Description:
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 ten files in the ORISEWDS data file set that primarily contain demographic and work history data. They are MR, EMP, PAYCD, JOB, DEPTCD, MVITAL, DEATH, ERROR, MERGED, and FIXED. 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 FMPCFB contains Fernald film badge data, file FMPCWBC contains whole body count data, and file FMPCURIN contains urinalysis data.
Similarly, three working data files each are included concerning the K25 site and the X10 site. File K25EXT contains external monitoring data, file K25WBC contains whole body count data, and file K25URIN contains urinalysis data. File X10EXT contains external monitoring data, file X10WBC contains whole body count data, and file X10URIN contains urinalysis data. The Y12 site is described by five files, Y12EXT5080 contains external monitoring data for 1950-1980, Y12EXT8184 contains external monitoring data for 1981-1984, Y12EXT8588 contains external monitoring data for 1985-1988, file Y12WBC contains whole body count data, and file Y12URIN contains urinalysis data.
File LINDEFB contains external monitoring data.
Four working data files are included concerning the Savannah River site. File SRABSTRACTED is a subset of SRS exposure/monitoring data. SRHPAREA1 and SRHPAREA2 contain Savannah River monitoring data. File SRFAYERWETHER contains additional dosimetry data.
Four working data files are included concerning the Mallinckrodt Chemical Works site. File MCW_FB includes film badge data, MCW_URIN is a urinalysis file, MCW_X-RAY has X-ray data, and MCW_BRTHRADON has radon breathing zone data.
