Brief Summary

RATIONALE: Electric and magnetic fields may increase the risk of cancer. Developing interview questions that accurately estimate a person's 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.
