEWDS_d9 (FIXED), and ORISEWDS_d10 (MERGED). The MR (master roster) file contains one record per person. All other files may have multiple records, or no records, for an individual, depending on the type and availability of the data. The remaining working files in the ORISEWDS data file set contain data relating to personal radiation monitoring information that were obtained from various facilities at which the individual worked. Due to the volume and nature of these data, they are segregated by facility and by type of monitoring, such as external monitoring, whole-body counting, and urinalysis results. The individual identification numbers in these files allow these data to be linked to pertinent data that may appear in other files in the ORISEWDS data file set. Therefore, the proper combination of files will provide a complete picture of data for an individual or for a particular cohort of interest. More detailed information about each of the working files in the ORISEWDS data file set is provided in the file-level structured documentation. |
| These working data include three files concerning the Fernald site. File ORISEWDS_d11 (FMPCFB) contains Fernald film badge data, file ORISEWDS_d12 (FMPCWBC) contains whole body count data, and file ORISEWDS_d13 (FMPCURIN) contains urinalysis data. |
| Similarly, three working data files each are included concerning the K25 site and the X10 site. File ORISEWDS_d14 (K25EXT) contains external monitoring data, file ORISEWDS_d15 (K25WBC) contains whole body count data, and file ORISEWDS_d16 (K25URIN) contains urinalysis data. File ORISEWDS_d17 (X10EXT) contains external monitoring data, file ORISEWDS_d18 (X10WBC) contains whole body count data, and file ORISEWDS_d19 (X10URIN) contains urinalysis data. The Y12 site is described by five files, ORISEWDS_d20 (Y12EXT5080) contains external monitoring data for 1950-1980, ORISEWDS_d21 (Y12EXT8184) contains external monitoring data for 1981-1984, ORISEWDS_d22 (Y12EXT8588) contains external monitoring data for 1985-1988, file ORISEWDS_d23 (Y12WBC) contains whole body count data, and file ORISEWDS_d24 (Y12URIN) contains urinalysis data. |
| File ORISEWDS_d25 (LINDEFB) contains external monitoring data. |
| Four working data files are included concerning the Savannah River site. File ORISEWDS_d26( SRABSTRACTED) is a subset of SRS exposure/monitoring data. ORISEWDS_d28 (SRHPAREA1) and ORISEWDS_d29 (SRHPAREA2) contain Savannah River monitoring data. File ORISEWDS_d27 (SRFAYERWETHER) contains additional dosimetry data. |
| Four working data files are included concerning the Mallinckrodt Chemical Works site. File ORISEWDS_d30 (MCW_FB) includes film badge data, ORISEWDS_d31 (MCW_URIN) is a urinalysis file, ORISEWDS_d32 (MCW_X-RAY) has X-ray data, and ORISEWDS_d33 (MCW_BRTHRADON) has radon breathing zone data. |
| Files ORISEWDS_d34 through ORISEWDS_d49 contain information as reflected by the file name. |
