OBJECTIVES:
* Validate an interview-based electric and magnetic field exposure (EMF) assessment algorithm against measurements of the time-weighted average magnetic field magnitude used in previous epidemiologic studies.
* Calibrate the parameters in the algorithm in order to improve the exposure estimates.
* Correlate EMF exposure estimates from the algorithm with biologically based metrics measured by new instrumentation.
OUTLINE: Participants respond to questions during a 5- to 15-minute telephone interview concerning workplace exposure to electric and magnetic (EMF) fields. Data is collected during the interview using an exposure assessment algorithm designed to estimate EMF workplace exposure based on participants' responses. The interview-based estimates are then validated against actual field measurements of magnetic field exposure captured by Emdex multiwave monitors located at participating sites.
