Brief Summary:
RATIONALE Electric and magnetic fields may increase the risk of cancer Developing interview questions that accurately estimate a persons exposure to electric and magnetic fields may help doctors learn about the long-term effects of workplace exposure
PURPOSE This clinical trial is developing interview questions that can be used in estimating workplace exposure to electric and magnetic fields
PURPOSE This clinical trial is developing interview questions that can be used in estimating workplace exposure to electric and magnetic fields
Detailed Description:
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
