This abstract describes the final report (EPRI TR-107059) for this data set.
This document describes the Telephone Line Workers Data Set containing the measurement data collected during the EPRI-sponsored study, Leukemia in Telephone Linemen (RP2964-04). The data were supplied to the EPRI EMF Exposure Database by the original researchers at Johns Hopkins University (JHU). The three data products in the Telephone Line Workers Data Set contain the magnetic field personal exposure measurements collected during the study and summaries of those measurements. The three exposure measurement data products are: the binary and ASCII time-series files of individual measurements and a summary file with records for each measured worker. The time-series files represent over 780,000 individual magnetic field measurements. The summary file contains records for each of the 204 measurement sessions, with the 33 24-hour sessions being split into work and nonwork periods for summarization. A record in the summary file contains a collection of calculated values for the measurements being summarized and categorical variables describing the session and worker. Telephone workers were placed in one of four categories depending on the tasks they performed. The documentation contains a project synopsis, full descriptions of all data elements, and the format and size of each data product. The final report for the project and other references are cited as sources of detailed information about study design, protocols, and results.
